Check the Intel Customer Support website for the latest tested memory list:

http://support.intel.com/support/motherboards/server/S875WP1-E

Intel 875P Chipset

The Intel 875P chipset consists of the following devices:

Intel 82875P Memory Controller Hub (MCH) with Accelerated Hub Architecture (AHA) bus

Intel 82801EB I/O Controller Hub (ICH5) with AHA bus

Intel 82802AC Firmware Hub (FWH)

The MCH is a centralized controller for the system bus, the memory bus, the AGP bus, and the Accelerated Hub Architecture interface. The ICH5-R is a centralized controller for the board’s I/O paths. The FWH provides the nonvolatile storage of the BIOS.

Intel 82875P Memory Controller Hub (MCH)

The MCH supports the data integrity features supported by the Pentium 4 processor 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. The MCH controls the Intel 82547EI from the CSA interface.

The MCH provides the following:

An integrated DDR memory controller with auto detection.

Support for ACPI Rev 2.0 compliant power management.

AGP 2.0 slot, also known as AGP 8x

AGP Connector

AGP is a high-performance interface for graphics-intensive applications. AGP is independent of the PCI bus and is intended for exclusive use with graphical display devices. The AGP bus follows the AGP 3.0 specification.

The AGP connector on the server board S875WP1-E supports the following:

2X, 4X, or 8X AGP protocol

1.5 V add-in cards only

Maximum bus bandwidth of 2.13 GB/sec

NOTE

The AGP connector is keyed for 1.5 V AGP 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.

ATA Rage XL Video Controller

The S875WP1-E server board provides an ATI Rage XL PCI graphics accelerator, along with

8 MB of video SDRAM and support circuitry for an embedded SVGA video subsystem. The ATI Rage XL chip contains a SVGA video controller, clock generator, 2D and 3D engine, and RAMDAC in a 272-pin PBGA. One 2Mx32 SDRAM chip provides 8 MB of video memory.

The SVGA subsystem supports a variety of modes, up to 1600 x 1200 resolution in 8/16/24/32 bpp modes under 2D, and up to 1024 x 768 resolution in 8/16/24/32 bpp modes under 3D. It also supports both CRT and LCD monitors up to 100 Hz vertical refresh rate.

The server board S875WP1-E provides a standard 15-pin VGA connector and supports disabling of the on-board video through the BIOS Setup menu or when a plug-in video card is installed in the AGP slot or any of the PCI slots.

Video Modes

The Rage XL chip supports all standard IBM* VGA modes. The following table shows the 2D/3D modes supported for both CRT and LCD. The table specifies the minimum memory requirement for various display resolution, refresh rates, and color depths.

Serial Port

The server board S875WP1-E has one serial port connector and one serial port header. The serial port A connector is located on the back panel. The serial ports’ NS16C550-compatible UART supports data transfers at speeds up to 115.2 kb/s with BIOS support.

A DH10 10-pin serial header is available on the baseboard for an option Serial B port.

Parallel Port

The 25-pin D-Sub parallel port connector is located on the back panel. In the BIOS Setup program, the parallel port can be set to the following modes:

Output only (PC AT*-compatible mode)

Bi-directional (PS/2 compatible)

EPP

ECP

Floppy Drive Controller

The I/O controller supports one diskette drive that is compatible with the 82077 diskette drive controller and supports both PC-AT and PS/2 modes.

Keyboard and Mouse Connectors

PS/2 keyboard and mouse connectors are located on the back panel. The +5 V lines to these connectors are protected with a PolySwitch* circuit that, like a self-healing fuse, reestablishes the connection after an overcurrent condition is removed.

NOTE

The keyboard is supported in the bottom PS/2 connector and the mouse is supported in the top PS/2 connector. Power to the computer should be turned off before a keyboard or mouse is connected or disconnected.

USB

High-Speed USB 2.0 Support

NOTES

Use a shielded cable that meets the requirements for a full-speed USB device. Computer systems that have an unshielded cable attached to a USB port might not meet FCC Class B requirements, even if no device or a lowspeed USB device is attached to the cable.

USB devices are limited to USB 1.1 transfer rates prior to operating system and driver initialization.

The server board supports up to six USB 2.0 ports via the ICH5. Four ports are routed to the back panel. One header, supporting up to two ports, is routed to the front panel. USB 2.0 ports are backward compatible with USB 1.1 devices. USB 1.1 devices will function normally at USB 1.1 speeds.

USB 2.0 support requires both an operating system and drivers that fully support USB 2.0 transfer rates. Disabling High-Speed USB in BIOS reverts all USB 2.0 ports to USB 1.1 operation. This may be required to accommodate operating systems that do not support USB 2.0.

Legacy USB Support

Legacy USB support allows USB devices such as keyboard, mice, and hubs to be used even when the operating system’s USB drivers are not 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.

Four of the USB ports are implemented with stacked back panel connectors; the other two are accessible via the front panel USB header. The S875WP1-E server board fully supports UHCI and uses UHCI-compatible software drivers.

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 s shielded cable that meets the requirements for full-speed devices.

Server Board Features

19

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 is 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.

PCI I/O Subsystem

The primary I/O bus for the server board S875WP1-E is PCI, with one independent PCI bus. The PCI bus complies with the PCI Local Bus Specification, Rev 2.3. The PCI bus is directed through the Intel 82801EB I/O Controller Hub (ICH5-R). The table below lists the characteristics of the PCI bus.

IDE Interfaces

The ICH5-R IDE controller has two independent bus-mastering IDE interfaces that can be independently enabled. The interface handles the exchange of information between the processor and peripheral devices like hard disks and CD-ROM drives. The IDE interfaces supports:

Up to four IDE devices (such as hard drives)

ATAPI devices (such as CD-ROM drives)

Laser servo (LS-120) drives

PIO Mode devices

Ultra DMA-33: DMA protocol on IDE bus supporting host and target throttling and transfer rates of up to 33 MB/sec.

ATA-100/66: DMA protocol on IDE bus supporting host and target throttling and transfer rates of up to 100 MB/sec. The ATA-100/66 protocol is similar to Ultra DMA and is device driver compatible.

NOTE

ATA-100/66 is a faster timing and requires a specialized 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 S875WP1-E server board supports Laser Servo (LS-120) diskette technology through the 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)

SCSI Hard Drive Activity LED Connector

The SCSI hard drive activity LED connector is a 1 x 2-pin connector that allows an add-in SCSI controller to use the same LED as the onboard IDE controller. 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.

Power Management

Power management is implemented at several levels, including:

Software support through Advanced Configuration and Power Interface (ACPI)

Hardware support:

Suspend to RAM (Instantly Available PC technology)

Power connectors

Fan connectors

Resume on Ring

Wake from USB

Wake from PS/2 keyboard/mouse

PME# wakeup support

Software Support through ACPI

The Advance Configuration and Power Interface (ACPI)–aware operating system can place the system into a state where the hard drives spin down, the system fans stop, and all processing is halted. In this state, the power supply is still on and the processors still dissipate some power, so the power supply fan and processor fans are still running.

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.

24

Intel Server Board S875WP1-E Product Guide

ACPI features include:

Plug and Play (including bus and device enumeration)

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

Methods for achieving less than 15-watt system operation in the power-on/standby sleeping state

A soft-off feature that enables the operating system to power-off the computer

Support for multiple wake-up events

Support for a front panel power and sleep mode switch

The Server Board S875WP1-E supports sleep states S0, S1, S2, S3, S4, and S5. When the server board is operating in ACPI mode, the operating system retains control of the system and the operating system policy determines the entry methods and wake-up sources for each sleep state. Sleep entry and wake-up event capabilities are provided by the hardware but are enabled by the operating system. The following is a summary of the supported sleep states:

S0: Normal running state.

S1: Processor sleep state. No context will be lost in this state and the processor caches will maintain coherency.

S3: Suspend to RAM (Instantly Available PC Technology).

S4: Hibernate or Save to Disk. The memory and machine state are saved to disk. Pressing the power button or another wake-up event restores the system state from the disk and resumes normal operation. This state assumes that no hardware changes were made to the system while it was off.

S5: Soft off. Only the RTC section of the chipset is running in this state.

CAUTION

The system is off only when the AC power is disconnected.

Table 8 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.

Wake-up Devices and Events

CAUTION

For LAN wake capabilities, 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 LAN wake capabilities can damage the power supply.

Notes:

1.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.

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.

LAN Wake

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 wakes up the computer from ACPI S1, S3, S4, and S5 state.

Depending on the LAN implementation, the S875WP1-E server board 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

PCI via PME# Wake-up Support

When the PME# signal on the PCI bus is asserted, the computer wakes from an ACPI S1, S3, S4, or S5 state (with Wake on PME enabled in BIOS).

26

Intel Server Board S875WP1-E Product Guide

Resume on Ring

Resume on Ring enables telephony devices to access the computer when it is in a power-managed state. The operation of Resume on Ring wakes the system from the S1 or S3 sleep states when a signal is sent to the serial port at the rear or the chassis or to an internally installed modem. Resume on ring can be summarized as follows:

Resumes operation from ACPI S1 or S3 states

Requires only one call to access the computer

Detects incoming call similarly for external and internal modems

Requires modem interrupt be unmasked for correct operation

Wake from USB

USB bus activity wakes the computer from an ACPI S1 or S3 state.

NOTE

Wake from USB requires the use of a USB peripheral that supports Wake from USB.

Wake from PS/2 Devices

PS/2 device activity, such as moving a PS/2 mouse or pressing a key on a PS/2 keyboard, wakes the computer from an ACPI S1 or S3 state.

Hardware Support

The S875WP1-E server board provides several power management hardware features, including:

Power connector

Fan connectors

Instantly Available PC technology

Instantly Available PC technology and LAN Wake require power from the +5 V standby line. The sections discussing these features describe the incremental standby power requirements.

CAUTION

Ensure that the power supply provides adequate +5 V standby current if Instantly Available PC technology features is 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.

Server Board Features

27

Power Connector

When used with an ATX12V or EPS12V compliant power supply that supports remote power on/off, the S875WP1-E server board can turn off the system power through software control. When the system BIOS receives the correct command from the operating system, the BIOS turns off power to the computer.

With soft-off enabled, if 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 feature in the BIOS Setup program’s Boot menu.

NOTE

A standard ATX 20 pin power connector and standard ATX 12V 4-pin 2x2 connector can be used to power the S875WP1-E board. Plug the power cables into the pin 1 end of their respective motherboard connectors, leaving pins 21-24 unused on the main power connector and 5-8 unused on the 12V connector.

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.

The S875WP1-E server board supports the PCI Bus Power Management Interface Specification. An add-in board that supports 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.

The standby power indicator LED shows that power is still present even when the computer appears to be off. Figure 4 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.
