The board is designed to support the following: • Intel Pentium 4 processors in an mPGA478 processor socket with a 400/533/800 MHz system bus • Intel Celeron processors in an mPGA478 processor socket with a 400 MHz system bus See the Intel web site listed below for the most up-to-date list of supported processors. For information about Refer to Supported processors for the D865GVHZ board http://www.intel.com/design/motherbd/hz/hz_proc.htm CAUTION Use only the processors listed on web site above. Use of unsupported processors can damage the board, the processor, and the power supply. INTEGRATOR’S NOTES � • Use only ATX12V-, SFX12V-, or TFX12V-compliant power supplies with the Desktop Board D865GVHZ. ATX12V, SFX12V, and TFX12V power supplies have an additional power lead that provides required supplemental power for the processor. Always connect the 20-pin and 4-pin leads of ATX12V, SFX12V, and TFX12V power supplies to the corresponding connectors on the desktop board, otherwise the board will not boot. • Do not use a standard ATX power supply. The board will not boot with a standard ATX power supply. • Refer to Table 4 on page 21 for a list of supported system bus frequency and memory speed combinations. For information about Refer to Power supply connectors Section 2.8.2.3, page 65 20 Product Description 1.6 System Memory The Desktop Board D865GVHZ has two DIMM sockets and supports the following memory features: • 2.6 V (only) 184-pin DDR SDRAM DIMMs with gold-plated contacts • Unbuffered, single-sided or double-sided DIMMs with the following restriction: Double-sided DIMMS with x16 organization are not supported. • 2 GB maximum total system memory. • Minimum total system memory: 64 MB • Non-ECC DIMMs • Serial Presence Detect • DDR400, DDR333, and DDR266 SDRAM DIMMs Table 4 lists the supported system bus frequency and memory speed combinations. Table 4. Supported System Bus Frequency and Memory Speed Combinations To use this type of DIMM… The processor's system bus frequency must be… DDR400 800 MHz DDR333 (Note) 800 or 533 MHz DDR266 800, 533, or 400 MHz Note: When using an 800 MHz system bus frequency processor, DDR333 memory is clocked at 320 MHz. This minimizes system latencies to optimize system throughput. ✏ NOTES To be fully compliant with all applicable DDR SDRAM memory specifications, the board should be populated with DIMMs that support the Serial Presence Detect (SPD) data structure. This allows the BIOS to read the SPD data and program the chipset to accurately configure memory settings for optimum performance. If non-SPD memory is installed, the BIOS will attempt to correctly configure the memory settings, but performance and reliability may be impacted or the DIMMs may not function under the determined frequency.

DVMT ensures the most efficient use of available system memory for maximum 2-D/3-D graphics performance. Up to 64 MB of system memory can be allocated to DVMT on systems that have 256 MB or more of total system memory installed. Up to 32 MB can be allocated to DVMT on systems that have 128 MB but less than 256 MB of total installed system memory. Up to 8 MB can be allocated to DVMT when less than 128 MB of system memory is installed. DVMT returns system memory back to the operating system when the additional system memory is no longer required by the graphics subsystem. DVMT will always use a minimal fixed portion of system physical memory (as set in the BIOS Setup program) for compatibility with legacy applications. An example of this would be when using VGA graphics under DOS. Once loaded, the operating system and graphics drivers allocate additional system memory to the graphics buffer as needed for performing graphics functions. NOTE ✏ The use of DVMT requires operating system driver support. 1.7.1.4 Zone Rendering Technology (ZRT) The Intel Extreme Graphics 2 Controller supports Zone Rendering Technology (ZRT). ZRT is a process by which the screen is divided into several zones. Each zone is completely cached and rendered on chip before being written to the frame buffer. The benefits of ZRT include the following: • Increased memory efficiency via better localization of data • Increased on-chip processing speed due to decreased wait time for data • Increased effective pixel fill rates • Increased headroom for larger resolution and color depth • Reduced power as a result of decreased memory bandwidth • Reduction in depth and color bandwidth associated with conventional rendering 1.7.1.5 Rapid Pixel and Text Rendering (RPTR) The Rapid Pixel and Text Rendering Engine (RPTR) architecture utilizes special pipelines that allow 2D and 3D operations to overlap. By providing 8X compression, the RPTR engine reduces the memory bandwidth required to read texture memory, and reduces the amount of memory required for texture storage. A dedicated, non-blocking, multi-tier cache is provided for textures, colors, Z and vertex rendering. With single-pass, quad texture support, the drivers can submit up to four textures that pass to the graphics engine concurrently. The graphics core can switch between 2D and 3D operations without having to complete all operations of the same mode, which minimizes the overhead time required in switching between modes. A 2D Block Level Transfer (BLT) in the RPTR engine is extended to 256-bit, which supports fast blitter fill rate. This enables the blitter sequence of the same addresses to access the cache and offloads the memory bandwidth required to support blitter fill rate. Then the cache is emptied automatically when the sequence of operations are complete. 32 Product Description 1.7.1.6 Intelligent Memory Management (IMM) Intelligent Memory Management (IMM) technology is Intel’s unique UMA memory manager architecture, consisting of these key elements: • Tiled memory addressing capability • Deep display buffer implementation • Dynamic data management scheme The memory addressing allows address remapping in the hardware for all graphics surfaces including textures, frame buffer, Z buffer, and video surfaces. Deep display buffers and dedicated screen refreshes improve visual performance, while the dynamic data management scheme manages burst size and page closing policies for memory accesses. IMM reduces the aggregate processor latency and allows longer in-page bursts for higher system performance. IMM also increases page coherency and improves memory efficiency in texture loads, 2D blitters, color/Z, MPEG2 motion compression, and other operations. 1.7.1.7 Video Mixing Renderer (VMR) The Intel Extreme Graphics 2 controller features VMR technology. VMR is a process where various data types can be blended together before being displayed. VMR allows applications to bend and twist images such as 3D textures so that special effects such as wipes, spins, and fades can be achieved. 1.7.1.8 PC/VCR Time Shifted Viewing PC/VCR requires a TV-tuner add-in card and a third party application. PC/VCR time shifted viewing allows the user to view and digitally record video pictures on their PC. Users can view stored images while recording and by using time-shifted viewing they can pause, resume, replay, and catch up to real time. The Intel Pentium 4 processor in combination with the Intel 82865GV GMCH optimizes performance so that the video output is smooth without leaving any visual artifacts. Video tearing and corruption is prevented by the use of multiple buffers within the Intel Extreme Graphics 2 controller. 1.7.1.9 Bi-cubic Filtering Bi-cubic filtering is a new 4X4 filter that allows images to be generated more smoothly in the 3D pipeline. The bi-cubic filter can be used to improve image quality for all 3D texture engine components. 33 Intel Desktop Board D865GVHZ Technical Product Specification 1.7.2 USB The board supports up to eight USB 2.0 ports, supports UHCI and EHCI, and uses UHCI- and EHCI-compatible drivers. The ICH5 provides the USB controller for all ports. The port arrangement is as follows: • Two ports are implemented with stacked back panel connectors, adjacent to the PS/2 connectors • Two ports are implemented with stacked back panel connectors, adjacent to the audio connectors • Four ports are routed to two separate front panel USB connectors NOTE ✏ Computer systems that have an unshielded cable attached to a USB port may not meet FCC Class B requirements, even if no device is attached to the cable. Use shielded cable that meets the requirements for full-speed devices. For information about Refer to The location of the USB connectors on the back panel Figure 14, page 61 The location of the front panel USB connectors Figure 18, page 70 The EHCI, front panel, UHCI, and USB specifications Section 1.4, page 17 1.7.3 IDE Support The board provides four IDE interface connectors: • Two Parallel ATA IDE connectors, which support a total of four devices (two per connector) • Two Serial ATA IDE connectors, which support one device per connector 1.7.3.1 Parallel ATA IDE Interfaces The ICH5’s Parallel ATA IDE controller has two independent bus-mastering Parallel ATA IDE interfaces that can be independently enabled. The Parallel ATA IDE interfaces support the following modes: • Programmed I/O (PIO): processor controls data transfer. • 8237-style DMA: DMA offloads the processor, supporting transfer rates of up to 16 MB/sec. • Ultra DMA: DMA protocol on IDE bus supporting host and target throttling and transfer rates of up to 33 MB/sec. • ATA-66: DMA protocol on IDE bus supporting host and target throttling and transfer rates of up to 66 MB/sec. ATA-66 protocol is similar to Ultra DMA and is device driver compatible. • ATA-100: DMA protocol on IDE bus allows host and target throttling. The ICH5’s ATA-100 logic can achieve read transfer rates up to 100 MB/sec and write transfer rates up to 88 MB/sec. ✏ NOTE ATA-66 and ATA-100 are faster timings and require a specialized cable to reduce reflections, noise, and inductive coupling. 34 Product Description The Parallel ATA IDE interfaces also support ATAPI devices (such as CD-ROM drives) and ATA devices using the transfer modes listed in Section 4.4.4.1 on page 106. The BIOS supports Logical Block Addressing (LBA) and Extended Cylinder Head Sector (ECHS) translation modes. The drive reports the transfer rate and translation mode to the BIOS. The Desktop Board supports Laser Servo (LS-120) diskette technology through the Parallel ATA IDE interfaces. An LS-120 drive can be configured as a boot device by setting the BIOS Setup program’s Boot menu to one of the following: • ARMD-FDD (ATAPI removable media device – floppy disk drive) • ARMD-HDD (ATAPI removable media device – hard disk drive) For information about Refer to The location of the Parallel ATA IDE connectors on the D865GVHZ board Figure 17, page 68 1.7.3.2 Serial ATA Interfaces The ICH5’s Serial ATA controller offers two independent Serial ATA ports with a theoretical maximum transfer rate of 150 MB/s per port. One device can be installed on each port for a maximum of two Serial ATA devices. A point-to-point interface is used for host to device connections, unlike Parallel ATA IDE which supports a master/slave configuration and two devices per channel. For compatibility, the underlying Serial ATA functionality is transparent to the operating system. The Serial ATA controller can operate in both legacy and native modes. In legacy mode, standard IDE I/O and IRQ resources are assigned (IRQ 14 and 15). In Native mode, standard PCI resource steering is used. Native mode is the preferred mode for configurations using the Windows XP and Windows 2000 operating systems. NOTE ✏ Many Serial ATA drives use new low-voltage power connectors and require adaptors or power supplies equipped with low-voltage power connectors.

Table 16. Wake-up Devices and Events These devices/events can wake up the computer… …from this state (Note) LAN S1, S3, S4, S5 Modem (back panel Serial Port A) S1, S3 (Note) PME# signal S1, S3, S4, S5 Power switch S1, S3, S4, S5 PS/2 devices S1, S3 RTC alarm S1, S3, S4, S5 USB S1, S3 Note: For LAN and PME# signal, S5 is disabled by default in the BIOS Setup program. Setting this option to Power On will enable a wake-up event from LAN in the S5 state. NOTE ✏ The use of these wake-up events from an ACPI state requires an operating system that provides full ACPI support. In addition, software, drivers, and peripherals must fully support ACPI wake events. 47 Intel Desktop Board D865GVHZ Technical Product Specification 1.12.2 Hardware Support CAUTION Ensure that the power supply provides adequate +5 V standby current if LAN wake capabilities and Instantly Available PC technology features are used. Failure to do so can damage the power supply. The total amount of standby current required depends on the wake devices supported and manufacturing options. The Desktop Board D865GVHZ provide several power management hardware features, including: • Power connector • Fan connectors • LAN wake capabilities • Instantly Available PC technology • Resume on Ring • Wake from USB • Wake from PS/2 keyboard • PME# signal wake-up support LAN wake capabilities and Instantly Available PC technology require power from the +5 V standby line. The sections discussing these features describe the incremental standby power requirements for each. Resume on Ring enables telephony devices to access the computer when it is in a power-managed state. The method used depends on the type of telephony device (external or internal). NOTE ✏ The use of Resume on Ring and Wake from USB technologies from an ACPI state requires an operating system that provides full ACPI support. 1.12.2.1 Power Connector ATX12V-, SFX12V-, and TFX12V-compliant power supplies can turn off the system power through system control. When an ACPI-enabled system receives the correct command, the power supply removes all non-standby voltages. When resuming from an AC power failure, the computer returns to the power state it was in before power was interrupted (on or off). The computer’s response can be set using the Last Power State feature in the BIOS Setup program’s Boot menu. For information about Refer to The location of the power connector Figure 15, page 63 The signal names of the power connector Table 32, page 66 The BIOS Setup program’s Boot menu Table 74, page 119 The ATX12V, SFX12V, and TFX12V specifications Section 1.4, page 17 48 Product Description 1.12.2.2 Fan Connectors Table 17 summarizes the function/operation of the fan connectors. Table 17. Fan Connector Function/Operation Connector Description Processor fan • +12 V DC connection for a processor fan or active fan heatsink. • Fan is on in the S0 or S1 state.

Failure to provide adequate standby current when implementing LAN wake capabilities can damage the power supply. LAN wake capabilities enable remote wake-up of the computer through a network. The LAN subsystem PCI bus network adapter monitors network traffic at the Media Independent Interface. Upon detecting a Magic Packet* frame, the LAN subsystem asserts a wake-up signal that powers up the computer. Depending on the LAN implementation, the Desktop Board D865GVHZ supports LAN wake capabilities with ACPI in the following ways: • The PCI bus PME# signal for PCI 2.2 compliant LAN designs • The onboard LAN subsystem 49 Intel Desktop Board D865GVHZ Technical Product Specification 1.12.2.4 Instantly Available PC Technology CAUTION For Instantly Available PC technology, the +5 V standby line for the power supply must be capable of providing adequate +5 V standby current. Failure to provide adequate standby current when implementing Instantly Available PC technology can damage the power supply. Instantly Available PC technology enables the Desktop Board D865GVHZ to enter the ACPI S3 (Suspend-to-RAM) sleep-state. While in the S3 sleep-state, the computer will appear to be off (the power supply is off, and the front panel LED is amber if dual colored, or off if single colored.) When signaled by a wake-up device or event, the system quickly returns to its last known wake state. Table 16 on page 47 lists the devices and events that can wake the computer from the S3 state. The Desktop Board D865GVHZ supports the PCI Bus Power Management Interface Specification. For information on the version of this specification, see Section 1.4. Add-in boards that also support this specification can participate in power management and can be used to wake the computer. The use of Instantly Available PC technology requires operating system support and PCI 2.2 compliant add-in cards and drivers. 50 Product Description 1.12.2.5 +5 V Standby Power Indicator LED The +5 V standby power indicator LED shows that power is still present even when the computer appears to be off. Figure 13 shows the location of the standby power indicator LED on the D865GVHZ board.

The PCI specification specifies how interrupts can be shared between devices attached to the PCI bus. In most cases, the small amount of latency added by interrupt sharing does not affect the operation or throughput of the devices. In some special cases where maximum performance is needed from a device, a PCI device should not share an interrupt with other PCI devices. Use the following information to avoid sharing an interrupt with a PCI add-in card. PCI devices are categorized as follows to specify their interrupt grouping: • INTA: By default, all add-in cards that require only one interrupt are in this category. For almost all cards that require more than one interrupt, the first interrupt on the card is also classified as INTA. • INTB: Generally, the second interrupt on add-in cards that require two or more interrupts is classified as INTB. (This is not an absolute requirement.) • INTC and INTD: Generally, a third interrupt on add-in cards is classified as INTC and a fourth interrupt is classified as INTD. The ICH5 has eight Programmable Interrupt Request (PIRQ) input signals. All PCI interrupt sources either onboard or from a PCI add-in card connect to one of these PIRQ signals. Some PCI interrupt sources are electrically tied together on the Desktop Board D865GVHZ and therefore share the same interrupt. Table 24 shows an example of how the PIRQ signals are routed. For example, using Table 24 as a reference, assume an add-in card using INTA is plugged into PCI bus connector 3. In PCI bus connector 3, INTA is connected to PIRQB, which is already connected to the ICH5 audio controller. The add-in card in PCI bus connector 3 now shares an interrupt with the onboard interrupt source. 58 Technical Reference Table 24. PCI Interrupt Routing Map ICH5 PIRQ Signal Name PCI Interrupt Source PIRQA PIRQB PIRQC PIRQD PIRQE PIRQF PIRQG PIRQH ICH5 USB UHCI controller 1 INTA SMBus controller INTB ICH5 USB UHCI controller 2 INTB AC ’97 ICH5 Audio INTB ICH5 LAN INTA ICH5 USB UHCI controller 3 INTC ICH5 USB UHCI controller 4 INTA ICH5 USB 2.0 EHCI controller INTD PCI bus connector 1 INTD INTA INTB INTC PCI bus connector 2 INTC INTB INTA INTD PCI bus connector 3 INTD INTA INTB INTC Serial ATA INTA NOTE ✏ In PIC mode, the ICH5 can connect each PIRQ line internally to one of the IRQ signals (3, 4, 5, 6, 7, 9, 10, 11, 12, 14, and 15). Typically, a device that does not share a PIRQ line will have a unique interrupt. However, in certain interrupt-constrained situations, it is possible for two or more of the PIRQ lines to be connected to the same IRQ signal. Refer to Table 23 for the allocation of PIRQ lines to IRQ signals in APIC mode. 59 Intel Desktop Board D865GVHZ Technical Product Specification 2.8 Connectors CAUTION Only the following connectors have overcurrent protection: Back panel and front panel USB, PS/2, and VGA. The other internal connectors are not overcurrent protected and should connect only to devices inside the computer’s chassis, such as fans and internal peripherals. Do not use these connectors to power devices external to the computer’s chassis. A fault in the load presented by the external devices could cause damage to the computer, the power cable, and the external devices themselves. This section describes the board’s connectors. The connectors can be divided into these groups: • Back panel I/O connectors (see page 61)  PS/2 keyboard and mouse  USB (four ports)  Parallel port  Serial port A  VGA port  LAN  Audio (line out, line in, and mic in) • Internal I/O connectors (see page 62)  Audio (auxiliary line input, ATAPI CD-ROM, and front panel audio)  Fans [three]  Power  Add-in boards (PCI)  Parallel ATA IDE  Diskette drive  SCSI hard drive activity LED (optional)  Chassis intrusion  Serial ATA • External I/O connectors (see page 70)  Front panel USB (two connector for four ports)  Auxiliary front panel power/sleep/message-waiting LED  Front panel (power/sleep/message-waiting LED, power switch, hard drive activity LED, reset switch, and auxiliary front panel power LED) NOTE ✏ When installing the D865GVHZ board in a microATX chassis, make sure that peripheral devices are installed at least 1.5 inches above the main power connector, the diskette drive connector, the Parallel ATA IDE connectors, and the DIMM sockets. 60 Technical Reference 2.8.1 Back Panel Connectors Figure 14 shows the location of the back panel connectors.

Poor audio quality occurs if passive (non-amplified) speakers are connected to this output. 2.8.2 Internal I/O Connectors The internal I/O connectors are divided into the following functional groups: • Audio (see page 63)  Auxiliary line in  ATAPI CD-ROM  Front panel audio • Power and hardware control (see page 65)  Fans [3]  ATX12V power  Main power  Chassis intrusion • Add-in boards and peripheral interfaces (see page 68)  PCI bus  Parallel ATA IDE  Diskette drive  SCSI hard drive activity LED (optional)  Serial ATA 2.8.2.1 Expansion Slots The board has three PCI rev 2.2 compliant local bus slots. The SMBus is routed to PCI bus connector 2 only (ATX expansion slot 6). PCI add-in cards with SMBus support can access sensor data and other information residing on the Desktop Board. NOTE ✏ The SMBus routing to the PCI bus connectors does not conform to the PCI Engineering Change Notice (ECN) “Addition of the SMBus to the PCI Connector ECN”, dated October 5th, 2000. The ECN specifies that SMBus signals must be routed to all PCI bus connectors. On this board, SMBus signals are routed to PCI bus connector 2 only. Add-in cards that implement PCI bus connector pins A40 and A41 for any purpose other than SMBCLK (SMBus clock) and SMBDAT (SMBus data) should not be installed in PCI bus connector 2. For information about Refer to Addition of the SMBus to the PCI Connector ECN http://www.pcisig.com/data/specifications/smb_ecn_04 0501.pdf NOTE ✏ This document references back-panel slot numbering with respect to processor location on the board. PCI slots are identified as PCI slot #x, starting with the slot closest to the processor. Figure 17 (page 68) illustrates the board’s PCI slot numbering. 62 Technical Reference 2.8.2.2 Audio Connectors Figure 15 shows the location of the audio connectors. 12 A 910 B 4 1 C 4 1 D 3 1 OM16408 Item Description For more information see: A Front panel audio Table 25 B ATAPI CD-ROM Table 26 C Auxiliary line in, ATAPI style Table 27 D S/PDIF (optional) Table 28 Figure 15.

This data is based on a DC analysis of all active components within the board that impact its power delivery subsystems. The analysis does not include PCI add-in cards. Minimum values assume a light load placed on the board that is similar to an environment with no applications running and no USB current draw. Maximum values assume a load placed on the board that is similar to a heavy gaming environment with a 500 mA current draw per USB port. These calculations are not based on specific processor values or memory configurations but are based on the minimum and maximum current draw possible from the board’s power delivery subsystems to the processor, memory, and USB ports. Use the datasheets for add-in cards, such as PCI, to determine the overall system power requirements. The selection of a power supply at the system level is dependent on the system’s usage model and not necessarily tied to a particular processor speed. Table 43. DC Loading Characteristics DC Current at: Mode DC Power +3.3 V +5 V +12 V -12 V +5 VSB Minimum loading 190.00 W 5.00 A 11.00 A 9.00 A 0.03 A 0.60 A Maximum loading 286.00 W 11.00 A 15.00 A 13.00 A 0.10 A 1.40 A 2.11.2 Add-in Board Considerations The Desktop Board D865GVHZ is designed to provide 2 A (average) of +5 V current for each add-in board. The total +5 V current draw for add-in boards for a fully loaded Desktop Board D865GVHZ (all three expansion slots filled) must not exceed 6 A. 2.11.3 Fan Connector Current Capability CAUTION The processor fan must be connected to the processor fan connector, not to a chassis fan connector. Connecting the processor fan to a chassis fan connector may result in onboard component damage that will halt fan operation. Table 44 lists the current capability of the fan connectors. Table 44. Fan Connector Current Capability Fan Connector Maximum Available Current Processor fan 1.0 A Front chassis fan 0.6 A Rear chassis fan 0.6 A 78 Technical Reference 2.11.4 Power Supply Considerations CAUTION The +5 V standby line for the power supply must be capable of providing adequate +5 V standby current. Failure to do so can damage the power supply. The total amount of standby current required depends on the wake devices supported and manufacturing options. System integrators should refer to the power usage values listed in Table 43 when selecting a power supply for use with the board. Additional power required will depend on configurations chosen by the integrator. The power supply must comply with the following recommendations found in the indicated sections of the ATX form factor specification. • The potential relation between 3.3 VDC and +5 VDC power rails (Section 4.2) • The current capability of the +5 VSB line (Section 4.2.1.2) • All timing parameters (Section 4.2.1.3) • All voltage tolerances (Section 4.2.2) For information about Refer to Section 1.4, page 17 The ATX form factor specification 2.12 Thermal Considerations CAUTION The use of an Intel Pentium 4 processor operating above 2.80 GHz with this Intel desktop board requires the following: • A chassis with appropriate airflow to ensure proper cooling of the components on the board • A processor fan heatsink that meets the thermal performance targets for Pentium 4 processors operating above 2.80 GHz Failure to ensure appropriate airflow may result in reduced performance of both the processor and/or voltage regulator or, in some instances, damage to the desktop board.

The FWH contains the BIOS Setup program, POST, the PCI auto-configuration utility, and Plug and Play support. The BIOS displays a message during POST identifying the type of BIOS and a revision code. The initial production BIOSs are identified as BF86510A.86A. When the BIOS Setup configuration jumper is set to configure mode and the computer is powered- up, the BIOS compares the CPU version and the microcode version in the BIOS and reports if the two match. For information about Refer to The Desktop Boards’ compliance level with Plug and Play Section 1.4, page 17 3.2 BIOS Flash Memory Organization The Firmware Hub (FWH) includes a 4 Mbit (512 KB) symmetrical flash memory device. 87 Intel Desktop Board D865GVHZ Technical Product Specification 3.3 Resource Configuration 3.3.1 PCI Autoconfiguration The BIOS can automatically configure PCI devices. PCI devices may be onboard or add-in cards. Autoconfiguration lets a user insert or remove PCI cards without having to configure the system. When a user turns on the system after adding a PCI card, the BIOS automatically configures interrupts, the I/O space, and other system resources. Any interrupts set to Available in Setup are considered to be available for use by the add-in card. For information about Refer to The versions of PCI and Plug and Play supported by the BIOS Section 1.4, page 17 3.3.2 PCI IDE Support If you select Auto in the BIOS Setup program, the BIOS automatically sets up the two PCI IDE connectors with independent I/O channel support. The IDE interface supports hard drives up to ATA-66/100 and recognizes any ATAPI compliant devices, including CD-ROM drives, tape drives, and Ultra DMA drives (see Section 1.4 for the supported version of ATAPI). The BIOS determines the capabilities of each drive and configures them to optimize capacity and performance. To take advantage of the high capacities typically available today, hard drives are automatically configured for Logical Block Addressing (LBA) and to PIO Mode 3 or 4, depending on the capability of the drive. You can override the auto-configuration options by specifying manual configuration in the BIOS Setup program. To use ATA-66/100 features the following items are required: • An ATA-66/100 peripheral device • An ATA-66/100 compatible cable • ATA-66/100 operating system device drivers NOTE ✏ Do not connect an ATA device as a slave on the same IDE cable as an ATAPI master device. For example, do not connect an ATA hard drive as a slave to an ATAPI CD-ROM drive. 88 Overview of BIOS Features 3.4 System Management BIOS (SMBIOS) SMBIOS is a Desktop Management Interface (DMI) compliant method for managing computers in a managed network. The main component of SMBIOS is the Management Information Format (MIF) database, which contains information about the computing system and its components. Using SMBIOS, a system administrator can obtain the system types, capabilities, operational status, and installation dates for system components. The MIF database defines the data and provides the method for accessing this information. The BIOS enables applications such as third-party management software to use SMBIOS. The BIOS stores and reports the following SMBIOS information: • BIOS data, such as the BIOS revision level • Fixed-system data, such as peripherals, serial numbers, and asset tags • Resource data, such as memory size, cache size, and processor speed • Dynamic data, such as event detection and error logging Non-Plug and Play operating systems, such as Windows NT*, require an additional interface for obtaining the SMBIOS information. The BIOS supports an SMBIOS table interface for such operating systems. Using this support, an SMBIOS service-level application running on a non-Plug and Play operating system can obtain the SMBIOS information. For information about Refer to The Desktop Boards’ compliance level with SMBIOS Section 1.4, page 17 3.5 Legacy USB Support Legacy USB support enables USB devices such as keyboards, mice, and hubs to be used even when the operating system’s USB drivers are not yet available. Legacy USB support is used to access the BIOS Setup program, and to install an operating system that supports USB. By default, Legacy USB support is set to Enabled. Legacy USB support operates as follows: 1. When you apply power to the computer, legacy support is disabled. 2. POST begins. 3. Legacy USB support is enabled by the BIOS allowing you to use a USB keyboard to enter and configure the BIOS Setup program and the maintenance menu. 4. POST completes. 5. The operating system loads. While the operating system is loading, USB keyboards and mice are recognized and may be used to configure the operating system. (Keyboards and mice are not recognized during this period if Legacy USB support was set to Disabled in the BIOS Setup program.) 6. After the operating system loads the USB drivers, all legacy and non-legacy USB devices are recognized by the operating system, and Legacy USB support from the BIOS is no longer used. 89 Intel Desktop Board D865GVHZ Technical Product Specification To install an operating system that supports USB, verify that Legacy USB support in the BIOS Setup program is set to Enabled and follow the operating system’s installation instructions. NOTE ✏ Legacy USB support is for keyboards, mice, and hubs only. Other USB devices are not supported in legacy mode. 3.6 BIOS Updates The BIOS can be updated using either of the following utilities, which are available on the Intel World Wide Web site: ® • Intel Express BIOS Update utility, which enables automated updating while in the Windows environment. Using this utility, the BIOS can be updated from a file on a hard disk, a 1.44 MB diskette, or a CD-ROM, or from the file location on the Web. ® • Intel Flash Memory Update Utility, which requires creation of a boot diskette and manual rebooting of the system. Using this utility, the BIOS can be updated from a file on a 1.44 MB diskette (from a legacy diskette drive or an LS-120 diskette drive) or a CD-ROM. Both utilities support the following BIOS maintenance functions: • Verifying that the updated BIOS matches the target system to prevent accidentally installing an incompatible BIOS. • Updating both the BIOS boot block and the main BIOS. This process is fault tolerant to prevent boot block corruption. • Updating the BIOS boot block separately. • Changing the language section of the BIOS. • Updating replaceable BIOS modules, such as the video BIOS module. • Inserting a custom splash screen. NOTE ✏ Review the instructions distributed with the upgrade utility before attempting a BIOS update. For information about Refer to The Intel World Wide Web site Section 1.2, page 16 3.6.1 Language Support The BIOS Setup program and help messages are supported in five languages: US English, German, Italian, French, and Spanish. The default language is US English, which is present unless another language is selected in the BIOS Setup program. 90 Overview of BIOS Features 3.6.2 Custom Splash Screen ® During POST, an Intel splash screen is displayed by default. This splash screen can be augmented with a custom splash screen. A utility is available from Intel to assist with creating a custom splash screen. The custom splash screen can be programmed into the flash memory using the BIOS upgrade utility. Information about this capability is available on the Intel Support World Wide Web site. NOTE ✏ If you add a custom splash screen, it will share space with the Intel branded logo. For information about Refer to The Intel World Wide Web site Section 1.2, page 16 3.7 Recovering BIOS Data Some types of failure can destroy the BIOS. For example, the data can be lost if a power outage occurs while the BIOS is being updated in flash memory. The BIOS can be recovered from a diskette using the BIOS recovery mode. When recovering the BIOS, be aware of the following: • Because of the small amount of code available in the non-erasable boot block area, there is no video support. You can only monitor this procedure by listening to the speaker or looking at the diskette drive LED. • The recovery process may take several minutes; larger BIOS flash memory devices require more time. • Two beeps and the end of activity in the diskette drive indicate successful BIOS recovery. • A series of continuous beeps indicates a failed BIOS recovery. To create a BIOS recovery diskette, a bootable diskette must be created and the BIOS update files copied to it. BIOS upgrades and the Intel Flash Memory Update Utility are available from Intel Customer Support through the Intel World Wide Web site. NOTE ✏ Even if the computer is configured to boot from an LS-120 diskette (in the Setup program’s Removable Devices submenu), the BIOS recovery diskette must be a standard 1.44 MB diskette not a 120 MB diskette. For information about Refer to The BIOS recovery mode jumper settings Section 2.9.2, page 75 The Boot menu in the BIOS Setup program Section 4.7, page 119 Contacting Intel customer support Section 1.2, page 16 91 Intel Desktop Board D865GVHZ Technical Product Specification 3.8 Boot Options In the BIOS Setup program, the user can choose to boot from a diskette drive, hard drives, CD-ROM, or the network. The default setting is for the diskette drive to be the first boot device, the hard drive second, and the ATAPI CD-ROM third. The fourth device is disabled. 3.8.1 CD-ROM Boot Booting from CD-ROM is supported in compliance to the El Torito bootable CD-ROM format specification. Under the Boot menu in the BIOS Setup program, ATAPI CD-ROM is listed as a boot device. Boot devices are defined in priority order. Accordingly, if there is not a bootable CD in the CD-ROM drive, the system will attempt to boot from the next defined drive. For information about Refer to The El Torito specification Section 1.4, page 17 3.8.2 Network Boot The network can be selected as a boot device. This selection allows booting from the onboard LAN or a network add-in card with a remote boot ROM installed. Pressing the key during POST automatically forces booting from the LAN. To use this key during POST, the User Access Level in the BIOS Setup program’s Security menu must be set to Full. For information about Refer to The BIOS Setup program’s Security menu Table 71, page 117 3.8.3 Booting Without Attached Devices For use in embedded applications, the BIOS has been designed so that after passing the POST, the operating system loader is invoked even if the following devices are not present: • Video adapter • Keyboard • Mouse 3.8.4 Changing the Default Boot Device During POST Pressing the key during POST causes a boot device menu to be displayed. This menu displays the list of available boot devices (as set in the BIOS setup program’s Boot Device Priority Submenu). Table 50 lists the boot device menu options. Table 50. Boot Device Menu Options Boot Device Menu Function Keys Description <↑> or <↓> Selects a default boot device Exits the menu, saves changes, and boots from the selected device Exits the menu without saving changes 92 Overview of BIOS Features ® 3.9 Fast Booting Systems with Intel Rapid BIOS Boot These factors affect system boot speed: • Selecting and configuring peripherals properly ® • Using an optimized BIOS, such as the Intel Rapid BIOS 3.9.1 Peripheral Selection and Configuration The following techniques help improve system boot speed: • Choose a hard drive with parameters such as “power-up to data ready” less than eight seconds, that minimize hard drive startup delays. • Select a CD-ROM drive with a fast initialization rate. This rate can influence POST execution time. • Eliminate unnecessary add-in adapter features, such as logo displays, screen repaints, or mode changes in POST. These features may add time to the boot process. • Try different monitors. Some monitors initialize and communicate with the BIOS more quickly, which enables the system to boot more quickly. 3.9.2 Intel Rapid BIOS Boot Use of the following BIOS Setup program settings reduces the POST execution time. In the Boot Menu: • Set the hard disk drive as the first boot device. As a result, the POST does not first seek a diskette drive, which saves about one second from the POST execution time. • Disable Quiet Boot, which eliminates display of the logo splash screen. This could save several seconds of painting complex graphic images and changing video modes. • Enable Intel Rapid BIOS Boot. This feature bypasses memory count and the search for a diskette drive. In the Peripheral Configuration submenu, disable the LAN device if it will not be used. This can reduce up to four seconds of option ROM boot time. NOTE ✏ It is possible to optimize the boot process to the point where the system boots so quickly that the Intel logo screen (or a custom logo splash screen) will not be seen. Monitors and hard disk drives with minimum initialization times can also contribute to a boot time that might be so fast that necessary logo screens and POST messages cannot be seen. This boot time may be so fast that some drives might be not be initialized at all. If this condition should occur, it is possible to introduce a programmable delay ranging from three to 30 seconds (using the Hard Disk Pre-Delay feature of the Advanced Menu in the Drive Configuration Submenu of the BIOS Setup program). For information about Refer to Drive Configuration Submenu in the BIOS Setup program Section 4.4.4, page 104 93 Intel Desktop Board D865GVHZ Technical Product Specification 3.10 BIOS Security Features The BIOS includes security features that restrict access to the BIOS Setup program and who can boot the computer. A supervisor password and a user password can be set for the BIOS Setup program and for booting the computer, with the following restrictions: • The supervisor password gives unrestricted access to view and change all the Setup options in the BIOS Setup program. This is the supervisor mode. • The user password gives restricted access to view and change Setup options in the BIOS Setup program. This is the user mode. • If only the supervisor password is set, pressing the key at the password prompt of the BIOS Setup program allows the user restricted access to Setup. • If both the supervisor and user passwords are set, users can enter either the supervisor password or the user password to access Setup. Users have access to Setup respective to which password is entered. • Setting the user password restricts who can boot the computer. The password prompt will be displayed before the computer is booted. If only the supervisor password is set, the computer boots without asking for a password. If both passwords are set, the user can enter either password to boot the computer. Table 51 shows the effects of setting the supervisor password and user password. This table is for reference only and is not displayed on the screen. Table 51.

If the POST fails, execution stops and the last POST code generated is left at port 80h. This code is useful for determining the point where an error occurred. Displaying the POST-codes requires a PCI bus add-in card, often called a POST card. The POST card can decode the port and display the contents on a medium such as a seven-segment display. NOTE ✏ The POST card must be installed in PCI bus connector 1. The tables below offer descriptions of the POST codes generated by the BIOS. Table 81 defines the uncompressed INIT code checkpoints, Table 82 describes the boot block recovery code checkpoints, and Table 83 lists the runtime code uncompressed in F000 shadow RAM. Some codes are repeated in the tables because that code applies to more than one operation. Table 81. Uncompressed INIT Code Checkpoints Code Description of POST Operation D0 NMI is Disabled. Onboard KBC, RTC enabled (if present). Init code Checksum verification starting. D1 Keyboard controller BAT test, CPU ID saved, and going to 4 GB flat mode.

Table 84 describes the bus initialization checkpoints. Table 84. Bus Initialization Checkpoints Checkpoint Description 2A Different buses init (system, static, and output devices) to start if present. 38 Different buses init (input, IPL, and general devices) to start if present. 39 Display different buses initialization error messages. 95 Init of different buses optional ROMs from C800 to start. While control is inside the different bus routines, additional checkpoints are output to port 80h as WORD to identify the routines under execution. In these WORD checkpoints, the low byte of the checkpoint is the system BIOS checkpoint from which the control is passed to the different bus routines. The high byte of the checkpoint is the indication of which routine is being executed in the different buses. Table 85 describes the upper nibble of the high byte and indicates the function that is being executed. Table 85. Upper Nibble High Byte Functions Value Description 0 func#0, disable all devices on the bus concerned. 1 func#1, static devices init on the bus concerned. 2 func#2, output device init on the bus concerned. 3 func#3, input device init on the bus concerned. 4 func#4, IPL device init on the bus concerned. 5 func#5, general device init on the bus concerned. 6 func#6, error reporting for the bus concerned. 7 func#7, add-on ROM init for all buses. 129 Intel Desktop Board D865GVHZ Technical Product Specification Table 86 describes the lower nibble of the high byte and indicates the bus on which the routines are being executed. Table 86.

The speaker provides audible error code (beep code) information during POST. For information about Refer to The location of the onboard speaker on the Desktop Board D865GVHZ Figure 1, on page 14 5.5 BIOS Beep Codes Whenever a recoverable error occurs during POST, the BIOS displays an error message describing the problem (see Table 87). The BIOS also issues a beep code (one long tone followed by two short tones) during POST if the video configuration fails (a faulty video card or no card installed) or if an external ROM module does not properly checksum to zero. An external ROM module (for example, a video BIOS) can also issue audible errors, usually consisting of one long tone followed by a series of short tones. For more information on the beep codes issued, check the documentation for that external device. There are several POST routines that issue a POST terminal error and shut down the system if they fail. Before shutting down the system, the terminal-error handler issues a beep code signifying the test point error, writes the error to I/O port 80h, attempts to initialize the video and writes the error in the upper left corner of the screen (using both monochrome and color adapters). 130 Error Messages and Beep Codes If POST completes normally, the BIOS issues one short beep before passing control to the operating system.
