1.6 System Memory
CAUTION
Before installing or removing memory, make sure that AC power is disconnected by unplugging
the power cord from the computer. Failure to do so could damage the memory and the board.
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.
However, DIMMs may not function under the determined frequency.
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 D815EGEW board has two DIMM sockets and supports the following memory features:
• 3.3 V (only) 168-pin SDRAM DIMMs with gold-plated contacts
• Unbuffered single-sided or double-sided DIMMs
• Capacity:
Maximum system memory: 512 MB
Minimum system memory: 64 MB
• 133 MHz SDRAM or 100 MHz SDRAM
• Serial Presence Detect (SPD) and non-SPD memory
• Non-ECC and ECC DIMMs (ECC DIMMs will operate in non-ECC mode only)
• Suspend to RAM
When installing memory, note the following:
• Non-SPD DIMMs will always revert to a 100 MHz with 3-3-3 timing SDRAM bus.
• Mixing Non-SPD DIMMs with SPD DIMMs will always revert to a 100 MHz with 3-3-3
timing SDRAM bus.
• The BIOS will not initialize installed memory above 512 MB. At boot, the BIOS displays a
message indicating that any installed memory above 512 MB has not been initialized.
• Mixed memory speed configurations (133 and 100 MHz) will default to 100 MHz.
• 133 MHz SDRAM operation requires a 133 MHz system bus frequency processor.
• 100 MHz SDRAM may be populated with four rows of SDRAM (two double-sided DIMMs).

Product Description
1.7.1 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): CPU controls data transfer.
• 8237-style DMA: DMA offloads the CPU, 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 ATA-100
logic can achieve read transfer rates up to 100 MB/sec and write transfer rates up to
88 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 listed in Table 64 on page 95.
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 D815EGEW board supports Laser Servo (LS-120) diskette technology through its IDE
interfaces. The 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)
For information about Refer to
The location of the IDE connectors Figure 9, page 54
The signal names of the IDE connectors Table 37, page 56
BIOS Setup program’s Boot menu Table 71, page 103
1.7.2 USB
The D815EGEW board has two USB ports; one USB peripheral can be connected to each port.
For more than two USB devices, an external hub can be connected to any of the ports. The
D815EGEW board’s two USB ports are implemented with stacked back panel connectors, routed
through the ICH2. The board contains a jumper block for enabling/disabling the Wake from USB
feature.
The D815EGEW board fully supports the Universal Hub Controller Interface (UHCI).
23
Intel Desktop Board D815EGEW Technical Product Specification
NOTE
✏
Computer systems that have an unshielded cable attached to a USB port may not meet FCC
Class B requirements, even if no device or a low-speed USB device is attached to the cable. Use
shielded cable that meets the requirements for full-speed devices.
For information about Refer to

The signal names of the back panel USB connectors Table 20, page 47
The USB specification and UHCI Table 3, page 17
The Wake from USB jumper block Section 2.9, page 61
1.7.3 Real-Time Clock, CMOS SRAM, and Battery
The real-time clock provides a time-of-day clock and a multicentury 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
SRAM at power-on.
1.8 I/O Controller
The D815EGEW board includes the National Semiconductor PC87360 I/O controller. The I/O
controller’s features include:
• Low pin count (LPC) interface
• 3.3 V operation
• One serial port
• One parallel port with Extended Capabilities Port (ECP) and Enhanced Parallel Port
(EPP) support
• PS/2-style mouse and keyboard interfaces
• Interface for one 1.2 MB, 1.44 MB, or 2.88 MB diskette drive
• One fan control output
The BIOS Setup program provides configuration options for the I/O controller.

115.2 kbits/sec with BIOS support. The serial port can be assigned as COM1 (3F8h), COM2
(2F8h), COM3 (3E8h), or COM4 (2E8h).

1.8.2 Parallel Port
The connector for the parallel port is a 25-pin D-Sub connector located on the back panel. In the
BIOS Setup program, the parallel port can be set to the following modes:
†
• Output only (PC AT
• Bi-directional (PS/2 compatible)
• EPP
• ECP

1.8.3 Diskette Drive Controller
The I/O controller supports one diskette drive that is compatible with the 82077 diskette drive
controller and supports both PC-AT and PS/2 modes.
For information about Refer to
The location of the diskette drive connector Figure 9, page 54

The supported diskette drive capacities and sizes Table 65, page 97
1.8.4 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 thermistor, which limits the current to a specified amperage.
NOTE
✏
The keyboard and mouse will function in either PS/2 connector, but the connectors are colorcoded for ease of installation. 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.
25
Intel Desktop Board D815EGEW Technical Product Specification
The keyboard controller also supports the hot-key sequence <Ctrl><Alt><Del> for a software reset
(operating system dependent). This key sequence resets the computer’s software by jumping to the
beginning of the BIOS code and running the power-on self-test (POST).
The board contains a jumper block for enabling/disabling the Wake from PS/2 feature.
