Serial Ports  
The S845WD1-E server board has one serial port connector and one serial port header. The serial  
port A connector is located on the back panel. The serial port B header is located near the main  
power connector. The serial ports’ NS16C550-compatible UART supports data transfers at speeds  
up to 115.2 kb/s with BIOS support.  
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  
Diskette Drive Controller  
The I/O controller supports two diskette drives that are compatible with the 82077 diskette drive  
controller and supports both PC-AT and PS/2 modes.  
Keyboard and Mouse Interface  
PS/2 keyboard and mouse connectors are located on the back panel. The +5 V lines to these  
connectors are protected with a PolySwitchcircuit 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.  
The keyboard controller contains the AMI keyboard and mouse controller code, provides the  
keyboard and mouse control functions, and supports password protection for power-on/reset. A  
power-on/reset password can be specified in the BIOS Setup program.  
Hardware Management Subsystem  
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:  
Fan monitoring  
Thermal and voltage monitoring  
Chassis intrusion detection  
16  
Intel Server Board S845WD1-E Product Guide  
 
Hardware Management ASIC  
The Hardware Management ASIC provides low-cost instrumentation capabilities. The features of  
the component include:  
Internal ambient temperature sensing  
Remote thermal diode sensing for direct monitoring of processor temperature  
Power supply monitoring (+5 V, +3.3 V, +1.5 V, 3.3 VSB, and Vccp) to detect levels above or  
below acceptable values  
SMBus interface  
Fan Monitoring  
The Hardware Management ASIC provides four fan tachometer inputs. Monitoring can be  
implemented using Intel® LANDesk Client Manager or third-party software.  
Chassis Intrusion and Detection  
The S845WD1-E server board supports a chassis security feature that detects if the chassis cover is  
removed. 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.  
NOTE  
Chassis intrusion detection may be implemented using Intel LANDesk Client  
Manager or third-party software.  
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.

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.  
The S845WD1-E server board has four USB 1.1 ports; one USB peripheral can be connected to  
each port. For more than four USB devices, an external hub can be connected to any of the ports.  
Two of the USB ports are implemented with stacked back panel connectors; the other two are  
accessible via the front panel USB header. The S845WD1-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 shielded cable that meets the requirements for full-speed devices.  
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.

Intel Server Board S845WD1-E Product Guide  
 
IDE Support  
IDE Interfaces  
The ICH2’s IDE controller has two independent bus-mastering IDE interfaces that can be  
independently enabled. 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. 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 ICH2’s ATA-100  
logic can achieve transfer rates up to 100 MB/sec.  
NOTE  
ATA-66 and ATA-100 are faster timings and require 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 S845WD1-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.  
Description  
19  
 
BIOS  
The S845WD1-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 S845WD1-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 PT84510A.86B.  
When the S845WD1-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.  
PCI IDE Support  
If you select Auto in the BIOS Setup program, the BIOS automatically sets up the two  
PCI IDE connectors with independent I/O channel support. The IDE interface supports hard drives  
up to ATA-66/100 and recognizes any ATAPI compliant devices, including CD-ROM drives, tape  
drives, and Ultra DMA drives.  
The BIOS determines the capabilities of each drive and configures them to optimize capacity and  
performance. To take advantage of the high capacities typically available today, hard drives are  
automatically configured for Logical Block Addressing (LBA) and to PIO Mode 3 or 4, depending  
on the capability of the drive. You can override the auto-configuration options by specifying  
manual configuration in the BIOS Setup program.  
To use ATA-66/100 features the following items are required:  
An ATA-66/100 peripheral device  
An ATA-66/100 compatible cable  
ATA-66/100 operating system device drivers  
NOTE  
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.  
20  
Intel Server Board S845WD1-E Product Guide  
 
BIOS Updates  
The BIOS can be updated using either of the following utilities, which are available on the Intel  
World Wide Web site:  
Intel® Express BIOS update utility, which enables automated updating while in the Windows  
environment. Using this utility, the BIOS can be updated from a file on a hard disk, a 1.44 MB  
diskette, or a CD-ROM, or from the file location on the Web.  
Intel® Flash Memory Update Utility, which requires creation of a boot diskette and manual  
rebooting of the system. Using this utility, the BIOS can be updated from a file on a 1.44 MB  
diskette (from a legacy diskette drive or an LS-120 diskette drive) or a CD-ROM.  
Both utilities support the following BIOS maintenance functions:  
Verifying that the updated BIOS matches the target system to prevent accidentally installing an  
incompatible BIOS.  
Updating both the BIOS boot block and the main BIOS. This process is fault tolerant to prevent  
boot block corruption.  
Updating the BIOS boot block separately.  
Changing the language section of the BIOS.  
Updating replaceable BIOS modules, such as the video BIOS module.  
Inserting a custom splash screen.  
NOTE  
Review the instructions distributed with the upgrade utility before attempting  
a BIOS update.  
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.  
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.  
Description  
21  
 
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.  
22  
Intel Server Board S845WD1-E Product Guide  
 
Boot Options  
In the BIOS Setup program, the user can choose to boot from a diskette drive, hard drives,  
CD-ROM, or the network. The default setting is for the diskette drive to be the first boot device, the  
hard drive second, and the ATAPI CD-ROM third. The fourth device is disabled.  
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.  
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  
Description  
23  
 
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 IDE Configuration Submenu of the  
BIOS Setup program).

Intel Server Board S845WD1-E Product Guide  
 
BIOS Security Passwords  
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 <Enter> 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.

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.

Power Management Features  
Power management is implemented at several levels, including:  
Software support through Advanced Configuration and Power Interface (ACPI)  
Hardware support:  
Power connector  
Fan connectors  
LAN wake capabilities  
Instantly Available PC technology  
Resume on Ring  
Wake from USB  
Wake from PS/2 devices  
Power Management Event (PME#) wake-up support  
Wake on LAN Technology  
Network adapters that are PCI 2.2 compliant assert the wake-up signal using the PCI bus signal  
PME# (pin A19 on the PCI bus connectors).  
CAUTION  
For Wake on LAN 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 Wake on LAN  
technology can damage the power supply.  
CAUTION  
If the standby current necessary to support multiple wake events from the  
PCI and/or USB buses exceeds power supply capacity, the server board may  
lose register settings stored in memory, etc.  
Wake on Ring  
The operation of Wake on Ring can be summarized as follows:  
Powers up the server from the ACPI S5 state.  
Modem must support PME.  
Requires two calls to access the server:  
The first call powers up the server  
The second call enables access (when the appropriate software is loaded)  
For external modems, hardware on the server board monitors the ring indicate (RI) input of the  
serial port.  
Description  
27  
 
Resume on Ring  
The operation of Resume on Ring can be summarized as follows:  
Resumes operation from the ACPI S1.  
Requires only one call to access the server.  
Detects incoming call similarly for external and internal modems; does not use the Wake on  
Ring connector.  
Requires modem interrupt be unmasked for correct operation.  
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 S845WD1-E server board requires an operating  
system that provides full ACPI support.  
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 a front panel power and sleep mode switch

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 S845WD1-E board along with the associated system  
power targets. See the ACPI specification for a complete description of the various system and  
power states.

Hardware Support  
The S845WD1-E server board provides several power management hardware features, including:  
Power connector  
Fan connectors  
LAN wake capabilities  
Instantly Available PC technology  
Resume on Ring  
Wake from USB  
Wake from PS/2 keyboard  
PME# wake-up support  
LAN wake capabilities and Instantly Available PC technology require power from the +5 V  
standby line. The sections discussing these features describe the incremental standby power  
requirements for each.  
Resume on Ring enables telephony devices to access the computer when it is in a power-managed  
state. The method used depends on the type of telephony device (external or internal).  
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.  
NOTE  
The use of Resume on Ring and Wake from USB technologies from an ACPI  
state requires an operating system that provides full ACPI support.  
Description  
31  
 
Power Connector  
When used with an ATX12V or EPS-12 V compliant power supply that supports remote power  
on/off, the S845WD1-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.  
Fan Connectors

LAN Wake Capabilities  
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.  
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 Packetframe, the LAN subsystem asserts a wake-up signal that powers up  
the computer.  
Depending on the LAN implementation, the S845WD1-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  
32  
Intel Server Board S845WD1-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 S845WD1-E server board supports the PCI Bus Power Management Interface Specification.  
Add-in Board 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.  
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.

PCI I/O Subsystem  
The primary I/O bus for the S845WD1-E server board is PCI, with one independent PCI bus. The  
PCI bus complies with the PCI Local Bus Specification, Rev 2.2. The PCI bus is directed through  
the Intel 82801BA I/O Controller Hub (ICH2). The table below lists the characteristics of the  
PCI bus.

32-bit, 33-MHz PCI Subsystem  
All 32-bit, 33-MHz PCI I/O for the S845WD1-E server board is directed through the  
Intel 82801BA I/O Controller Hub (ICH2). The PCI bus supports the following embedded devices  
and connectors:  
2D/3D Graphics Accelerator: ATI Rage XL Video Controller.  
Two 10/100 Network Interface Controllers: Intel 82550PM Fast Ethernet Controller.  
ATA-100 controller: Promise Technology PDC20267.  
Two Ultra DMA 33 / ATA 66/100 connectors.  
Each of the embedded devices listed above, with exception to the Ultra DMA 33 / ATA 66/100  
connectors, will be allocated a GPIO to disable the device.  
Device IDs (IDSEL)  
Each device under the PCI hub bridge has its IDSEL signal connected to one bit of AD[31:16],  
which acts as a chip select on the PCI bus segment in configuration cycles. This determines a  
unique PCI device ID value for use in configuration cycles. The following table shows each  
IDSEL value for the PCI bus devices and the corresponding device description.

PCI Arbitration  
The PCI bus supports six PCI masters (ATI Rage XL, two Intel 82550s, Promise ATA-100  
Controller, PCI connector 1 and an arbiter (PCI connector 2 and PCI connector 3). All PCI masters  
must arbitrate for PCI access, using resources supplied by the ICH2. The host bridge PCI interface  
(ICH2) arbitration lines REQx and GNTx are a special case in that they are internal to the host  
bridge.  
ATA-100  
The S845WD1-E server board provides an embedded dual channel ATA-100 bus through the use  
of the Promise Technology PDC20267 ASIC. The PDC20267 ATA-100 controller contains two  
independent ATA-100 channels that share a single 32-bit, 33-MHz PCI bus master interface as a  
multifunction device, packaged in a 128-pin PQFP.  
The ATA-100 controller supports the following features:  
The scatter / gather mechanism supports both Direct Memory Access (DMA) and  
Programmable I/O (PIO) IDE drives and ATAPI devices.  
Support for ATA and ATAPI proposal PIO Mode 0, 1, 2, 3, 4, DMA Mode 0, 1, 2, and  
Ultra DMA Mode 0, 1, 2, 3, 4, 5.  
The IDE drive transfer rate is capable of up to 100 MB/sec per channel.  
The host interface complies with PCI Local Bus Specification Revision 2.2.  
32-bit, 33-MHz bus speed and 132 MB/sec sustained transfer rate.  
The Promise PDC20267 supports IDE RAID through dual ATA-100 Channels. In a RAID  
configuration, multiple IDE 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 IDE RAID can be configured as follows:  
RAID 0: Striping one to four drives.  
RAID 1: Mirroring two drives.  
RAID 1 +: Spare drive (three drives).  
RAID 0 +: One to four drives are required.  
RAID 0 configurations are used for high-performance applications, as it doubles the sustained  
transfer rate of its drives. RAID 1 configurations 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 dual ATA-100 channels, two striped drive pairs can mirror each other (RAID 0+1) for  
storage capacity and data redundancy.

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 93 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.  
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.  
41  
 
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 groundany unpainted metal surfaceon 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 with, but not  
squeeze, the pliers or other tool you use to remove a jumper, or you may  
bend or break the stake pins on the board.

Installing the I/O Shield  
CAUTION  
Systems based on the S845WD1-E server board need the I/O shield properly  
installed to pass emissions (EMI) certification testing and to meet Class B  
emissions compliance levels. Without the I/O shield, or with an improperly  
installed I/O shield, the server system will not meet Class B regulatory  
compliance requirements.  
The boxed server board comes with an I/O shield for a general purpose chassis. If installing this  
board in an 1U chassis, obtain an I/O shield from the chassis vendor. 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 doesn’t fit,  
obtain a proper-sized shield from the chassis supplier.

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 54 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 (J6H1) (see Figure 14).  
3. Remove the jumper from all pins as shown below to set recovery mode for Setup.  
3
1
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, and disconnect its power cord.  
8. Remove the server cover and continue with the following steps.  
9. On the jumper block (J6H1), reinstall the jumper back on pins 1-2 as shown below to set  
normal mode for Setup.

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.  
NOTE  
The Setup menus described in this section apply to the server boards with  
BIOS identifier WD845.10A.86B. Server boards with other BIOS identifiers  
might have differences in some of the Setup menu screens.  
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 <F2> 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.
