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

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

Server Board Features

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.

Intel Server Board S875WP1-E Product Guide

Network Interface Controller (NIC)
The server board S875WP1-E supports two Network Interface Controllers (NICs), one that runs at
10/100Mb and is based on the Intel 82562ET NIC and the other that runs at one gigabit and is
based on the Intel 82547EI NIC. When looking at the rear of the chassis, the gigabit NIC is at the
left (closest to the video port) and the 10/100Mb NIC is at the right. You can disable either or both
NICs through BIOS Setup.
The 82562ET is controlled by the ICH5-R and supports the following features:
• Integrated IEEE 802.3 10Base-T and 100Base-TX compatible PHY
• IEEE 802.3u auto-negotiation support
• Full duplex support at both 10 Mbps and 100 Mbps operation
• Low power +3.3 V device with reduced power in unplugged mode and automatic detection of

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.

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.

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.
Table 9 provides an overview of the devices or events that can wake the computer from specific
states.

✏

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).

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

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.

Intel Server Board S875WP1-E Product Guide

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.

The Hardware Management features enable the board to be compatible with the Wired for
Management (WfM) specification. The board has several hardware management features,
including the following:
• Remote temperature sensing near the Vreg
• Power supply monitoring (+5 V, +3.3 V, 3.3 VSB, +1.5 V, and VCCP) to detect levels above
or below acceptable values
• Fan monitoring though four fan tachometer inputs. Monitoring can be implemented using
LANDesk* Client Manager or other third-party software.
• Chassis intrusion detection
The server board S875WP1-E has an integrated Hardware Management ASIC that is responsible
for hardware monitoring. Together, the Hardware Management ASIC and the LANDesk Client
Manager (LDCM) 6.3 software provide basic server hardware monitoring that alerts a system
administrator if a hardware problem occurs on an Intel Server Board S875WP1-E based system.
The LDCM software is for use with Windows 2000 Server and Windows 2000 Advanced Server
operating systems. Other operating systems, such as Red Hat* Linux* are not be monitored with
LDCM.
Intel LANDesk Client Manager software and user guides that provide more information on using
Intel LDCM software are available on the Intel Server Board S875WP1-E Resource CD and are
also available for download at:
http://www.support.intel.com/support/motherboards/server/S875WP1-E

Chassis Intrusion and Detection
The server board S875WP1-E supports a chassis security feature that detects the removal of the
chassis cover. 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. Chassis intrusion options can be configured through the BIOS
Setup screens.

✏

NOTE
Chassis intrusion detection may be implemented using LANDesk Client
Manager or third-party software.

Intel Server Board S875WP1-E Product Guide

Password Security
The BIOS includes security features that restrict whether the BIOS Setup program can be accessed
and who can boot the server. A supervisor password and a user password can be set for the Setup
menu and for booting the server, with the following restrictions:
• The supervisor password gives unrestricted access to view and change all Setup options. If
only the supervisor password is set, pressing at the password prompt of Setup gives the
user restricted access to Setup.
• If both the supervisor and user passwords are set, you must enter either the supervisor password
or the user password to access Setup. Setup options are then available for viewing and
changing depending on whether the supervisor or user password was entered.
• Setting a user password restricts who can boot the server. The password prompt is displayed
before the server is booted. If only the supervisor password is set, the server boots without
asking for a password. If both passwords are set, you can enter either password to boot
the server.

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, will be loaded into CMOS
RAM at power-on if they defaults have been previously saved.

Recovering the CMOS
In the unlikely event that the CMOS should be corrupt, it can be cleared by using a jumper setting
on the server board. To recover the CMOS and return the settings to the default value:
1. Power down the server and unplug all AC power cables.
2. Remove the cover from the chassis.
3. Move the jumper at jumper block J8G1 to cover pins 2 and three. For the location of jumper
block J8G1, see the figure below.

Reconfigure settings as necessary.

BIOS
The S875WP1-E server board 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 S875WP1-E server board supports system BIOS shadowing, allowing the BIOS to execute
from 64-bit onboard 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 S875WP1-E server board’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.

PCI Auto Configuration
The BIOS can automatically configure PCI devices. PCI devices may be onboard or add-in cards.
Auto configuration 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. Auto configuration information is stored in
ESCD format.

IDE Auto Configuration
If you select Auto in the BIOS Setup program, the BIOS automatically sets up the two
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.
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.

Server Board Features

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
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.

BIOS Updates
The BIOS can be updated with the Intel® Flash Memory Update Utility. This utility is available on
the Intel World Wide Web site. The Intel® Flash Memory Update Utility requires creation of a
boot diskette and manual rebooting of the system. With 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 from a
CD-ROM disk.
This utility support the following BIOS maintenance functions:
• Verifies that the updated BIOS matches the target system to prevent accidentally installing an
incompatible BIOS.
• Updates both the BIOS boot block and the main BIOS. This process is fault tolerant to prevent
boot block corruption.
• Updates the BIOS boot block separately.
• Changes the language section of the BIOS.
• Updates replaceable BIOS modules, such as the video BIOS module.
• Inserts a custom splash screen.

✏

NOTE
Review the instructions distributed with the upgrade utility before attempting
a BIOS update.

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 of US English is used unless another language is selected in the BIOS Setup
program.

Intel Server Board S875WP1-E Product Guide

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.

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, the BIOS
recovery diskette must be a standard 1.44 MB diskette, not a 120 MB diskette.

Boot Options
In the BIOS Setup program, the user can choose to boot from a diskette drive, a hard drive, a
CD-ROM drive, 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.

CD-ROM and Network Boot
Booting from CD-ROM is supported in compliance with 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.

Server Board Features

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

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

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.

✏

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).

Intel Server Board S875WP1-E Product Guide

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:
• 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.

Emissions Disclaimer
To ensure EMC compliance with your local regional rules and regulations, the final configuration
of your end system product may require additional EMC compliance testing. For more information
please contact your local Intel Representative.
See “Regulatory and Integration Information” on page 107 for product Safety and EMC regulatory
compliance information. This is an FCC Class A device. Integration of it into a Class B chassis
does not result in a Class B device.

Warnings and Cautions
These warnings and cautions apply throughout this chapter. Only a technically qualified person
should configure the server board.

WARNING
Hazardous conditions, devices & cables: Hazardous electrical
conditions may be present on power, telephone, and communication cables.
Turn off the server and disconnect the power cord, telecommunications
systems, networks, and modems attached to the server before opening it.
Otherwise, personal injury or equipment damage can result.

Server Board Installation and Upgrades

CAUTIONS
System power on/off: The power button DOES NOT turn off the system
AC power. To remove power from system, you must unplug the AC power
cord from the wall outlet. Make sure the AC power cord is unplugged before
you open the chassis, add, or remove any components.
Electrostatic discharge (ESD) & ESD protection: ESD can damage
disk drives, boards, and other parts. We recommend that you perform all
procedures in this chapter only at an ESD workstation. If one is not
available, provide some ESD protection by wearing an antistatic wrist strap
attached to chassis groundany unpainted metal surfaceon your server
when handling parts.
ESD and handling boards: Always handle boards carefully. They can
be extremely sensitive to ESD. Hold boards only by their edges. After
removing a board from its protective wrapper or from the server, place the
board component side up on a grounded, static free surface. Use a
conductive foam pad if available but not the board wrapper. Do not slide
board over any surface.
Installing or removing jumpers: A jumper is a small plastic encased
conductor that slips over two jumper pins. Some jumpers have a small tab on
top that you can grip with your fingertips or with a pair of fine needle nosed
pliers. If your jumpers do not have such a tab, take care when using needle
nosed pliers to remove or install a jumper; grip the narrow sides of the
jumper with the pliers, never the wide sides. Gripping the wide sides can
damage the contacts inside the jumper, causing intermittent problems with
the function controlled by that jumper. Take care to grip, but not squeeze,
with the pliers or other tool you use to remove a jumper, or you may bend or
break the stake pins on the board.

Intel Server Board S875WP1-E Product Guide

Installing the I/O Shield
CAUTION
Systems based on the S875WP1-E server board need the I/O shield properly
installed to pass emissions (EMI) certification testing and to meet Class A
emissions compliance levels. Without the I/O shield, or with an improperly
installed I/O shield, the server system will not meet Class A regulatory
compliance requirements.
The boxed server board comes with an I/O shield for a general-purpose chassis. When installed in
the chassis, the shield blocks radio frequency transmissions, protects internal components from dust
and foreign objects, and promotes correct airflow within the chassis.
Install the I/O shield before installing the server board in the chassis. Place the shield inside the
chassis and press the shield into place so that it fits tightly and securely. If the shield does not fit,
obtain a proper-sized shield from the chassis supplier.

Installing and Removing Memory
The S875WP1-E server board contains four 184-pin DIMM sockets and supports up to four DDR
SDRAM DIMMs. The minimum supported memory configuration is 128 MB, using one DIMM in
DIMM socket 1A. The maximum configurable memory size is a 4 GB, using four 1 GB stacked
unbuffered DDR266/333/400 ECC DIMMs.
The silkscreen on the board for the DIMMs displays DIMM1A, DIMM2A, DIMM1B, and
DIMM2B, starting from the inside of the board. The DIMM1A is the socket closest to the
processor socket. One, two, or four DIMMs may be used at a time.
For dual-channel interleave, a minimum of two DIMMs must be installed and the DIMMs must be
populated as follows:
• DIMM1A and DIMM 1B: Populate these two sockets together first
• DIMM 2A and DIMM 2B: Populate these sockets in addition to DIMM 1A and DIMM 2A if
four DIMMs are to be used
When four DIMMs are installed, the system will use dual-channel interleave. For single-channel
memory, a single DIMM can be installed in socket DIMM 1A. For single-channel memory using
two DIMMs, populate the DIMM sockets in the following order:
• DIMM1A: Populate this socket if a single DIMM is to be installed
• DIMM2A: Populate this socket and the DIMM1A socket if two DIMMs are to be used

Connecting the IDE Cable
The Intel® boxed server board package includes a 40-contact, 80-conductor IDE cable. This cable is
capable of connecting two drives to the server board. The cable supports Ultra ATA/100/66 and
Ultra ATA/100 transfer protocols and is backward-compatible with drives using slower IDE
transfer protocols.

✏

NOTE
ATA-66/100 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 may be reduced to that of the slowest drive.
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.
For the cable to function correctly:
• Attach the end of the cable that has a single connector (A) to the server board as shown in
Figure 18. The connector at this end of the cable is black and is labeled PRI IDE.
• Attach the end of the cable that has two closely spaced connectors (B) to the drive(s). The
connectors at this end of the cable are gray and black and are labeled P2 and P3.
• If connecting only one IDE drive, connect the drive to the gray connector (P3).

3 Configuration Software and Utilities
This chapter tells you how to update the BIOS by with the Intel Flash Memory Update Utility, and
how to recover the BIOS if an update fails.

Updating the BIOS with the Intel® Flash Memory
Update Utility
With the Intel Flash Memory Update Utility you can update the system BIOS from a floppy disk or
other bootable media. The utility available from the Web provides a simple method for creating a
bootable flash memory update floppy that will automatically update your BIOS.
• Prepare for the update
• Update the BIOS
• Recover the BIOS if an update fails

Obtaining the BIOS Update File
You can update to a new version of the BIOS or change the language section of the BIOS by using
the BIOS update file. The BIOS update file is a compressed self-extracting archive that contains all
the files you need to update the BIOS. The BIOS update file contains:
• New BIOS files
• BIOS recovery files
• Intel Flash Memory Update Utility
You can obtain the BIOS update file through your server supplier or from the Intel World Wide
Web site:
http://support.intel.com/support/motherboards/server/

✏

NOTE
Review the instructions distributed with the update utility before attempting a
BIOS update.

Configuration Software and Utilities

✏

NOTE
Do not skip step 2. You will need these settings to configure your server at
the end of the upgrade procedure.
2. Write down the current settings in the BIOS Setup program.

Creating Bootable Media
You can create bootable media with a:
• CD writer
• Normal diskette drive or an LS-120 diskette drive
Creating a Bootable CD
The instructions below assume a bootable diskette is used. When using a CD writer to use a CD,
follow the instructions provided with your CD writer to make a bootable CD using floppy
emulation and bootable files.
Creating a Bootable Diskette

✏

NOTE
If your drive A is an LS-120 diskette drive, you must use a 1.44 MB diskette
as the bootable BIOS update diskette. The server is unable to recover a
BIOS from an LS-120 diskette.
To create a bootable diskette using a DOS system:
• Place an unformatted diskette in the diskette drive and format the diskette using the /s option.
Example: format a: /s
• Alternatively, place a formatted diskette in the diskette drive and use the sys command.
Example: sys a:
To create a bootable diskette using a non-DOS system:
1. Obtain the BIOS update file through your server supplier or from the Intel World Wide Web
site: http://support.intel.com/support/motherboards/server/
2. Copy the BIOS update file to a temporary directory on your hard disk.
3. Change to the temporary directory.
4. To extract the files, double click on the BIOS update file, for example, EABIOSxx.EXE.
5. One of the extracted files is MK_BOOTZ.EXE. Double click on this file to extract the
README.TXT file.
6. Follow the directions in the README.TXT file.

Intel Server Board S875WP1-E Product Guide

Creating a BIOS Update Media

Web site:
http://support.intel.com/support/motherboards/server/
2. Copy the BIOS update file to a temporary directory on your hard disk.
3. From the C:\ prompt, change to the temporary directory.
4. To extract the file, type the name of the BIOS upgrade file, for example, EABIOSxx.
5. Press . The extracted file contains the following files:
• LICENSE.TXT
• BIOINSTR.TXT
• BIOS.EXE
• MK_BOOTZ.EXE
6. Read the LICENSE.TXT file, which contains the software license agreement, and the
BIOINSTR.TXT file, which contains the instructions for the BIOS update.
7. Insert the bootable diskette into drive A.
8. Extract the BIOS.EXE file to the diskette. From the directory that contains the BIOS.EXE file
type:
BIOS A:
9. Press .
10. The diskette now holds the new BIOS files, the Intel Flash Update Utility, and the
recovery files.

Configuration Software and Utilities

Updating the BIOS
CAUTION
The AUTOEXEC.BAT file provided with the update files updates the BIOS
in two parts: first updating the boot block and displaying the Operation
completed successfully message and second, updating the BIOS core.
You will be asked to reboot the system when the update process is complete.
Do not interrupt the process or the system may not be capable of rebooting.
1. Boot the server with the bootable BIOS upgrade diskette in drive A. During system boot, the
AUTOEXEC.BAT file provided with the update files will automatically run the BIOS update
process.
The AUTOEXEC.BAT file updates the BIOS in two parts: first updating the boot block and
displaying the Operation completed successfully message and then updating the BIOS
core.
2. When the update process is complete, the monitor will display a message telling you to remove
the diskette and to reboot the system.
3. As the server boots, check the BIOS identifier (version number) to make sure the upgrade was
successful. If a logo appears, press to view the POST messages.
4. Enter BIOS Setup program by pressing when you see the message:
Press to Run SETUP

5.
6.
7.
8.
9.

For proper operation, load the BIOS Setup program defaults. To load the defaults, press .
To accept the defaults, press .
In Setup, enter the settings you wrote down before beginning the BIOS upgrade.
To save the settings, press .
To accept the settings, press .
Turn off the server and reboot.

Intel Server Board S875WP1-E Product Guide

Recovering the BIOS
It is unlikely that anything will interrupt the BIOS update, however, if an interruption occurs, the
BIOS could be damaged. The following steps explain how to recover the BIOS if an update fails.
The following procedure uses recovery mode for the Setup program. See page 58 for more
information on Setup modes.

✏

NOTE
Because of the small amount of code available in the boot block area, there is
no video support. You will not see anything on the screen during this
procedure. Monitor the procedure by listening to the speaker and looking at
the diskette drive LED.
1. Turn off the server, disconnect the server’s power cord, and disconnect all external peripherals.
2. Remove the server cover and locate the configuration jumper block (J8J2) (see Figure 22).
3. Remove the jumper from all pins as shown below to set recovery mode for Setup.
3

4. Insert the bootable BIOS update diskette into diskette drive A.
5. Replace the server cover, connect the power cord, turn on the server, and allow it to boot. The
recovery process will take a few minutes. Listen to the speaker and watch for drive A activity.
• Upon applying power, drive A will begin to show activity. In about a minute, two beeps are
heard and drive A activity ceases (temporarily) indicating the successful recovery of the
BIOS core. Drive A activity will begin again followed by two more beeps indicating the
successful recovery of the boot block. This sequence of events indicates that successful
BIOS recovery has taken place.
• A series of continuous beeps indicates that BIOS recovery has failed.
6. If recovery fails, return to step 1 and repeat the recovery process.
7. If recovery is successful, turn off the server, disconnect the power cord, and remove the server
cover.
8. On the jumper block (J8J2), reinstall the jumper back on pins 1-2 as shown below to set normal
mode for Setup.
3

9. Leave the update diskette in drive A, replace the server cover, and connect the server’s
power cord.
10. Turn on the server and continue with the BIOS update (see page 66).

Configuration Software and Utilities

Using the Setup Program
You can use the BIOS Setup program to change the configuration information and boot sequence
for the server. This chapter tells you how to access the BIOS Setup program and lists Setup
features, options, and default settings.

✏

NOTE
For reference purposes, you should write down the current Setup settings.
When you make changes to the settings, update this record.

BIOS Setup Program Modes
The BIOS Setup program has three modes of operation:
• Normal mode for normal operations
• Configure mode for clearing passwords (see Chapter 2 for instructions)
• Recovery mode for BIOS recovery
The BIOS Setup Program Operating mode is controlled by the setting of the configuration jumper
block. The jumper is set to normal mode at the factory. The Maintenance menu is not available
when Setup is used with the jumper in normal mode. The Maintenance menu is available only when
the BIOS configuration jumper covers pins two and three.
The BIOS Setup program can be used to view and change the BIOS settings for the server. The
BIOS Setup program is accessed by pressing the key after the Power-On Self-Test (POST)
memory test begins and before the operating system boot begins. The menu bar is shown below.

Server Board Connectors
CAUTION
Many of the baseboard and front panel connectors provide operating voltage
(+5 V DC and +12 V DC, for example) to devices inside the server chassis,
such as fans and internal peripherals. These connectors are not overcurrent
protected. Do not use these connectors for powering devices external to the
server chassis. A fault in the load presented by the external devices could
cause damage to the server, the interconnecting cable, and the external
devices themselves.

✏

NOTE
A standard ATX 20 pin power connector and standard ATX 12V 4 pin 2x2
connector can be used to power the server board S875WP1-E. 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.
