circuit that, like a self-healing fuse, reestablishes the

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.

Description 17

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.

18 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.

BIOS Updates

The BIOS can be updated using either of the following utilities, which are available on the Intel World Wide Web site:

• Intel

Both utilities support the following BIOS maintenance functions:

• Verifying that the updated BIOS matches the target system to prevent accidentally installing an

• Updating both the BIOS boot block and the main BIOS. This process is fault tolerant to prevent

• 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.

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.

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.

incompatible BIOS.

boot block corruption.

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).

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 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 multiple wake-up events (see Table 7. Wake-up Devices and Events, page30)

• Support for a front panel power and sleep mode switch

28 Intel Server Board S845WD1-E Product Guide

Table 5 lists the system states based on how long the power switch is pressed, depending on how ACPI is configured with an ACPI-aware operating system.

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.
