Desktop Board Features
Main Memory
NOTE
✏
To be fully compliant with all applicable Intel® SDRAM memory specifications, the board should
be populated with DIMMs that support the Serial Presence Detect (SPD) data structure. If your
memory modules do not support SPD, you will see a notification to this effect on the screen at
power up. The BIOS will attempt to configure the memory controller for normal operation at
100 MHz.
NOTE
✏
Because the main system memory is also used as video memory, the board requires a 100 MHz
SDRAM DIMM even though the host bus frequency is 66 MHz. It is highly recommended that an
SPD DIMM be used, since this allows the BIOS to read the SPD data and program the chipset to
accurately configure memory settings for optimum performance. If non-SPD memory is installed,
the BIOS will attempt to correctly configure the memory settings, but performance and reliability
may be impacted.
The board supports memory as defined below:
• Two 3.3 V, 168-pin SDRAM Dual Inline Memory Modules (DIMMs) with gold-plated
contacts
• Unbuffered single or double-sided DIMM configurations
• 100 MHz PC100 SDRAM (all FSB frequencies)
• 133 MHz PC133 SDRAM (only supported with 133 MHz system bus frequency)
• Minimum system memory: 64 MB
• Maximum system memory: 512 MB
NOTE
✏
The BIOS cannot determine DIMM size or type when not initialized. If more than 512 MB system
memory is installed, the BIOS displays a message at boot indicating memory above 512 MB has
not been initialized. The message indicates that additional information is available in Setup. The
first time the BIOS detects this condition, a pause follows the message with the option to enter
Setup or to press <ESC> and continue to boot. The message continues to be displayed at boot
time as long as the condition exists, however, the BIOS will not pause on subsequent detection.
Setup displays the installed memory configuration and shows memory above 512 MB as “not
initialized.”
• Basic non-SPD at 100 MHz
• Suspend to RAM support
• Mixed speed DIMM configuration will default to the slowest speed DIMM installed.

Desktop Board Features
BIOS
The BIOS provides the Power-On Self-Test (POST), the BIOS Setup program, the PCI and IDE
auto-configuration utilities, and the video BIOS. The BIOS is stored in the Firmware Hub.
The BIOS can be upgraded by following the instructions in Chapter 3.
PCI Auto Configuration
If you install a PCI add-in board in your computer, the PCI auto-configuration utility in the BIOS
automatically detects and configures the resources (IRQs, DMA channels, and I/O space) for that
add-in board. You do not need to run the BIOS Setup program after you install a PCI add-in
board.
IDE Auto Configuration
If you install an IDE device (such as a hard drive) in your computer, the IDE auto-configuration
utility in the BIOS automatically detects and configures the device for your computer. You do not
need to run the BIOS Setup program after installing an IDE device. 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

Security Passwords
The BIOS includes security features that restrict whether the BIOS Setup program can be accessed
and who can boot the computer. A supervisor password and a user password can be set for the
Setup and for booting the computer, 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 computer. The password prompt is
displayed before the computer is booted. If only the supervisor password is set, the computer
boots without asking for a password. If both passwords are set, you can enter either password
to boot the computer.
Speaker
A 47 Ω inductive speaker is mounted on the desktop boards. The speaker provides audible error
code (beep code) information during the Power-On Self-Test (POST).
Battery
A battery on the desktop board keeps the values in CMOS RAM and the clock current when the
computer is turned off. See Chapter 2 for instructions on how to replace the battery.

Power Management Features
Power management is implemented at several levels, including:
• Software support:
Advanced Power Management (APM)
Advanced Configuration and Power Interface (ACPI)
• Hardware support:
Power connector
Fan connectors
Instantly Available technology ACPI S3 state (must be enabled in BIOS under the Power
menu)
S5 wake on PCI bus connector 2 only
Wake from USB (see page 35 for information on how to set the jumper blocks)
Wake from keyboard/mouse (see page 35 for information on how to set the jumper blocks)
Wake on PME
Resume on Ring
Desktop Board Features
If the board is used with an ACPI-aware operating system, the BIOS can provide ACPI support.
Otherwise, it defaults to APM support.
Instantly Available Technology
CAUTION
For Instantly Available 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
using this feature can damage the power supply and/or affect ACPI S3 sleep state functionality.
CAUTION
If the standby current necessary to support multiple wake events from the PCI and/or USB buses
exceeds power supply capacity, the desktop board may lose register settings stored in memory.
Instantly Available technology enables the board to enter the ACPI S3 (Suspend-to-RAM) sleep
state. While in the S3 sleep state, the computer will appear to be off. When signaled by a wake-up
device or event, the system quickly returns to its last known awake state.
The board’s standby power indicator, shown in Figure 2, is lit when there is standby power to the
system. This includes the memory modules and PCI bus connectors even when the computer
appears to be off.
If the system has a dual-colored power LED on the front panel, the sleep state is indicated by the
LED turning amber.

Figure 2. Location of the Standby Power Indicator
Power supplies used with this board must be able to provide enough standby current to support the
standard Instantly Available (ACPI S3 sleep state) configuration as outlined in Table 5. Values are
determined by specifications such as PCI 2.2. Actual measurements may vary.
To estimate the total amount of standby current required for a particular system configuration,
standby current requirements of all installed components must be added. Refer to the descriptions
in Table 5 and follow the steps outlined below:
1. Note the total D815EGEW board standby current requirement.
2. Add to that the total PS/2 port standby current requirement if a wake-enabled device is
connected.
3. Add, from the PCI 2.2 slots (wake-enabled) row, the total of the number of wake-enabled
devices installed (PCI) multiplied by the standby current requirement.
4. Add, from the PCI 2.2 slots (nonwake-enabled) row, the total of the number of wake-enabled
devices installed (PCI) multiplied by the standby current requirement.
5. Add all additional wake-enabled devices’ and nonwake-enabled devices’ standby current
requirements as applicable.
6. Add all the required current totals from steps 1 through 5 to determine the total estimated
standby current power supply requirement.

Resume on Ring
The operation of Resume on Ring can be summarized as follows:
• Resumes operation from either the APM sleep mode or the ACPI S1 state
• 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
