The 69000 integrates 2MB of high-speed SDRAM frame BASIC MODELS) buffer memory into the chip. By embedding SDRAM and graphics controller logic on the same die, the 69000 delivers uncompromising performance. The increase in the frame buffer bandwidth enables the 69000 to support high-color, high-resolution graphics modes and real-time video acceler- ation. The interface supports pixel resolutions up to 1600 x 1200 non-interlaced. Software drivers for enhanced performance and resolution are available for most popular operating systems. SYSTEM The system hardware monitoring system monitors system voltages, temperature and fan HARDWARE speeds. MONITOR The circuitry is based on National Semiconductor's LM80. The LM80 monitors seven system voltages, two fan speeds and the board ambient temperature. All of the voltages, fan speeds and temperature measurements have associated programmable watchdog limits. When any of these programmed limits are exceeded, the monitor software can be used to notify the SBC. In addition, the externally available OS# signal can be used to notify external hardware of any over-temperature condition. Fan speed monitoring can be configured to monitor two system fans. TRENTON Technology Inc. 1-9 Specifications CBI/CGI Technical Reference The LM80 also monitors an external chassis intrusion switch via the system hardware monitor connector (P18). A general purpose output (GPO) is also provided at the system hardware monitor connector. This signal can be used to provide a user-defined function. The following system voltages are monitored by the LM80: • -12 volts • 3.3 volts provided by the on-board voltage regulator for components on the SBC • 3.3 volts backplane power used by the option slots • +5 volts • +12 volts • VCC_CORE, voltage provided by on-board VRM • 1.5 volt, VTT voltage used by processor's GTL+ bus 10/100BASE-T The PCI Ethernet interface is implemented using an Intel 82559 and operates in ETHERNET 10Base-T and 100Base-TX Fast Ethernet modes.

This utility is described in Appendix C - SCSISelect Configuration Utility. 1-10 TRENTON Technology Inc. CBI/CGI Technical Reference Specifications PCI ENHANCED Dual high performance PCI Bus Master EIDE interfaces are capable of supporting two IDE ULTRA IDE Type 4 disk drives each in a master/slave configuration. The interface supports DMA/33 Ultra DMA/33 with synchronous DMA mode transfers up to 33MB per second. INTERFACE (DUAL) FLOPPY DRIVE The SBC supports two floppy disk drives. Drives can be 360K to 2.88MB, in any INTERFACE combination. SERIAL INTERFACE Two high-speed FIFO (16C550) serial ports with independently programmable baud rates are supported. The IRQ for each serial port has BIOS selectable addressing. ENHANCED The SBC provides a PC/AT compatible bidirectional parallel port and supports enhanced PARALLEL parallel port (EPP) mode and extended capabilities port (ECP) mode. The ECP mode is INTERFACE IEEE 1284 compliant. The IRQ for the parallel port has BIOS selectable addressing. PS/2 MOUSE The SBC is compatible with a PS/2-type mouse. The mouse connection can be made by INTERFACE using either the PS/2 mouse header or the bracket mounted PS/2 mouse mini DIN connector. Mouse voltage is protected by a self-resetting fuse. KEYBOARD The SBC is compatible with an AT-type keyboard. The keyboard connection can be INTERFACE made by using either the keyboard header or the bracket mounted keyboard mini DIN connector. Keyboard voltage is protected by a self-resetting fuse. WATCHDOG TIMER The watchdog timer is a hardware timer which resets the SBC if the timer is not refreshed by software periodically. The timer is typically used to restart a system in which an application becomes hung on an external event. When the application is hung, it no longer refreshes the timer. The watchdog timer then times out and resets the SBC. The watchdog timer has two levels of enable. First, the watchdog timer jumper must be moved to the "enabled" position, which puts the watchdog timer under software control. The second level involves software control of the watchdog's timer retriggering. Bit 6 of the 82371EB GPOREG register at I/O address 437H must be set to a zero (0), which blocks the triggering clock to the watchdog timer circuit, thus scheduling a hardware reset in about 1.5 seconds. To refresh the watchdog timer, the software in the application toggles bit 6 of the GPOREG register. First the bit must be set to a one (1) to clear the watchdog timer delay; then it must be set to a zero (0), which schedules a system reset in 1.5 seconds. Toggling bit 6 of the GPOREG must occur within a period of less than 1.5 seconds to insure that a system reset is not issued. A set of watchdog timer software code and sample programs are available from Technical Support. POWER FAIL A hardware reset is issued when on-board +5V voltage drops below 4.75 volts. In DETECTION addition, if the 3.3V Monitor jumper (JU15) is enabled, a reset is issued if 3.3V is below tolerance. (See the Configuration Jumpers section later in this chapter.)

CBI/CGI Technical Reference ISA/PCI Reference ISA BUS SIGNAL The following is a description of the ISA Bus signals. All signal lines are TTL- DESCRIPTIONS compatible. AEN (O) Address Enable (AEN) is used to degate the microprocessor and other devices from the I/O channel to allow DMA transfers to take place. When this line is active, the DMA controller has control of the address bus, the data-bus Read command lines (memory and I/O), and the Write command lines (memory and I/O). BALE (O) (Buffered) Address Latch Enable (BALE) is provided by the bus controller and is used on the system board to latch valid addresses and memory decodes from the microprocessor. It is available to the I/O channel as an indicator of a valid microprocessor or DMA address (when used with AEN). Microprocessor addresses SA[19::0] are latched with the falling edge of BALE. BALE is forced high during DMA cycles. BCLK (O) BCLK is the system clock. The clock has a 50% duty cycle. This signal should only be used for synchronization. It is not intended for uses requiring a fixed frequency. CHRDY (I) I/O Channel Ready (CHRDY) is pulled low (not ready) by a memory or I/O device to lengthen I/ O or memory cycles. Any slow device using this line should drive it low immediately upon detecting its valid address and a Read or Write command. Machine cycles are extended by an integral number of clock cycles. This signal should be held low for no more than 2.5 micro- seconds. D[15::0] (I/O) Data signals D[15::0] provide bus bits 15 through 0 for the microprocessor, memory, and I/O devices. D15 is the most-significant bit and D0 is the least-significant bit. All 8-bit devices on the I/O channel should use D[7::0] for communications to the microprocessor. The 16-bit devices will use D[15::0]. To support 8-bit devices, the data on D[15::8] will be gated to D[7::0] during 8-bit transfers to these devices. 16-bit microprocessor transfers to 8-bit devices will be converted to two 8-bit transfers. DAK[7::5]#, DAK[3::0]# (O) DMA Acknowledge DAK[7::5]# and DAK[3::0]# are used to acknowledge DMA requests DRQ[7::5] and DRQ[3::0]. They are active low. DRQ[7::5], DRQ[3::0] (I) DMA Requests DRQ[7::5] and DRQ[3::0] are asynchronous channel requests used by peripheral devices and the I/O channel microprocessors to gain DMA service (or control of the system). They are prioritized, with DRQ0 having the highest priority and DRQ7 having the lowest. A request is generated by bringing a DRQ line to an active level. A DRQ line must be held high until the corresponding DMA Request Acknowledge (DAK) line goes active. DRQ[3::0] will perform 8-bit DMA transfers; DRQ[7::5] will perform 16-bit transfers. TRENTON Technology Inc. 2-3 ISA/PCI Reference CBI/CGI Technical Reference IO16# (I) I/O 16-bit Chip Select (IO16#) signals the system board that the present data transfer is a 16-bit, 1 wait-state, I/O cycle. It is derived from an address decode. IO16# is active low and should be driven with an open collector or tri-state driver capable of sinking 20 mAmps. IOCHK# (I) I/O Channel Check (IOCHK#) provides the system board with parity (error) information about memory or devices on the I/O channel. When this signal is active, it indicates an uncorrectable system error. IORC# (I/O) I/O Read (IORC#) instructs an I/O device to drive its data onto the data bus. It may be driven by the system microprocessor or DMA controller, or by a microprocessor or DMA controller resident on the I/O channel. This signal is active low. IOWC# (I/O) I/O Write (IOWC#) instructs an I/O device to read the data on the data bus. It may be driven by any microprocessor or DMA controller in the system. This signal is active low. IRQ[15::14], IRQ[12::9], IRQ[7::3] (I) Interrupt Requests IRQ[15::14], IRQ[12::9] and IRQ[7::3] are used to signal the microprocessor that an I/O device needs attention. The interrupt requests are prioritized, with IRQ[15::14] and IRQ[12::9] having the highest priority (IRQ9 is the highest) and IRQ[7::3] having the lowest priority (IRQ7 is the lowest). An interrupt request is generated when an IRQ line is raised from low to high. The line must be held high until the microprocessor acknowledges the interrupt request (Interrupt Service routine). LA[23::17] (I/O) These signals (unlatched) are used to address memory and I/O devices within the system. They give the system up to 16MB of addressability. These signals are valid when BALE is high. LA[23::17] are not latched during microprocessor cycles and therefore do not stay valid for the whole cycle. Their purpose is to generate memory decodes for 1 wait-state memory cycles. These decodes should be latched by I/O adapters on the falling edge of BALE. These signals also may be driven by other microprocessors or DMA controllers that reside on the I/O channel. M16# (I) M16# Chip Select signals the system board if the present data transfer is a 1wait-state, 16- bit, memory cycle. It must be derived from the decode of LA[23::17]. M16# should be driven with an open collector or tri-state driver capable of sinking 20 mAmps. Master16# (I) Master16# is used with a DRQ line to gain control of the system. A processor or DMA controller on the I/O channel may issue a DRQ to a DMA channel in cascade mode and receive a DAK#. Upon receiving the DAK#, an I/O microprocessor may pull Master16# low, which will allow it to control the system address, data, and control lines (a condition known as tri-state). After Master16# is low, the I/O microprocessor must wait one system clock period before driving the address and data lines, and two clock periods before issuing a Read or Write command. If this signal is held low for more than 15microseconds, system memory may be lost because of a lack of refresh. 2-4 TRENTON Technology Inc. CBI/CGI Technical Reference ISA/PCI Reference NOWS# (I) The No Wait State (NOWS#) signal tells the microprocessor that it can complete the present bus cycle without inserting any additional wait cycles. In order to run a memory cycle to a 16-bit device without wait cycles, NOWS# is derived from an address decode gated with a Read or Write command. In order to run a memory cycle to an 8-bit device with a minimum of two wait states, NOWS# should be driven active on system clock after the Read or Write command is active gated with the address decode for the device. Memory Read and Write commands to a 8-bit device are active on the falling edge of the system clock. NOWS# is active low and should be driven with an open collector or tri-state driver capable of sinking 20 mAmps. OSC (O) Oscillator (OSC) is a high-speed clock with a 70-nanosecond period (14.31818 MHz). This signal is not synchronous with the system clock. It has a 50% duty cycle. REFRESH# (I/O) The REFRESH# signal is used to indicate a refresh cycle and can be driven by a micropro- cessor on the I/O channel. RESDRV (O) Reset Drive (RESDRV) is used to reset or initialize system logic at power-up time or during a low line-voltage outage. This signal is active high. SA[19::0] (I/O) Address bits SA[19::0] are used to address memory and I/O devices within the system. These twenty address lines, in addition to LA[23::17], allow access of up to 16MB of memory. SA[19::0] are gated on the system bus when BALE is high and are latched on the falling edge of BALE. These signals are generated by the microprocessor or DMA Controller. They also may be driven by other microprocessors or DMA controllers that reside on the I/O channel. SBHE# (I/O) System Bus High Enable (SBHE#) indicates a transfer of data on the upper byte of the data bus, D[15::8]. 16-bit devices use SBHE# to condition data bus buffers tied to D[15::8]. SMRDC# (O), MRDC# (I/O) These signals instruct the memory devices to drive data onto the data bus. SMRDC# is active only when the memory decode is within the low 1MB of memory space. MRDC# is active on all memory read cycles. MRDC# may be driven by any microprocessor or DMA controller in the system. SMRDC is derived from MRDC# and the decode of the low 1MB of memory. When a microprocessor on the I/O channel wishes to drive MRDC#, it must have the address lines valid on the bus for one system clock period before driving MRDC# active. Both signals are active low. SMWTC# (O), MWTC# (I/O) These signals instruct the memory devices to store the data present on the data bus. SMWTC# is active only when the memory decode is within the low 1MB of the memory space. MWTC# is active on all memory write cycles. MWTC# may be driven by any microprocessor or DMA controller in the system. SMWTC# is derived from MWTC# and the decode of the low 1MB of memory. When a microprocessor on the I/O channel wishes to drive MWTC#, it must have the address lines valid on the bus for one system clock period before driving MWTC# active. Both signals are active low.

TRENTON Technology Inc. 2-7 ISA/PCI Reference CBI/CGI Technical Reference PCI LOCAL BUS The PCI (Peripheral Component Interconnect) Local Bus is a high performance, 32-bit or OVERVIEW 64-bit bus with multiplexed address and data lines. It is intended for use as an inter- connect mechanism between highly integrated peripheral controller components, peripheral add-in boards and processor/memory systems. The "local bus" moves peripheral functions with high bandwidth requirements closer to the system’s processor bus and can produce substantial performance gains with graphical user interfaces (GUIs) and other high bandwidth functions (i.e., full motion video, SCSI, LANs, etc.). The PCI Local Bus accommodates future system requirements and is applicable across multiple platforms and architectures. The PCI component and add-in card interface is processor independent, enabling an efficient transition to future processor generations, by bridges or by direct integration, and use with multiple processor architectures. Processor independence allows the PCI Local Bus to be optimized for I/O functions, enables concurrent operation of the local bus with the processor/memory subsystem, and accommodates multiple high perfor- mance peripherals in addition to graphics. Movement to enhanced video and multimedia displays and other high bandwidth I/O will continue to increase local bus bandwidth requirements. A transparent 64-bit extension of the 32-bit data and address buses is defined, doubling the bus bandwidth and offering forward and backward compatibility of 32-bit (132MB/s peak) and 64-bit (264MB/s peak) PCI Local Bus peripherals. 2-8 TRENTON Technology Inc.

When the # symbol is absent, the signal is active at a high voltage. The following are descriptions of the PCI Local Bus signals. ACK64# (optional) Acknowledge 64-bit Transfer, when actively driven by the device that has positively decoded its address as the target of the current access, indicates the target is willing to transfer data using 64bits. ACK64# has the same timing as DEVSEL#. AD[31::00] Address and Data are multiplexed on the same PCI pins. A bus transaction consists of an address phase followed by one or more data phases. During the address phase, AD[31::00] contain a physical address (32 bits). During data phases, AD[07::00] contain the least signif- icant byte (lsb) and AD[31::24] contain the most significant byte (msb). AD[63::32] (optional) Address and Data are multiplexed on the same pins and provide 32additional bits. During an address phase (when using the DAC command and when REQ64# is asserted), the upper 32bits of a 64-bit address are transferred; otherwise, these bits are reserved but are stable and indeterminate. During a data phase, an additional 32bits of data are transferred when REQ64# and ACK64# are both asserted. C/BE[3::0]# Bus Command and Byte Enables are multiplexed on the same PCI pins. During the address phase of a transaction, these pins define the bus command; during the data phase they are used as byte enables. The byte enables are valid for the entire data phase and determine which byte lanes carry meaningful data. C/BE0# applies to byte0 (lsb) and C/BE3# applies to byte 3 (msb). 2-14 TRENTON Technology Inc. CBI/CGI Technical Reference ISA/PCI Reference C/BE[7::4]# (optional) Bus Command and Byte Enables are multiplexed on the same pins. During an address phase (when using the DAC command and when REQ64# is asserted), the actual bus command is transferred on C/BE[7::4]#; otherwise, these bits are reserved and indeterminate. During a data phase, C/BE[7::4]# are byte enables indicating which byte lanes carry meaningful data when REQ64# and ACK64# are both asserted. C/BE4# applies to byte4 and C/BE7# applies to byte7. CLK Clock provides timing for all transactions on PCI and is an input to every PCI device. DEVSEL# Device Select, when actively driven, indicates that the driving device has decoded its address as the target of the current access. As an input, DEVSEL# indicates whether any device on the bus has been selected. FRAME# Cycle Frame is an interface control pin which is driven by the current master to indicate the beginning and duration of an access. When FRAME# is asserted, data transfers continue; when it is deasserted, the transaction is in the final data phase. GNT# Grant indicates to the agent that access to the bus has been granted. This is a point to point signal. Every master has its own GNT#. IDSEL Initialization Device Select is used as a chip select during configuration read and write transac- tions. INTA#, INTB#, INTC#, INTD# (optional) Interrupts on PCI are optional and defined as "level sensitive," asserted low (negative true), using open drain output drivers. PCI defines one interrupt for a single function and up to four interrupt lines for a multi-function device or connector. Interrupt A is used to request an interrupt. For a single function device, only INTA# may be used, while the other three interrupt lines have no meaning. Interrupt B, Interrupt C and Interrupt D are used to request additional interrupts and only have meaning on a multi-function device. IRDY# Initiator Ready indicates the initiating agent’s (bus master’s) ability to complete the current data phase of the transaction. IRDY# is used in conjunction with TRDY#. During a write, IRDY# indicates that valid data is present on AD[31::0]. During a read, it indicates that the master is prepared to accept data. LOCK# Lock indicates an operation that may require multiple transactions to complete. When LOCK# is asserted, non-exclusive transactions may proceed to an address that is not currently locked. TRENTON Technology Inc. 2-15 ISA/PCI Reference CBI/CGI Technical Reference PAR Parity is even parity across AD[31::00] and C/BE[3::0]#. Parity generation is required by all PCI agents. The master drives PAR for address and write data phases; the target drives PAR for read data phases. PAR64 (optional) Parity Upper DWORD is the even parity bit that protects AD[63::32] and C/BE[7::4]#. The master drives PAR64 for address and write data phases; the target drives PAR64 for read data phases. PERR# Parity Error is for the reporting of data parity errors during all PCI transactions except a Special Cycle. There are no special conditions when a data parity error may be lost or when reporting of an error may be delayed. PRSNT1# and PRSNT2# PRSNT1# and PRSNT2# are related to the connector only, not to other PCI components. They are used for two purposes: indicating that a board is physically present in the slot and providing information about the total power requirements of the board. REQ# Request indicates to the arbiter that this agent desires use of the bus. This is a point to point signal. Every master has its own REQ#. REQ64# (optional) Request 64-bit Transfer, when actively driven by the current bus master, indicates it desires to transfer data using 64 bits. REQ64# has the same timing as FRAME#. REQ64# has meaning at the end of reset. RST# Reset is used to bring PCI-specific registers, sequencers and signals to a consistent state. SBO# (optional) Snoop Backoff is an optional cache support pin which indicates a hit to a modified line when asserted. When SBO# is deasserted and SDONE is asserted, it indicates a "clean" snoop result. SDONE (optional) Snoop Done is an optional cache support pin which indicates the status of the snoop for the current access. When deasserted, it indicates the result of the snoop is still pending. When asserted, it indicates the snoop is complete. SERR# System Error is for reporting address parity errors, data parity errors on the Special Cycle command, or any other system error where the result will be catastrophic. If an agent does not want a non-maskable interrupt (NMI) to be generated, a different reporting mechanism is required. 2-16 TRENTON Technology Inc. CBI/CGI Technical Reference ISA/PCI Reference STOP# Stop indicates that the current target is requesting the master to stop the current transaction. TCK (optional) Test Clock is used to clock state information and test data into and out of the device during operation of the TAP (Test Access Port). TDI (optional) Test Data Input is used to serially shift test data and test instructions into the device during TAP (Test Access Port) operation. TDO (optional) Test Data Output is used to serially shift test data and test instructions out of the device during TAP (Test Access Port) operation. TMS (optional) Test Mode Select is used to control the state of the TAP (Test Access Port) controller in the device. TRDY# Target Ready indicates the target agent’s (selected device’s) ability to complete the current data phase of the transaction. TRDY# is used in conjunction with IRDY#. During a read, TRDY# indicates that valid data is present on AD[31::00]. During a write, it indicates that the target is prepared to accept data. TRST# (optional) Test Reset provides an asynchronous initialization of the TAP controller. This signal is optional in the IEEE Standard Test Access Port and Boundary Scan Architecture.

CBI/CGI Technical Reference System BIOS Chapter 3 System BIOS BIOS OPERATION Sections 3 through 8 of this manual describe the operation of the American Megatrends AMIBIOS and the AMIBIOS Setup Utility. Refer to Running AMIBIOS Setup later in this chapter for standard Setup screens, options and defaults. The available Setup screens, options and defaults may vary if you have a custom BIOS. When the system is powered on, AMIBIOS performs the Power-On Self Test (POST) routines. These routines are divided into two phases: 1) System Test and Initialization. Test and initialize system boards for normal operations. 2) System Configuration Verification. Compare defined configuration with hardware actually installed. If an error is encountered during the diagnostic tests, the error is reported in one of two different ways. If the error occurs before the display device is initialized, a series of beeps is transmitted. If the error occurs after the display device is initialized, the error message is displayed on the screen. See BIOS Errors later in this section for more infor- mation on error handling. The following are some of the Power-On Self Tests (POSTs) which are performed when the system is powered on: • CMOS Checksum Calculation • Keyboard Controller Test • CMOS Shutdown Register Test • 8254 Timer Test • Memory Refresh Test • Display Memory Read/Write Test • Display Type Verification • Entering Protected Mode • Memory Size Calculation • Conventional and Extended Memory Test • DMA Controller Tests • Keyboard Test • System Configuration Verification and Setup _______________________________________________________________________ NOTE: When you perform a warm boot by pressing + + , all memory tests are bypassed. _______________________________________________________________________ AMIBIOS checks system and cache memory and reports them on both the initial AMIBIOS screen and the AMIBIOS System Configuration screen which appears after POST is completed. AMIBIOS attempts to initialize the peripheral devices by verifying TRENTON Technology Inc. 3-1 System BIOS CBI/CGI Technical Reference the validity of the system setup information stored in the system CMOS RAM. (See Running AMIBIOS Setup later in this chapter.) If AMIBIOS detects a fault, the screen displays the error condition(s) which has/have been detected. If no errors are detected, AMIBIOS attempts to load the system from any bootable device, such as a floppy disk or hard disk. Normally, the only POST routine visible on the screen is the memory test. The following screen displays when the system is powered on: AMIBIOS (C)1998 American Megatrends Inc. TRENTON Technology Inc. Hit DEL if you want to run SETUP Initial Power-On Screen You have two options: • Press to access the AMIBIOS Setup Utility. This option allows you to change various system parameters such as date and time, disk drives, etc. The Running AMIBIOS Setup section of this manual describes the options available. You may be requested to enter a password before gaining access to the AMIBIOS Setup Utility. (See Password Entry later in this section.) If you enter the correct password or no password is required, the AMIBIOS Setup Main Menu displays. (See Running AMIBIOS Setup later in this section.) • Allow the bootup process to continue without invoking the AMIBIOS Setup Utility. In this case, after AMIBIOS loads the system, you may be requested to enter a password. (See Password Entry later in this section.) Once the POST routines complete successfully, a screen displays showing the current configuration of your system, including processor type, base and extended memory amounts, floppy and hard drive types, display type and peripheral ports. In systems with more than 1MB, AMIBIOS reports 384KB less RAM than it finds, because it accounts for the address space between 640K and 1024K which is unavailable to DOS. This space is used for video RAM, video BIOS, system BIOS and adapter ROMs. 3-2 TRENTON Technology Inc. CBI/CGI Technical Reference System BIOS Password Entry The system may be configured so that the user is required to enter a password each time the system boots or whenever an attempt is made to enter AMIBIOS Setup. The password function may also be disabled so that the password prompt does not appear under any circumstances. The Password Check option in the Advanced CMOS Setup program allows you to specify when the password prompt displays: Always or only when Setup is attempted. The supervisor and user passwords may be changed using the Change Supervisor Password and Change User Password options on the AMIBIOS Setup Main Menu. If the passwords are null, the password prompt does not display at any time. A more detailed description of the password setup function may be found in the Running AMIBIOS Setup section later in this chapter. When password checking is enabled, the following password prompt displays: Enter CURRENT Password: Type the password and press . _______________________________________________________________________ NOTE: The null password is the system default and is in effect if a password has not been assigned or if the CMOS has been corrupted. In this case, the password prompt does not display. To set up passwords, you may use the Change Supervisor Password and Change User Password options on the AMIBIOS Setup Main Menu. (See Running AMIBIOS Setup later in this chapter.) _______________________________________________________________________ If an incorrect password is entered, the following screen displays: Enter CURRENT Password: X Enter CURRENT Password: TRENTON Technology Inc. 3-3 System BIOS CBI/CGI Technical Reference You may try again to enter the correct password. If you enter the password incorrectly three times, the system responds in one of two different ways, depending on the value specified in the Password Check option on the Advance CMOS Setup screen: 1) If the Password Check option is set to Setup, the system does not let you enter Setup, but does continue the booting process. You must reboot the system manually to retry entering the password. 2) If the Password Check option is set to Always, the system locks and you must reboot. After rebooting, you will be requested to enter the password. Once the password has been entered correctly, you are allowed to continue. BIOS Errors If an error is encountered during the diagnostic checks performed when the system is powered on, the error is reported in one of two different ways: 1) If the error occurs before the display device is initialized, a series of beeps is transmitted. 2) If the error occurs after the display device is initialized, the screen displays the error message. In the case of a non-fatal error, a prompt to press the key may also appear on the screen. Explanations of the beep codes and BIOS error messages may be found in Appendix A - BIOS Messages. As the POST routines are performed, test codes are presented on Port 80H. These codes may be helpful as a diagnostic tool and are listed in Appendix A - BIOS Messages. If certain non-fatal error conditions occur, you are requested to run the AMIBIOS Setup Utility. The error messages are followed by this screen: AMIBIOS (C)1998 American Megatrends, Inc. TRENTON Technology Inc. RUN SETUP UTILITY Press F1 to Resume Press . You may be requested to enter a password before gaining access to the AMIBIOS Setup Utility. (See Password Entry earlier in this section.) If you enter the correct password or no password is required, the AMIBIOS Setup Utility Main Menu displays. 3-4 TRENTON Technology Inc. CBI/CGI Technical Reference System BIOS RUNNING AMIBIOS Setup keeps a record of system parameters, such as date and time, disk drives, AMIBIOS SETUP display type and other user-defined parameters. The Setup parameters reside in the Read Only Memory Basic Input/Output System (ROM BIOS) so that they are available each time the system is turned on. AMIBIOS Setup stores the information in the comple- mentary metal oxide semiconductor (CMOS) memory. When the system is turned off, a backup battery retains system parameters in the CMOS memory. Each time the system is powered on, it is configured with these values, unless the CMOS has been corrupted or is faulty. The AMIBIOS Setup Utility is resident in the ROM BIOS so that it is available each time the computer is turned on. If, for some reason, the CMOS becomes corrupted, the system is configured with the default values stored in this ROM file. As soon as the system is turned on, the power-on diagnostic routines check memory, attempt to prepare peripheral devices for action, and offer you the option of pressing to run AMIBIOS Setup. If certain non-fatal errors occur during the Power-On Self Test (POST) routines which are run when the system is turned on, you may be prompted to run AMIBIOS Setup by pressing .

This function is described later in this chapter. 3-10 TRENTON Technology Inc. CBI/CGI Technical Reference System BIOS AUTO-DETECT The Auto-Detect Hard Disks option allows you to have AMIBIOS automatically detect HARD DISKS the type of hard disk drive(s) in your system. The automatic detection functions only if you have IDE drives. The parameters are reported on the Standard CMOS Setup screen. AMIBIOS searches first for the primary master and slave hard disk drives, then for the secondary master and slave drives. If it can access a drive, it reads the disk parameters. It then searches the AMIBIOS drive type table for matching parameters to determine the disk type and displays both the type and parameters on the screen. If no matching parameters are found in the table, AMIBIOS specifies the type as "User" and fills in the parameter values it found on the drive. If it cannot access the drive or if it is not an IDE drive, AMIBIOS times out and specifies that the disk drive is "Not Installed." _______________________________________________________________________ NOTE: The auto detect feature displays disk parameter values as established by the drive manufacturer. If the drive has been formatted using any other values, accepting the auto detect values will cause erratic behavior. You must either reformat the drive to meet the manufacturer's specifications or use Standard CMOS Setup to enter parameters which match the current format of the drive. _______________________________________________________________________ If you do not want to accept the hard disk type and its associated parameters as reported by AMIBIOS or if the drive is "Not Installed," you may use Standard CMOS Setup to set up the correct parameters for the drive. Once the parameters are correct for all of the drives, you may exit from the Standard CMOS Setup screen and save the settings in the CMOS. CHANGE AMIBIOS Setup has an optional password feature which can be configured so that a PASSWORD password must be entered each time the system boots or just when a user attempts to enter AMIBIOS Setup. (See the Advanced CMOS Setup section of this manual for infor- mation on how to enable the Password Check option.) The Change Supervisor Password and Change User Password options on the AMIBIOS Setup Main Menu allow you to establish passwords, change the current passwords or disable the password prompts by entering null passwords. The passwords are stored in CMOS RAM. The Change User Password function is accessible only if the supervisor password has been established previously. If you have signed on under the user password, you cannot change the supervisor password. _______________________________________________________________________ NOTE: The null password is the system default and is in effect if a password has not been assigned or if the CMOS has been corrupted. In this case, the "Enter CURRENT Password" prompt is bypassed when you boot the system, and you must establish a new password. _______________________________________________________________________ CHANGE If you select the Change Supervisor Password option, the following window displays: SUPERVISOR PASSWORD Enter new supervisor password: _ TRENTON Technology Inc. 3-11 System BIOS CBI/CGI Technical Reference This is the message which displays before you have established a password or if the last password entered was the null password. If a password has already been established, you are asked to enter the current password before being prompted to enter the new password. Type the new password and press . The password cannot exceed six (6) characters in length. The screen does not display the characters as you type them. After you have entered the new password, the following window displays: Retype new supervisor password: _ Re-key the new password as described above. If the password confirmation is miskeyed, AMIBIOS Setup displays the following message: Incorrect password, press any key to continue No retries are permitted; you must restart the procedure from the AMIBIOS Setup Main Menu. If the password confirmation is entered correctly, the following message displays: New supervisor password installed, press any key to continue When you press any key, the screen returns to the AMIBIOS Setup Main Menu screen, which allows you to save the password change or exit from Setup without saving the new password. To save the new password in CMOS memory, be sure to select Save Settings and Exit. If you save the changes when you exit AMIBIOS Setup, the password is stored in CMOS RAM. The next time the system boots, you are prompted for the password if the password function is present and is enabled. (See Advanced CMOS Setup later in this manual for an explanation of how to enable password checking.) _______________________________________________________________________ NOTE: Be sure to keep a record of the new password each time it is changed. If you forget it, use the Password Clear jumper to reset it to the default (null password). See the Specifications chapter of this manual for details. _______________________________________________________________________ CHANGE USER The Change User Password function is accessible only if the supervisor password has PASSWORD been established previously. 3-12 TRENTON Technology Inc. CBI/CGI Technical Reference System BIOS The Change User Password option is similar in functionality to the Change Supervisor Password and displays the same messages, except that "user" replaces "supervisor." If you have signed on under the user password, you cannot change the supervisor password. DISABLING THE To disable password checking so that the password prompt does not appear under any PASSWORD(S) circumstances, you may create null passwords using the Change Supervisor Password and Change User Password functions by pressing without typing in a new password. You will be asked to confirm the password. Select again and the following message displays: Supervisor password disabled, press any key to continue When you press any key, the screen returns to the AMIBIOS Setup Main Menu, which allows you to save the password change or exit from Setup without saving the null password. To save the null password(s) in CMOS memory, be sure to select Save Settings and Exit. AUTO Each AMIBIOS Setup option has two default settings (Optimal and Fail Safe). These CONFIGURATION settings can be applied to all AMIBIOS Setup options when you select the appropriate OPTIONS auto configuration option from the AMIBIOS Setup Main Menu. You can use these auto configuration options to quickly set the system configuration parameters which should provide the best performance characteristics, or you can select a group of settings which have a better chance of working when the system is having configuration-related problems. Auto Configuration with Optimal Settings This option allows you to load the Optimal default settings. These settings are best-case values which should provide the best performance characteristics. If CMOS RAM is corrupted, the Optimal settings are loaded automatically. If you select the Auto Configuration with Optimal Settings option, the following window displays: Load high performance settings (Y/N) ? N You have two options: • Press 'N' and to leave the current values in effect. • Press 'Y' and to load the Optimal default settings. TRENTON Technology Inc. 3-13 System BIOS CBI/CGI Technical Reference Auto Configuration with Fail Safe Settings This option allows you to load the Fail Safe default settings when you cannot boot your computer successfully. These settings are more likely to configure a workable computer. They may not provide optimal performance, but are the most stable settings. You may use this option as a diagnostic aid if your system is behaving erratically. Select the Fail Safe settings and then try to diagnose the problem after the computer boots. If you select the Auto Configuration with Fail Safe Settings option, the following window displays: Load failsafe settings (Y/N) ? N You have two options: • Press 'N' and to leave the current values in effect. • Press 'Y' and to load the Fail Safe default settings. SAVE SETTINGS The features selected and configured in the Setup screens are stored in the CMOS when AND EXIT this option is selected. The CMOS checksum is calculated and written to the CMOS. Control is then passed back to the AMIBIOS and the booting process continues, using the new CMOS values. If you select the SAVE SETTINGS AND EXIT option, the following window displays: Save current settings and exit (Y/N) ? Y You have two options: • Press 'N' and to return to the AMIBIOS Setup Main Menu. • Press 'Y' and to save the system parameters and continue with the booting process. EXIT WITHOUT This option passes control back to AMIBIOS without writing any changes to the CMOS. SAVING If you select the EXIT WITHOUT SAVING option, the following window displays: Quit without saving the current settings (Y/N) ? N You have two options: • Press 'N' and to return to the AMIBIOS Setup Main Menu. • Press 'Y' and to continue with the booting process without saving any system parameters. 3-14 TRENTON Technology Inc.

Primary and Secondary Hard Disk Drives The SBC supports up to four hard disk drives through a primary and secondary controller in a master/slave configuration. The primary controller uses I/O port addresses 1F0H 4-2 TRENTON Technology Inc. CBI/CGI Technical Reference Standard CMOS Setup through 1F7H, 3F6H and IRQ14. The secondary controller uses I/O port addresses 170H through 177H, 376H and IRQ15. The AMIBIOS enhanced IDE (EIDE) interface can support IDE Type 4 disk drives. This EIDE interface allows disk drives greater than 528MB to be used. The hard disk drives can be detected automatically by AMIBIOS (if they are IDE drives) or can be defined manually by the user, as described below. The Setup screen displays the system options: Pri Master: Auto Pri Slave: Auto Sec Master: Auto Sec Slave: Auto The Help window displays: 1-46: Predefined types USER: Enter parameters manually AUTO: Set parameters automatically on each boot CD-ROM: Use for ATAPI CD-ROM drives Or press ENTER to set all HDD parameters automatically To set up the hard disk drive parameter(s), use the plus (+) key or PgDn key to scroll through the drive types to locate the correct type of disk drive(s) in your computer. As you scroll through the disk types, the drive Type displays, along with values for size, cylinders, heads, write precompensation and sectors. Available predefined hard disk drive types are listed at the end of this section. If the parameters supplied by the manufacturer of your disk drive do not match any of these preprogrammed drive types, you may have AMIBIOS detect the drive type automatically (if it is an IDE drive), or you may select the User drive type to enter the parameters manually as described below. Set the drive type to CD-ROM to boot from a CD-ROM drive. Not Installed is available for use as an option. This option can be used for diskless work stations. Automatic Detection of Drive Type If any of the hard disks are IDE drives, AMIBIOS can automatically configure the drive type by detecting the IDE drive parameters and reporting them on the Standard CMOS Setup screen. You may invoke automatic detection of IDE drives in one of three ways: • Press Enter when the cursor is in the Type field. AMIBIOS detects the drive type and parameters as requested. If the drive type is not defined in the drive type table, this option displays User as the drive type and displays the parameters which were detected by AMIBIOS. The detected drive type values may then be saved in the CMOS. TRENTON Technology Inc. 4-3 Standard CMOS Setup CBI/CGI Technical Reference • Set the drive type to Auto to have AMIBIOS detect the drive type and parameters automatically each time the system is booted up. This option does not display the drive type on the Standard CMOS Setup screen, but does display it on the System Configuration screen shown after a successful bootup. • Select the Auto-Detect Hard Disks option on the AMIBIOS Setup Main Menu to have AMIBIOS automatically detect the type and parameters of each hard drive and place the information into the Standard CMOS Setup screen. The detected drive type values may then be saved in the CMOS. This option is described in the Running AMIBIOS Setup section of the System BIOS chapter of this manual. _______________________________________________________________________ NOTE: The auto detect feature displays disk parameter values as established by the drive manufacturer. If the drive has been formatted using any other values, accepting the auto detect values will cause erratic behavior. You must either reformat the drive to meet the manufacturer's specifications or use the User type to enter parameters which match the current format of the drive. _______________________________________________________________________ User-Defined Drive Types If the parameters supplied by the manufacturer of your disk drive do not match any of the preprogrammed drive types provided by AMIBIOS, you may enter the parameters manually. The user-defined parameters for each of the four drives may be different, which effec- tively allows four different user-definable hard disk types. Scroll to the end of the drive type list to the User type. You can manually enter the Cyln, Head, WPcom and Sec parameters. The Size parameter is automatically calculated and displayed by the system based on the other parameters entered. Use the arrow keys or tab key to move between fields. Once you have placed the cursor in a field, type in the correct value. The following explains the drive parameters which you must enter for a drive type which is not in the list: Type is the numeric designation for a drive with certain identification param- eters. Cylinders (Cyln) is the number of disk cylinders found in the specified drive type. Heads (Head) is the number of disk heads found in the specified drive type. Write Precompensation (WPcom) is the read delay circuitry which takes into account the timing differences between the inner and outer edges of the surface of the disk. The size of the sector gets progressively smaller as the track diameter diminishes. Yet each sector must still hold 512 bytes. Write precom- pensation circuitry on the hard disk compensates for the physical difference in 4-4 TRENTON Technology Inc. CBI/CGI Technical Reference Standard CMOS Setup sector size by boosting the write current for sectors on inner tracks. This parameter designates the track (cylinder) number where write precompensation begins. Sectors (Sec) designates the number of disk sectors per track. Size is the formatted capacity of the drive (in megabytes) based on the following formula: # of heads x # of cylinders x # of sects/cyln x 512 bytes/sect IDE Drive Type Setup Options For each of the four hard disk drives which is an IDE drive, the following options are also available for the drive: Logical Block Addressing (LBA) Mode This option allows you to enable IDE LBA (Logical Block Addressing) Mode for the specified primary or secondary IDE drive. Data is accessed by block addresses rather than by the traditional cylinder-head-sector format. This allows you to use drives larger than 528MB. If LBA Mode is set to On and is supported by the hard disk drive, and if the drive is formatted, AMIBIOS enables LBA mode and translates the physical parameters of the drive to logical parameters. If a hard disk drive which supports LBA mode and has a capacity greater than 528MB was formatted with LBA mode disabled, AMIBIOS does not enable LBA mode even if the LBA Mode parameter is set to On in Standard CMOS Setup. If LBA Mode is set to Off, AMIBIOS uses the physical parameters of the hard disk and does not translate parameters. The operating system which uses the parameter table then sees only 528MB of hard disk space even if the drive contains more than 528MB. Available options are: Off On Block (Blk) Mode This option supports transfer of multiple sectors to and from the specified primary or secondary IDE drive. Block mode boosts IDE drive performance by increasing the amount of data transferred during an interrupt. Block mode allows transfers of up to 64KB per interrupt, whereas only 512 bytes of data can be transferred per interrupt if block mode is not used. If Block Mode is set to On and is supported by the IDE drive, AMIBIOS enables multi- sector transfers. AMIBIOS sets the number of sectors to be transferred per interrupt to the value returned by the "identify drive" command. TRENTON Technology Inc. 4-5 Standard CMOS Setup CBI/CGI Technical Reference Available options are: Off On Programmed I/O (PIO) Mode IDE PIO mode programs timing cycles between the IDE drive and the programmable IDE controller. As the PIO mode increases, the cycle time decreases. Set the PIO Mode option to Auto to have AMIBIOS select the PIO mode used by the IDE drive being configured. If you select a specific value for the PIO mode, you must make absolutely certain that you are selecting the PIO mode supported by the IDE drive being configured. Available options are: Auto 03 14 25 32Bit Mode Hard disk drives connected to the SBC via the ISA Bus transfer data 16 bits at a time. An IDE drive on the PCI Local Bus can use a 32-bit data path. If the 32Bit Mode parameter is set to On, AMIBIOS enables 32-bit data transfers. If the host controller does not support 32-bit transfer, this feature must be disabled. Available options are: Off On BOOT SECTOR This option allows you to request AMIBIOS to issue a warning when any program or VIRUS PROTECTION virus issues a Disk Format command or attempts to write to the boot sector of the hard disk drive. The Setup screen displays the system option: Boot Sector Virus Protection Disabled Available options are: Disabled Enabled If the Boot Sector Virus Protection option is set to Enabled, the following message displays when a write is attempted to the boot sector. Boot Sector Write!!! Possible VIRUS: Continue (Y/N)? 4-6 TRENTON Technology Inc. CBI/CGI Technical Reference Standard CMOS Setup Select ‘Y’ or ‘N’ as appropriate. You may have to select ‘N’ several times to prevent the boot sector write. The following message displays if any attempt is made to format any cylinder, head or sector of any hard disk drive via the BIOS INT 13 Hard Disk Drive Service: Format!!! Possible VIRUS: Continue (Y/N)? Select ‘Y’ or ‘N’ as appropriate. If you select ‘Y’ to continue, formatting proceeds normally. If you do not want to continue formatting, you may have to select ‘N’ several times, depending on how many retries are performed by the upper-level software. For example, DOS does at least five retries before the Format utility is actually terminated. _______________________________________________________________________ NOTE: You should not enable boot sector virus protection when formatting a hard drive. _______________________________________________________________________ The DOS hard disk Format utility does not use INT 13H function AH=05H to format the hard disk. It only verifies the hard disk using the INT 13H Verify function (AH=04H). The virus warning message is not displayed during DOS hard disk drive formatting.

Once values have been defined, they display each time Peripheral Setup is run. The AMIBIOS allows automatic or manual setup of peripheral devices. The floppy drive controller, serial port, parallel port and IDE controller options on the Peripheral Setup screen can each be set to Auto, which causes AMIBIOS to configure the periph- erals automatically as described under each heading below. When you set these options to values other than Auto, the values you set up manually are used by AMIBIOS when booting the system. AMIBIOS reports any I/O conflicts after displaying the BIOS Configuration Summary screen. TRENTON Technology Inc. 8-1 Peripheral Setup CBI/CGI Technical Reference OnBoard FDC The on-board floppy drive controller may be enabled or disabled using this option. When this option is set to Auto, AMIBIOS attempts to enable any floppy drive controller on the ISA Bus. If no floppy controller is found on the ISA Bus, the on-board floppy controller is enabled. The Setup screen displays the system option: OnBoard FDC Auto Available options are: Auto Disabled Enabled OnBoard Serial Port 1/OnBoard Serial Port 2 Each of these options enables the specified serial port on the SBC and establishes the base I/O address for the port. The Setup screen displays the system options: OnBoard Serial Port1 Auto OnBoard Serial Port2 Auto Available options are: Auto Disabled 3F8H 2F8H 3E8H 2E8H When this option is set to Auto, AMIBIOS also attempts to avoid address conflicts. If the off-board serial ports are configured to specific starting I/O ports via jumper settings, AMIBIOS configures the on-board serial ports to avoid conflicts. AMIBIOS checks the ISA Bus for serial ports. Any off-board serial ports found on the ISA Bus are left at their assigned addresses. Serial Port 1, the first on-board serial port, is configured with the first available address and Serial Port 2, the second on-board serial port, is configured with the next available address. The default address assignment order is 3F8H, 2F8H, 3E8H, 2E8H. Note that this same assignment order is used by AMIBIOS to place the active serial port addresses in lower memory (BIOS data area) for configuration as logical COM devices. After all addresses have been assigned, any remaining on-board serial ports are disabled. 8-2 TRENTON Technology Inc. CBI/CGI Technical Reference Peripheral Setup For example, if there is one off-board serial port on the ISA Bus and its address is set to 2F8H, Serial Port 1 is assigned address 3F8H and Serial Port 2 is assigned address 3E8H. Configuration is then as follows: COM1 - Serial Port 1 (at 3F8H) COM2 - off-board serial port (at 2F8H) COM3 - Serial Port 2 (at 3E8H) OnBoard Parallel Port This option enables the parallel port on the SBC and establishes the base I/O address for the port. The Setup screen displays the system option: OnBoard Parallel Port Auto Available options are: Auto Disabled 378 278 3BC When this option is set to Auto, AMIBIOS checks the ISA Bus for off-board parallel ports. Any parallel ports found on the ISA Bus are left at their assigned addresses. The on-board Parallel Port is automatically configured with the first available address not used by an off-board parallel port. The default address assignment order is 3BCH, 378H, 278H. Note that this same assignment order is used by AMIBIOS to place the active parallel port addresses in lower memory (BIOS data area) for configuration as logical LPT devices. Parallel Port Mode This option specifies the parallel port mode. ECP and EPP are both bidirectional data transfer schemes which adhere to the IEEE P1284 specifications. The Setup screen displays the system option: Parallel Port Mode ECP Three options are available: • Normal uses normal parallel port mode. • EPP allows the parallel port to be used with devices which adhere to the Enhanced Parallel Port (EPP) specification.

CBI/CGI Technical Reference Appendix A BIOS Messages BIOS BEEP CODES Errors may occur during the POST (Power-On Self Test) routines which are performed each time the system is powered on. Non-fatal errors are those which, in most cases, allow the system to continue the bootup process. The error message normally appears on the screen. See BIOS Error Messages later in this appendix for descriptions of these messages. Fatal errors are those which will not allow the system to continue the bootup procedure. These fatal errors are usually communicated through a series of audible beeps. Each error message has its own specific beep code, defined by the number of beeps following the error detection. The following table lists the errors which are communicated audibly. All errors listed, with the exception of #8, are fatal errors. Beep Count Message Description 1 Refresh Failure The memory refresh circuitry of the processor board is faulty. 2 Parity Error A parity error was detected in the base memory (the first block of 64KB) of the system. 3 Base 64KB Memory A memory failure occurred within the first 64KB Failure of memory. 4 Timer Not Operational A memory failure occurred within the first 64KB of memory, or Timer #1 on the processor board has failed to function properly. 5 Processor Error The CPU (Central Processing Unit) on the processor board has generated an error. 6 8042 - Gate A20 Failure The keyboard controller (8042) contains the Gate A20 switch which allows the processor to operate in protected mode. This error message means that the BIOS is not able to switch the processor into protected mode. 7 Processor Exception The processor on the SBC has generated an Interrupt Error exception interrupt. 8 Display Memory The system video adapter is either missing or Read/Write Error its memory is faulty.

For additional options, you may: • Select Boot Device Options to display and/or change boot device settings. • Select SCSI Device Configuration to display and/or change the individual settings for the devices attached to the host adapter. • Select Advanced Configuration Options to display and/or change the advanced configuration settings for the host adapter. Host Adapter SCSI ID Each device on the SCSI bus, including the adapter, must have a unique SCSI ID. Allowable IDs are 0 through 7 on 8-bit adapters, and 0 through 15 on 16-bit adapters. The SCSI ID serves two purposes: 1) It uniquely defines each SCSI device on the bus. 2) It determines which device controls the bus when two or more devices try to use the bus at the same time. For 8-bit devices, SCSI ID 7 has the highest C-4 TRENTON Technology Inc. CBI/CGI Technical Reference priority and SCSI ID 0 has the lowest priority. For 16-bit devices, the priority of IDs is 7 through 0, then 15 through 8,with SCSI ID 7 having the highest priority and SCSI ID 8 having the lowest priority. All adapters (8-bit and 16-bit) have a default SCSI ID of 7, which gives the host adapter the highest priority on the SCSI bus. Available options are: 8-bit Adapters: 0 through 7 16-bit Adapters: 0 through 15 SCSI Parity Checking Each adapter uses SCSI parity checking to verify the accuracy of data transfer on the SCSI bus. By default, parity checking is set to Enabled. Most currently available SCSI devices support SCSI parity. However, if a device on the SCSI bus does not support SCSI parity, set the SCSI Parity Checking option to Disabled. Available options are: Enabled Disabled Host Adapter SCSI Termination A set of resistors, called terminators, must be either installed in or enabled on the first and last SCSI devices on each SCSI bus; otherwise, the devices will not operate properly. Because the adapter is usually the SCSI device at one end of the bus, adapter termination for an 8-bit adapter is set to Enabled by default. If an 8-bit adapter is not at the end of the SCSI bus, set the Host Adapter SCSI Termination option to Disabled. On 16-bit adapters, termination is enabled for both the low byte (bits 0-7) and the high byte (bits 8-15). The table on the next page shows appropriate termination settings for a 16-bit adapter: Available options are: 8-bit Adapters: Enabled Disabled 16-bit Adapters: Low ON/High ON Low OFF/High OFF Low OFF/High ON TRENTON Technology Inc. C-5 CBI/CGI Technical Reference Description Termination Adapter is at end of SCSI bus; bus has only Low ON/High ON 8-bit devices or only 16-bit devices (default) Adapter is at end of SCSI bus; bus has both Low ON/High ON 8-bit and 16-bit devices. Last device must be 16-bit and be terminated. Adapter is not at end of SCSI bus; bus has Low OFF/High OFF only 16-bit devices.

If you do not know the SCSI ID of the device you want to configure, press until the Options Menu displays, and then select the SCSI Disk Utilities option. A list of SCSI devices and their SCSI IDs displays. Note the ID of the device you want to configure and then return to the SCSI Device Configuration screen. SCSI DEVICE The settings for each SCSI device on the SCSI bus can be modified individually as SETTINGS described below. Initiate Sync Negotiation Synchronous negotiation is a SCSI feature that allows the SCSI adapter and its attached SCSI devices to transfer data in synchronous mode. Synchronous data transfer is faster than asynchronous data transfer. C-8 TRENTON Technology Inc. CBI/CGI Technical Reference The Initiate Sync Negotiation setting determines whether the adapter initiates synchronous negotiation with the SCSI device. If this option is set to the default setting of Yes, the adapter initiates synchronous negotiation with the SCSI device. Normally, you should leave this option set to Yes, because most SCSI devices support synchronous negotiation, which allows for faster data transfer. If a device does not support synchronous negotiation, the adapter automatically transfers the data in asynchronous mode. If you change the setting to No, the adapter does not initiate synchronous negotiation; however, the adapter always responds to synchronous negotiation if the SCSI device initiates it. If neither the adapter nor the SCSI device negotiates for synchronous data transfers, data is transferred in asynchronous mode. Available options are: Yes No Maximum Sync Transfer Rate This setting determines the maximum synchronous data transfer rate that the adapter will negotiate with the device. The adapter automatically negotiates for the rate requested by the device. The allowable maximum rates are in megabytes. If the adapter is set not to negotiate for synchronous data transfer (i.e., if the Initiate Sync Negotiation option is set to No), the value selected here is the maximum rate at which the adapter accepts data from the device during negotiation. This is standard SCSI protocol. If the Support for Ultra SCSI Speed option on the Advanced Configuration Options screen is disabled, the only values available for maximum sync transfer rate are those for 8-bit adapters (see below); in this case, the default is 20.0. If Support for Ultra SCSI Speed is enabled, the values for 16-bit adapters are available and the default is 40.0. Available options are: 8-bit Adapters: 20.0 16.0 13.4 10.0 16-bit Adapters: 40.0 32.0 26.8 20.0 Enable Disconnection This setting determines whether the adapter allows a SCSI device to disconnect from the SCSI bus (sometimes called Disconnect/Reconnect). Enabling disconnection allows the TRENTON Technology Inc. C-9 CBI/CGI Technical Reference adapter to perform other operations on the SCSI bus while the SCSI device is tempo- rarily disconnected. When the Enable Disconnection option is set to the default setting of Yes, the SCSI device may disconnect from the SCSI bus. The SCSI device may choose not to disconnect, however, even if permitted by the adapter (this can usually be configured on the SCSI device). When this option is set to No, the SCSI device cannot disconnect from the SCSI bus. Leave the Enable Disconnection option set to Yes if the adapter connects to two or more SCSI devices. This optimizes SCSI bus performance. If the adapter connects to only one SCSI device, set this option to No to achieve slightly better performance. Available options are: Yes No Initiate Wide Negotiation This option, which only displays for 16-bit adapters, lets the adapter initiate wide negoti- ation with a 16-bit SCSI device. The adapter will not attempt wide negotiation with 8-bit devices, so you can leave this option set to Yes even if the bus includes 8-bit devices. Available options are: Yes No Send Start Unit Command This setting determines whether the adapter sends the Start Unit command (SCSI command 1B) to the SCSI device. The default setting for Send Start Unit Command is No (disabled). Enabling this option reduces the load on a computer's power supply by allowing the adapter to turn on SCSI devices one by one when the computer boots; otherwise, all SCSI devices turn on at the same time. Before you enable this option for a device, make sure the AIC-7880 BIOS is enabled. Also, check the device documentation to make sure the device supports the command. On most devices, you must also change a switch or jumper setting on the device to enable the device to respond to the command. If you enable Send Start Unit Command for more than one SCSI device, the adapter first sends the Start Unit command to the boot device specified in the Boot Target ID option of the Boot Device Configuration screen. When the boot device responds, Start Unit commands are sent to the remaining devices, beginning with the device with the lowest SCSI ID. The boot time varies depending on how long each drive takes to spin up. C-10 TRENTON Technology Inc. CBI/CGI Technical Reference Available options are: Yes No Include in BIOS Scan This option indicates whether or not the specified SCSI device should be included in a scan of the devices which is done during bootup. Setting this option to No for devices which are not attached saves time during bootup since the BIOS will not spend time checking for unassigned devices. Available options are: Yes No TRENTON Technology Inc.

Plug and Play Scam Support When this option is set to Enabled, it allows the adapter to automatically assign a SCSI ID to an attached SCSI device that supports SCAM-1 (SCSI Configured AutoMatically) protocol. Most non-SCAM devices tolerate SCAM protocol, so you can usually enable this option even if you have some non-SCAM devices. In rare cases, an old SCSI-1 device may not tolerate SCAM and may cause your computer to hang or operate errati- cally. If this happens, set the option back to Disabled. The default for this option is Disabled. When you attempt to change it to Enabled, the following informational message displays: WARNING: ‘Reset SCSI Bus at IC Initialization’ cannot be DISABLED if ‘Plug and Play Scam Support’ is ENABLED. (Compliant to Scan Protocol) Available options are: Enabled Disabled C-12 TRENTON Technology Inc. CBI/CGI Technical Reference Reset SCSI Bus at IC Initialization The default for this option is Enabled. When the Plug and Play Scam Support option is set to Enabled, you cannot change this option to Disabled. Available options are: Enabled Disabled Host Adapter BIOS This option enables or disables the AIC-7880 BIOS. The BIOS must be enabled if you want the computer to boot from a SCSI hard disk drive connected to the adapter. In addition, the BIOS must be enabled if you want to enable any of the following options: • Support Removable Disks Under BIOS as Fixed Disks • Extended BIOS Translation for DOS Drives > 1 GByte • Multiple LUN Support • BIOS Support for Bootable CD-ROM • BIOS Support for Int 13 Extensions • Support for Ultra SCSI Speed • Send Start Unit SCSI Command If the devices on the SCSI bus are controlled by device drivers (and therefore do not need a BIOS), you can disable the AIC-7880 BIOS to free about 16KB of memory. This also shortens the boot time by up to 60 seconds. Available options are: Enabled Disabled Support Removable Disks Under BIOS as Fixed Disks This setting controls which removable-media drives are supported by the AIC-7880 BIOS. When you attempt to change the setting of this option, the following informational message displays: WARNING: Do not remove media from a removable media drive if it is under BIOS control. TRENTON Technology Inc. C-13 CBI/CGI Technical Reference Available options are: • Boot Only - Only the removable-media drive designated as the boot device is treated as a hard disk drive. This is the default option. • All Disks - All removable-media drives supported by the AIC-7880 BIOS are treated as hard drives. This setting has no effect on drives under NetWare, because NetWare automatically supports removable-media drives as fixed disks. • Disabled - No removable-media drives running under DOS are treated as hard disk drives. In this situation, driver software is needed, because the drives are not controlled by the BIOS. Extended BIOS Translation for DOS Drives > 1 GByte All current versions of MS-DOS are limited to 1024 cylinders per drive. The standard translation scheme for SCSI host adapters, using 64 heads and 32 sectors, provides a maximum accessible capacity of 1 GByte. To support disk drives larger than 1 GByte, the AIC-7880 BIOS includes an extended translation scheme that supports disk drives as large as 8 GBytes under MS-DOS. This option is not available if the Host Adapter BIOS option is set to Disabled. The default for this option is Enabled and should not be changed. With extended translation enabled, drives handled by the AIC-7880 BIOS use extended translation if their formatted capacity is greater than 1 GByte, and drives smaller than 1 GByte use standard translation. _______________________________________________________________________ NOTE: If you decide to change the translation scheme, be sure to back up the disk drives first. All data is erased when you change from one translation scheme to another. _______________________________________________________________________ When you partition a disk larger than 1 GByte, use the MS-DOS fdisk utility as you normally would. Because the cylinder size increases up to 8MB under extended trans- lation, the partition size you choose must be a multiple of 8MB. If you request a size that is not a multiple of 8MB, fdisk rounds up to the nearest whole multiple of 8MB. Available options are: Enabled Disabled Display Message During BIOS Initialization This option has no effect since the configuration utility is invoked using the cfg7880.exe program. Multiple LUN Support This option allows the BIOS to support multiple logical units. Set this option to Enabled if any devices have multiple logical units. C-14 TRENTON Technology Inc.

UTILITIES When you select SCSI Disk Utilities from the Options Menu, SCSISelect scans the SCSI bus for SCSI devices and displays a screen similar to the following: Adaptec AIC7880 Ultra/Ultra W < SCSISelect(TM) > Utility vX.XX AIC-7880 Ultra/Ultra W at Bus:Device XX:XXh Select SCSI Disk and press SCSI ID # 0: SEAGATE ST34371W SCSI ID # 1: No device SCSI ID # 2: No device SCSI ID # 3: No device SCSI ID # 4: No device SCSI ID # 5: No device SCSI ID # 6: No device SCSI ID # 7: AIC-7880 Ultra/Ultra W SCSI ID # 8: No device SCSI ID # 9: No device SCSI ID #10: No device SCSI ID #11: No device SCSI ID #12: No device SCSI ID #13: No device SCSI ID #14: No device SCSI ID #15: No device Arrow keys to move cursor, to select option, to exit (*=default) SCSI Disk Utilities Screen This screen lists the SCSI IDs on the SCSI bus and the types of devices assigned to each ID. If your system has an Ultra Wide SCSI adapter, 16 devices display (IDs 0 through 15). If you have an 8-bit adapter, only IDs 0 through 7 display. Select the device you wish to format or verify and press . If the device has multiple logical units, a menu of LUNs displays. Select the LUN of the unit you want to format or verify and press . The following menu displays: Format Disk Verify Disk Media Format Disk A disk must have a low-level format before you can use the operating system's parti- tioning and high-level formatting utilities, such as MS-DOS fdisk and format. Most C-16 TRENTON Technology Inc. CBI/CGI Technical Reference SCSI drives are preformatted and need not be formatted again. If a drive is not prefor- matted, you can use SCSISelect to perform a low-level format on the drive. The formatting is compatible with most SCSI disk drives. _______________________________________________________________________ NOTE: A low-level format destroys all data on the drive. Be sure to back up your data before performing this operation. You cannot abort a low-level format once it starts. _______________________________________________________________________ When you select the Format Disk option, a prompt displays showing the SCSI ID, type and size of the device you have selected and asks you to confirm that you want to format the disk: SCSI ID #0 : SEAGATE ST34371W Capacity: 4148 MBytes WARNING!!! This drive is about to be low-level formatted. All data on the disk will be erased. Format Disk? Yes No Two options are available: • Select Yes to start formatting the disk immediately. • Select No to cancel the format command without performing the format and return to the SCSI Disk Utilities screen. Verify Disk Media This option lets you scan a disk device for defects. If SCSISelect finds bad blocks, it prompts you to reassign them so they are no longer used. When you select the Verify Disk option, a prompt displays showing the SCSI ID, type and size of the device you have selected and asks you to confirm that you want to verify the disk: SCSI ID #0 : SEAGATE ST34371W Capacity: 4148 MBytes This drive will be scanned for media defects. All recoverable defects will be remapped. Verify Disk? Yes No TRENTON Technology Inc. C-17 CBI/CGI Technical Reference Two options are available: • Select Yes to continue with the verify procedure and reassign bad blocks. If you choose to perform the verify, SCSISelect notifies you of bad blocks and prompts you to reassign them.
