Functional Architecture This chapter provides a high-level description of the functionality distributed between the architectural blocks of the Intel Server Board S875WP1-E. 3.1 Processor and Memory Subsystem The Intel 82875P Memory Controller Hub (MCH) is one component of the Intel 875P chipset. The MCH is a centralized controller for the system bus, the memory bus, the AGP bus, and the accelerated hub architecture interface. 3.1.1 Processor Support The Intel Server Board S875WP1-E supports a single Pentium 4 processor (in a µPGA478 socket) with a system bus of 400 /533 /800 MHz. The server board supports the processors listed in Table 1. Table 1. Processor Support Matrix Type Designation System Bus L2 Cache Size Pentium® 4 processor with 2.40, 2.60, 2.80, and 3.0 GHz 800 MHz 512 KB Hyperthreading (HT) Technology Pentium 4 processor with 3.06 GHz 533 MHz 512 KB Hyperthreading Technology Pentium 4 processor 2.0, 2.26, 2.4, 2.53, 2.6, 2.66, and 2.8 400 / 533 MHz 512 KB GHz CAUTION Use only the processors listed above. Use of unsupported processors can damage the board, the processor, and the power supply. See the Intel® Server Board S875WP1-E Specification Update or go to http://support.intel.com/support/motherboards/server/S875WP1-E/ for the current list of supported processors for this board. NOTE � Use only ATX12V or EPS12V compliant power supplies with the server board S875WP1-E. ATX12V and EPS12V power supplies have an additional power lead that provides required supplemental power for the Intel Pentium 4 processor. The board will not boot if you do not connect the 20-pin (or 24-pin) and 4-pin (or 8-pin) leads of ATX12V or EPS12V power supplies to the corresponding connectors. Do not use a standard ATX power supply. The board will not boot with a standard ATX power supply. Revision 4.0 5 Functional Architecture S875WP1-E TPS 3.1.1.1 Reset Configuration Logic The BIOS determines the processor stepping, cache size, and other processor information through the CPUID instruction. The requirement is for the processor to run at a fixed speed. The processor cannot be programmed to operate at a lower or higher speed. On the S875WP1-E platform, the BIOS is responsible for configuring the processor speed. The BIOS uses CMOS settings to determine which speed to program into the speed setting device. The processor information is read at every system power-on. 3.1.2 Memory Subsystem The server board S875WP1-E provides four DIMM slots and supports a maximum memory capacity of 4 GB. The DIMM organization is x72, which includes eight ECC check bits. ECC from the DIMMs are passed through to the processor’s system bus. Memory scrubbing, single-bit error correction and multiple-bit error detection is supported. Memory can be implemented with either single-sided (one row) or double-sided (two row) DIMMs. Table 2. Supported Memory Configurations DIMM Capacity Configuration DDR SDRAM DDR SDRAM Number of DDR Density Organization SDRAM Devices Front-side/Back-side 64 MB SS 64 Mbit 8 M x 8/empty 8 64 MB SS 128 Mbit 8 M x 16/empty 4 128 MB DS 64 Mbit 8 M x 8/8 M x 8 16 128 MB SS 128 Mbit 16 M x 8/empty 8 128 MB SS 256 Mbit 16 M x 16/empty 4 256 MB DS 128 Mbit 16 M x 8/16 M x 8 16 256 MB SS 256 Mbit 32 M x 8/empty 8 256 MB SS 512 Mbit 32 M x 16/empty 4 512 MB DS 256 Mbit 32 M x 8/32 M x 8 16 512 MB SS 512 Mbit 64 M x 8/empty 8 1024 MB DS 512 Mbit 64 M x 8/64 M x 8 16 Note: In the second column, “DS” refers to double-sided memory modules (containing two rows of DDR SDRAM) and “SS” refers to single-sided memory modules (containing one row of DDR SDRAM). DIMM and memory configurations must adhere to the following: • 2.5 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. • Maximum total system memory: 4 GB • Minimum total system memory: 128 MB • ECC and non-ECC DIMMs supported • Serial Presence Detect • PC3200 (400 MHZ), PC2700 (333 MHZ), and PC2100 (266 MHZ) SDRAM DIMMs 6 Revision 4.0 S875WP1-E TPS Functional Architecture Table 3 lists the supported system bus frequency and memory speed combinations. Table 3. Supported System Bus Frequency and Memory Speed Combinations To use this type of DIMM… The processor's system bus frequency must be… PC3200 (400 MHZ) 800 MHz PC2700 (333 MHZ) 800 or 533 MHz (Note) PC2100 (266 MHZ) 800, 533, or 400 MHz Note: When using PC2700 (333 MHZ) memory with an 800 MHz system bus frequency processor, the memory channel will be set to 320 MHz. Only DIMMs tested and qualified by Intel or a designated memory test vendor will be supported on the Intel Server Board S875WP1-E. A list of qualified DIMMs will be made available through http://support.intel.com/support/motherboards/server/S875WP1-E/ . Note that all DIMMs are supported by design, but only fully qualified DIMMs will be supported. NOTES � • Remove the AGP video card while installing or upgrading memory to avoid interference with the memory retention mechanism. • 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. • For ECC functionality, all installed DIMMs must be ECC. If both ECC and non-ECC DIMMs are used, ECC will be disabled and will not function. • Only low profile DIMMs can be supported in a 1U server chassis. 3.1.3 Memory Configurations The Intel 82875P MCH component provides two features for enhancing memory throughput: • Dual Channel memory interface. The board has two memory channels, each with two DIMM sockets. • Dynamic Addressing Mode. Dynamic mode minimizes overhead by reducing memory accesses. Revision 4.0 7 Functional Architecture S875WP1-E TPS Table 4 summarizes the characteristics of dual and single channel configurations with and without the use of Dynamic Mode. Table 4.

While based on the PCI Local Bus Specification, Rev. 2.2, AGP is independent of the PCI bus and is intended for exclusive use with graphical display devices. AGP overcomes certain limitations of the PCI bus related to handling large amounts of graphics data with the following features: • Pipelined memory read and write operations that hide memory access latency • Demultiplexing of address and data on the bus for nearly 100 percent efficiency NOTES � • AGP 2x operation is not supported. • Install memory in the DIMM sockets prior to installing the AGP video card to avoid interference with the memory retention mechanism. • The AGP connector is keyed for Universal 0.8 V AGP 3.0 cards or 1.5 V AGP 2.0 cards only. Do not attempt to install a legacy 3.3 V AGP card. The AGP connector is not mechanically compatible with legacy 3.3 V AGP cards. For information about Refer to The AGP connector Section 5.3 3.2.2 USB The Intel Server Board S875WP1-E supports up to six USB 2.0 ports, supports Universal Host Controller Interface (UHCI) and Enhanced Host Controller Interface (EHCI), and uses UHCI- and EHCI-compatible drivers. The ICH5-R provides the USB controller for all ports, as shown in Figure 7. The port arrangement is as follows: • Two ports are implemented with stacked back panel connectors, above NIC1 • Two ports are implemented with stacked back panel connectors, above NIC2 • Two ports are routed to the front panel USB header 14 Revision 4.0 S875WP1-E TPS Functional Architecture Back panel USB connectors USB USB ports [2] above NIC1 82801ER Back panel USB connectors USB USB ports [2] I/O Controller Hub above NIC2 (ICH5-R) Front panel USB header USB USB ports [2] Providing up to 2 USB ports OM16101 Figure 7.

The 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. The 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-R ATA- 100 logic can achieve read transfer rates up to 100 MB/sec and write transfer rates up to 88 MB/sec. Revision 4.0 15 Functional Architecture S875WP1-E TPS NOTE � ATA-66 and ATA-100 are faster timings and require a specialized 40-pin, 80-wire cable to reduce reflections, noise, and inductive coupling. The IDE interfaces also support ATAPI devices (such as CD-ROM drives) and ATA devices using the transfer modes. 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 Server Board S875WP1-E supports Laser Servo (LS-120) diskette technology through the IDE interfaces. The BIOS supports booting from an LS-120 drive. � NOTE The BIOS will always recognize an LS-120 drive as an ATAPI floppy drive. To ensure correct operation, do not configure the drive as a hard disk drive.

For proper operation, this connector should be wired to the LED output of the add-in SCSI controller. The LED indicates when data is being read from, or written to, both the add-in SCSI controller and the IDE controller. For information about Refer to The location of the SCSI hard drive activity LED connector Figure 1 16 Revision 4.0 S875WP1-E TPS Functional Architecture 3.2.4 Real-Time Clock, CMOS SRAM, and Battery The real-time clock provides a time-of-day clock and a multi-century calendar with alarm features. The real-time clock supports 256 bytes of battery-backed CMOS SRAM in two banks that are reserved for BIOS use. A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When the computer is not plugged into a wall socket, the battery has an estimated life of three years. When the computer is plugged in, the standby current from the power supply extends the life of the battery. The clock is accurate to ± 13 minutes/year at 25 ºC with 3.3 VSB applied. The time, date, and CMOS values can be specified in the BIOS Setup program. The CMOS values can be returned to their defaults by using the BIOS Setup program. � NOTE If the battery and AC power fail, custom defaults, if previously saved, will be loaded into CMOS RAM at power-on. 3.2.5 Intel 82802AC 8 Megabit Firmware Hub (FWH) The FWH provides the following: • System BIOS program • Logic that enables protection for storing and updating of platform information Revision 4.0 17 Functional Architecture S875WP1-E TPS 3.3 Serial ATA (SATA) Support 3.3.1 SATA Interfaces The Serial ATA controller provided by the ICH5-R offers two independent SATA ports with a theoretical maximum transfer rate of 150MB/s per port. One device can be installed on each port for a maximum of two SATA devices when using ICH5-R. Server board with order code of S875WP1 includes only two SATA ports through the ICH5-R. Server board with order code S875WP1LX includes an additional four SATA ports using an onboard Promise* Serial ATA controller, for a maximum of six SATA drives. A point-to-point interface is used for host to device connections, unlike IDE which supports a master/slave configuration and two devices per channel. For compatibility, the underlying SATA functionality is transparent to the operating system. The SATA 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. Key features include: • Two SATA ports • Maximum throughput of 150MB/s • Smaller cable � NOTE • Many SATA drives use new low-voltage power connectors and require adaptors or power supplies equipped with low-voltage power connectors. For more information, see: http://www.serialata.org/ • ATA and SATA add-in controllers may experience resource conflicts IRQ 14 and 15. Refer to the tested hardware and operating system list at (URL). In some instances, onboard SATA controller may need to be disable to use those add-in controllers. 3.3.2 SATA RAID with ICH5-R Controller Support for RAID (Redundant Array of Independent Disks) on the two SATA ports from the ICH5-R controller is planned for a future date. See http://support.intel.com/support/motherboards/server/S875WP1-E/ for the availability information. 18 Revision 4.0 S875WP1-E TPS Functional Architecture * 3.3.3 SATA RAID with Promise Technology PDC20319 The Intel Server Board S875WP1LX provides additional four port Serial ATA through the use of the Promise* Technology PDC20319 ASIC. The PDC20319 SATA-150 controller contains four independent SATA channels that share a single 32-bit, 33-MHz PCI bus master interface as a multifunction device, packaged in a 144-pin LQFP. The PDC 20319 controller supports the following features: • Burst bus mastering and advanced packet command based scatter/gather engine to enhance overall system performance • Built in 4 channels SATA PHY, which meets the SATA 1.0 specification and can transfer data with 1.5GHz speed • Capable to support multiple arrays and quad master mode for dedicated SATA channel, up to four physical drive can operated at master mode. • Quad independent data paths with read ahead and write posting supported for quad IDE channels to have high performance • PCI interface that complies with PCI Local Bus Specification Revision 2.3 and PCI power management 1.1 • Support 48-bit LBA format for drives larger than 128GB • 32-bit, 33-MHz bus speed and 150 MB/sec sustained transfer rate. The Promise* PDC20319 supports SATA RAID through four SATA Channels. The RAID Engine supports advance chained packet commands for XOR and four independent ATA operations improving performance for all RAID levels. In a RAID configuration, multiple SATA hard drives are placed into one or more arrays of disks. Each array is seen as an independent disk, though the array may include upwards of two, three, or four drives. The SATA RAID can be configured as follows: • RAID 0: Striping one to four drives. • RAID 1: Mirroring two drives. • RAID 10: Striping and mirroring of data concurrently (requires 4 drives) RAID 0 configurations are used for high-performance applications, as it doubles the sustained transfer rate of its drives. RAID 1 configurations are primarily used for data protection. It creates an identical drive backup to a secondary drive. Whenever a disk write is performed, the controller sends data simultaneously to a second drive located on a different data channel. With four drives attached to four SATA channels, one pair of striped drives can mirror themselves to another pair (RAID 10) for storage capacity and data redundancy. Revision 4.0 19 Functional Architecture S875WP1-E TPS 3.4 I/O Controller The SMSC* LPC47M102 I/O Controller provides the following features: • One serial port • One parallel port with Extended Capabilities Port (ECP) and Enhanced Parallel Port (EPP) support • Serial IRQ interface compatible with serialized IRQ support for PCI systems • PS/2-style mouse and keyboard interfaces • Interface for one 1.44 MB diskette drive • Intelligent power management, including a programmable wake-up event interface • PCI power management support The BIOS Setup program provides configuration options for the I/O controller.

For the chassis intrusion circuit to function, the chassis’ power supply must be connected to AC power. The security feature uses a mechanical switch on the chassis that attaches to the chassis intrusion connector. When the chassis cover is removed the mechanical switch is in the closed position. For information about Refer to The location of the chassis intrusion connector Figure 1 � NOTE Chassis intrusion detection may be implemented using LANDesk* Client Manager or other third- party software. 3.6 Power Management Power management is implemented at several levels, including: 10 Software support through Advanced Configuration and Power Interface (ACPI) 11 Hardware support: � Power connector � Fan connectors � LAN wake capabilities � Instantly Available PC technology � Wake from USB � Wake from PS/2 devices � Power Management Event (PME#) wake-up support 3.6.1 Advanced Configuration and Power Interface (ACPI) ACPI gives the operating system direct control over the power management and Plug and Play functions of a computer. The use of ACPI with the Intel Server Board S875WP1-E requires an operating system that provides full ACPI support. ACPI features include: 12 Plug and Play (including bus and device enumeration) 13 Power management control of individual devices, add-in boards (some add-in boards may require an ACPI-aware driver), video displays, and hard disk drives 14 Methods for achieving less than 15-watt system operation in the standby or sleeping state 15 A Soft-off feature that enables the operating system to power-off the computer 16 Support for multiple wake-up events (see Table 7) • Support for a front panel power and sleep mode switch Revision 4.0 23 Functional Architecture S875WP1-E TPS Table 5 lists the system states based on how long the power switch is pressed, depending on how ACPI is configured with an ACPI-aware operating system. Table 5. Effects of Pressing the Power Switch …and the power switch is If the system is in this state… pressed for …the system enters this state Off Less than four seconds Power-on (ACPI S5 – Soft off) (ACPI S0 – working state) On Less than four seconds Soft-off/Standby (ACPI S0 – working state) (ACPI S1 or S3 – sleeping state) On More than four seconds Fail safe power-off (ACPI S0 – working state) (ACPI S5 – Soft off) Sleep Less than four seconds Wake-up (ACPI S1 or S3 – sleeping state) (ACPI S0 – working state) Sleep More than four seconds Power-off (ACPI S1 or S3 – sleeping state) (ACPI S5 – Soft off) 3.6.1.1 System States and Power States Under ACPI, the operating system directs all system and device power state transitions. The operating system puts devices in and out of low-power states based on user preferences and knowledge of how devices are being used by applications. Devices that are not being used can be turned off. The operating system uses information from applications and user settings to put the system as a whole into a low-power state. Table 6 lists the power states supported by the Server Board S875WP1-E along with the associated system power targets. See the ACPI specification for a complete description of the various system and power states. Table 6.

Total system power is dependent on the system configuration, including add-in boards and peripherals powered by the system chassis’ power supply. 2. Dependent on the standby power consumption of wake-up devices used in the system. 3.6.1.2 Wake-up Devices and Events Table 7 lists the devices or specific events that can wake the computer from specific states. Table 7. Wake-up Devices and Events These devices/events can wake up the …from this state computer… LAN S1, S3, S4, S5 (Note) Modem (back panel Serial Port A) S1, S3 PME# S1, S3, S4, S5 (Note) 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#, 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. • 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. 3.6.1.3 Plug and Play In addition to power management, ACPI provides control information so that operating systems can facilitate Plug and Play. ACPI is used only to configure devices that do not use other hardware configuration standards. PCI devices for example, are not configured by ACPI. Revision 4.0 25 Functional Architecture S875WP1-E TPS 3.6.2 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 Server Board S875WP1-E provides power management hardware features, including: 17 Power connector 18 Fan connectors 19 LAN wake capabilities 20 Instantly Available PC technology 21 Wake from USB 22 Wake from PS/2 keyboard • PME# 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. 3.6.2.1 Power Connector ATX12V or EPS12V compliant power supplies and the Intel Server Board S875WP1-E can turn off the system power through software control. When the system receives the correct command from the operating system, the power supply removes non-standby voltages from the system. When power to the computer is interrupted by a power outage or a disconnected power cord, when power resumes, 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 After Power Failure in the BIOS Setup program’s Boot menu. For information about Refer to The location of the power connectors Figure 1 The signal names of the power connector Section 5.1 The BIOS Setup program’s Boot menu Section 7.1.5 26 Revision 4.0 S875WP1-E TPS Functional Architecture 3.6.2.2 Fan Connectors 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 8 summarizes the fan connector function/operation. Table 8. 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. Fan is off when the system is off or in the S3, S4, or S5 state. • Wired to a fan tachometer input of the hardware monitoring and fan control ASIC. • Closed-loop fan control that can adjust the fan speed or switch the fan on or off as needed. System fans • +12 V DC connection for a system or chassis fan. • Fan is on in the S0 or S1 state. Fan is off when the system is off or in the S3, S4, or S5 state. • Wired to a fan tachometer input of the hardware monitoring and fan control ASIC. • Closed-loop fan control that can adjust the fan speed or switch the fan on or off as needed. For information about: Refer to: The location of the fan connectors Figure 1 The signal names of the fan connectors Section 5.13.1 3.6.2.3 LAN Wake Capabilities CAUTION For LAN wake capabilities, the +5 V standby from the power supply must be capable of providing adequate +5 V standby current. 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 server board S875WP1-E supports LAN wake capabilities with ACPI in the following ways: 23 PCI bus PME# signal for PCI 2.2 compliant LAN designs • Onboard LAN subsystem Revision 4.0 27 Functional Architecture S875WP1-E TPS 3.6.2.4 Instantly Available PC Technology CAUTION For Instantly Available* PC technology, the +5 V standby from 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 server board S875WP1-E to enter the ACPI S3 (Suspend-to-RAM) sleep-state. While in the S3 sleep-state, the server 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 7 lists the devices and events that can wake the computer from the S3 state. The server board supports the PCI Bus Power Management Interface Specification. 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. 3.6.3 Standby Power (+5 V) Indicator LED The standby power indicator LED (CR7J1) shows that power is still present even when the computer appears to be off. Figure 8 shows the location of the standby power indicator LED. CAUTION If AC power has been switched off and the standby power indicator is still lit, disconnect the power cord before installing or removing any devices connected to the board. Failure to do so could damage the board and any attached devices. 28 Revision 4.0 S875WP1-E TPS Functional Architecture CR7J1 TP00185 Figure 8.

Default, but can be changed to another IRQ. 38 Revision 4.0 S875WP1-E TPS Maps and Interrupts 4.6 PCI Interrupt Routing Map This section describes interrupt sharing and how the interrupt signals are connected between the PCI bus connectors and onboard PCI devices. 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: 56 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. 57 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-R 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 Server Board S875WP1-E and therefore share the same interrupt. Table 19 shows an example of how the PIRQ signals are routed. For example, using Table 19 as a reference, assume an add-in card using INTB is plugged into PCI bus connector 3. In PCI bus connector 3, INTB is connected to PIRQA, which is already connected to the Promise PDC20319 Controller. The add-in card in PCI bus connector 3 now shares an interrupt with the onboard interrupt source. Table 19. PCI Interrupt Routing Map PCI Interrupt Source ICH5-R PIRQ Signal Name PIRQA PIRQB PIRQC PIRQD PIRQE PIRQF PIRQG PIRQH AGP connector INTA INTB PCI bus connector 1 INTF INTG INTH INTE PCI bus connector 2 INTG INTF INTE INTH PCI bus connector 3 INTB INTC INTD INTA LAN_10/100 INTE ATI Rage XL INTE Promise PD20319 Controller INTB NOTE � In PIC mode, the ICH5-R 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. See Table 18 for the allocation of PIRQ lines to IRQ signals in APIC mode. Revision 4.0 39 Connectors and Jumper Blocks S875WP1-E TPS 5.

BIOS Features The Intel Server Board S875WP1-E uses an Intel/AMI* BIOS that is stored in the Firmware Hub (FWH) and can be updated using a disk-based program. The FWH contains the BIOS Setup program, POST, the PCI auto-configuration utility, and Plug and Play support. The Intel Server Board S875WP1-E supports system BIOS shadowing, allowing the BIOS to execute from 64-bit on-board write-protected system memory. The BIOS displays a message during POST identifying the type of BIOS and a revision code. The initial production BIOS is identified as WP87510A.86B. When the Intel Server Board S875WP1-E’s jumper is set to configuration mode and the server is powered-up, the BIOS compares the processor version and the microcode version in the BIOS and reports if the two match. For information about Refer to The Intel Server Board S875WP1-E’s compliance level with Plug and Play Section 3.6.1.3 6.1 BIOS Flash Memory Organization The Intel 82802AC Firmware Hub (FWH) includes an 8 megabit symmetrical flash memory device. Internally, the device is grouped into eight 64-KB blocks that are individually erasable, lockable, and unlockable. 6.2 Resource Configuration 6.2.1 PCI Autoconfiguration The BIOS can automatically configure PCI devices. PCI devices may be on-board 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. Autoconfiguration information is stored in ESCD format. Revision 4.0 51 BIOS Features S875WP1-E TPS 6.2.2 PCI IDE Support If Auto is selected from 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 3.2.3). 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. The user 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: 58 An ATA-66/100 peripheral device 59 An ATA-66/100 compatible cable • ATA-66/100 operating system device drivers NOTES � • ATA-66/100 compatible cables are backward compatible with drives using slower IDE transfer protocols. If an ATA-66/100 disk drive and a disk drive using any other IDE transfer protocol are attached to the same cable, the maximum transfer rate between the drives is reduced to that of the slowest device. • 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. 6.3 System Management BIOS (SMBIOS) SMBIOS is a Server 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: 60 BIOS data, such as the BIOS revision level 61 Fixed-system data, such as peripherals, serial numbers, and asset tags 62 Resource data, such as memory size, cache size, and processor speed • Dynamic data, such as event detection and error logging 52 Revision 4.0 S875WP1-E TPS BIOS Features 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. 6.4 Legacy USB Support Legacy USB support enables USB devices such as keyboard, 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 the user applies power to the computer, legacy support is disabled. 2. POST begins. 3. Legacy USB support is enabled by the BIOS allowing the user 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 keyboard and mice are recognized and may be used to configure the operating system. (Keyboard 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. 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 keyboard, mice, and hubs only. Other USB devices are not supported in legacy mode. Revision 4.0 53 BIOS Features S875WP1-E TPS 6.5 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, 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: 63 Verifying that the updated BIOS matches the target system to prevent accidentally installing an incompatible BIOS. 64 Updating both the BIOS boot block and the main BIOS. This process is fault tolerant to prevent boot block corruption. 65 Updating the BIOS boot block separately. 66 Changing the language section of the BIOS. 67 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. 6.5.1 Language Support The BIOS Setup program and help messages are supported in two languages: US English and Spanish. Additional languages may be flashed in if desired (German, Italian and French available). The default language is US English, which is present unless another language is selected in the BIOS Setup program. 6.5.2 Custom Splash Screen During POST, an Intel splash screen is displayed by default. This splash screen can be replaced 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. 54 Revision 4.0 S875WP1-E TPS BIOS Features 6.6 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. The user 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 5.14 The Boot Device Priority menu in the BIOS Setup program Section 7.1.6.1 6.7 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, the ATAPI CD-ROM third, and the network fourth. The fifth device is disabled. 6.7.1 CD-ROM and Network 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. The network can be selected as a boot device. This selection allows booting from the on-board NIC or a network add-in card with a remote boot ROM installed. Revision 4.0 55 BIOS Features S875WP1-E TPS 6.7.2 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: 68 Video adapter 69 Keyboard • Mouse 56 Revision 4.0 S875WP1-E TPS BIOS Features ® 6.8 Fast Booting Systems with Intel Rapid BIOS Boot These factors affect system boot speed: 70 Selecting and configuring peripherals properly • Using an optimized BIOS, such as the Intel Rapid BIOS 6.8.1 Intel Rapid BIOS Boot Using 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. • Enabled Intel Rapid BIOS Boot. This feature bypasses memory count and the search for a diskette drive. NOTES � • 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 7.1.3.4 6.9 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. Revision 4.0 57 BIOS Features S875WP1-E TPS • 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 39 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 39.

Revision 4.0 85 Error Reporting and Handling S875WP1-E TPS 8. Error Reporting and Handling This section documents the types of system bus error conditions monitored by the Intel Server Board S875WP1-E. 8.1 Error Sources and Types One of the major requirements of server management is to correctly and consistently handle system errors. System errors, which can be disabled and enabled individually or as a group, can be categorized as follows: 71 PCI bus 72 Memory single- and multi-bit errors 73 Sensors 74 Processor internal errors, bus/address errors, thermal trip errors, temperatures and voltages, and GTL voltage levels • Errors detected during POST, logged as ‘POST errors’ On the S875WP1-E platform, the Heceta chip manages general hardware monitoring sensors on a hardware level; however action is only taken by software (i.e., an application such as LANDesk™ Client Manager). 8.1.1 PCI Bus Errors The PCI bus defines two error pins, PERR# and SERR#, for reporting PCI parity errors and system errors, respectively. In the case of PERR#, the PCI bus master has the option to retry the offending transaction, or to report it using SERR#. All other PCI-related errors are reported by SERR#. SERR# is routed to NMI if enabled by BIOS. 8.1.2 Processor Bus Errors The MCH supports the data integrity features supported by the Pentium® Pro bus, including address, request, and response parity. The 875P chipset always generates ECC data while it is driving the processor data bus, although the data bus ECC can be disabled or enabled by BIOS. It is enabled by default. 86 Revision 4.0 S875WP1-E TPS Error Reporting and Handling 8.1.3 Single-Bit ECC Error Throttling Prevention The system detects, corrects, and logs correctable errors as long as these errors occur infrequently, the system should continue to operate without a problem. Occasionally, correctable errors are caused by a persistent failure of a single component. Although these errors are correctable, continual calls to the error logger can throttle the system, preventing further useful work. For this reason, the system counts certain types of correctable errors and disables reporting if errors occur too frequently. Error correction remains enabled, but calls to the error handler are disabled. This allows the system to continue running, despite a persistent correctable failure. The BIOS adds an entry to the event log to indicate that logging for that type of error has been disabled. This entry indicates a serious hardware problem that must be repaired at the earliest possible time. The system BIOS implements this feature for correctable bus errors. If ten errors occur within 30 minutes, the corresponding error handler disables further reporting of that type of error. The BIOS re-enables logging and SMIs the next time the system is rebooted. 8.1.4 Memory Bus Errors The MCH is programmed to flag and log single-bit errors (SBEs) and multi-bit errors (MBEs). The MCH then triggers an SMI to the ICH5-R and the ICH5-R asserts the SMI# signal. BIOS then logs the errors in the event log. 8.2 BIOS Error Messages, POST Codes, and BIOS Beep Codes The BIOS indicates the current testing phase during POST by writing a hex code to I/O location 80h. If errors are encountered, error messages or codes will either be displayed to the video screen, or if an error has occurred prior to video initialization, errors will be reported through a series of audio beep codes. POST errors are logged in to the SEL. The error codes are defined by Intel and, whenever possible, are backward compatible with error codes used on earlier platforms. Revision 4.0 87 Error Reporting and Handling S875WP1-E TPS 8.2.1 BIOS Error Messages During POST, if an error is detected, the BIOS will display an error code and message to the screen. The following table defines POST error codes and their associated messages. The BIOS prompts the user to press a key in case of serious errors. Some of the error messages are preceded by the string "Error” to highlight the fact that the system may be malfunctioning. All Comment [JK1]: • •If a BIOS vendor specific error code POST errors and warnings are logged in the SEL. is encountered, how is anyone going to know what it means if they are not defined in this doc?

CMOS memory may have been corrupted. Run Setup to reset values. CMOS Settings Wrong CMOS values are not the same as the last boot. These values have either been corrupted or the battery has failed. CMOS Date/Time Not Set The time and/or date values stored in CMOS are invalid. Run Setup to set correct values. DMA Error Error during read/write test of DMA controller. FDC Failure Error occurred trying to access diskette drive controller. HDC Failure Error occurred trying to access hard disk controller. Checking NVRAM..... NVRAM is being checked to see if it is valid. Update OK! NVRAM was invalid and has been updated. Updated Failed NVRAM was invalid but was unable to be updated. Keyboard Error Error in the keyboard connection. Make sure keyboard is connected properly. KB/Interface Error Keyboard interface test failed. Memory Size Decreased Memory size has decreased since the last boot. If no memory was removed then memory may be bad. Memory Size Increased Memory size has increased since the last boot. If no memory was added there may be a problem with the system. Memory Size Changed Memory size has changed since the last boot. If no memory was added or removed then memory may be bad. No Boot Device Available System did not find a device to boot. 88 Revision 4.0 S875WP1-E TPS Error Reporting and Handling Error Message Explanation Off Board Parity Error A parity error occurred on an off-board card. This error is followed by an address. On Board Parity Error A parity error occurred in on-board memory. This error is followed by an address. Parity Error A parity error occurred in on-board memory at an unknown address. NVRAM/CMOS/PASSWORD cleared by NVRAM, CMOS, and passwords have been cleared. The system Jumper should be powered down and the jumper removed. Pressed CMOS is ignored and NVRAM is cleared. User must enter Setup. 8.2.2 Port 80h POST Codes During the POST, the BIOS generates diagnostic progress codes (POST codes) to I/O port 80h. 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. The tables below offer descriptions of the POST codes generated by the BIOS. Table 68 defines the uncompressed INIT code checkpoints, Table 69 describes the boot block recovery code checkpoints, and Table 70 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 68. Uncompressed INIT Code Checkpoints Code Description of POST Operation D0 NMI is Disabled.

The BIOS also issues a beep code (one long tone 92 Revision 4.0 S875WP1-E TPS Error Reporting and Handling 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). If POST completes normally, the BIOS issues one short beep before passing control to the operating system. Table 71. BIOS Beep Codes Beep Description 1 Refresh failure 2 Parity cannot be reset 3 First 64 KB memory failure 4 Timer not operational 5 Not used 6 8042 GateA20 cannot be toggled 7 Exception interrupt error 8 Display memory R/W error 9 Not used 10 CMOS Shutdown register test error 11 Invalid BIOS (e.g. POST module not found, etc.) Revision 4.0 93 Error Reporting and Handling S875WP1-E TPS 8.3 Bus Initialization Checkpoints The system BIOS gives control to the different buses at several checkpoints to do various tasks. Table 72 describes the bus initialization checkpoints. Table 72. 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 73 describes the upper nibble of the high byte and indicates the function that is being executed. Table 73. 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. Table 74 describes the lower nibble of the high byte and indicates the bus on which the routines are being executed. Table 74.
