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).

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)

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.

✏

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.

NOTE

✏

Wake up from PS/2 mouse is peripheral, operating system, and driver dependent.

1.13.1.1.3 Plug and Play

In addition to power management, ACPI provides controls and information so that the operating system can facilitate Plug and Play device enumeration and configuration. ACPI is used only to enumerate and configure D815EGEW board devices that do not have other hardware standards for enumeration and configuration. PCI devices on the D815EGEW board, for example, are not enumerated by ACPI.

1.13.2 Hardware Support

CAUTION

If the Wake on LAN and Instantly Available technology features are used, ensure that the power supply provides adequate +5 V standby current. 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. Refer to Section 2.11.3 on page 68 for additional information.

The boards provides several hardware features that support power management, including:

• Power connector

• Fan connectors

• Wake on LAN technology connector (optional)

• Instantly Available technology

• Resume on Ring

• Wake from USB

• Wake from PS/2 keyboard

• PME# wakeup support

Wake on LAN technology and Instantly Available 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).

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.

1.13.2.1 Power Connector

When used with an ATX-compliant power supply that supports remote power on/off, the D815EGEW board can turn off the system power through software control. To enable soft-off control in software, power management must be enabled in the BIOS Setup program and in the operating system. 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 Power menu.

For information about Refer to

The location of the power connector Figure 8, page 51

The signal names of the power connector Table 31, page 52

The BIOS Setup program’s Power menu Section 4.6, page 101

The ATX specification Table 3, page 17

1.13.2.2 Fan Connectors

The D815EGEW board has two fan connectors. The functions of these connectors are described in Table 11.

Table 11. Fan Connector Descriptions

Connector Function

Processor fan (fan 1) Provides +12 V DC for a processor fan or active fan heatsink.

Optional chassis fan (fan 2)

Provides +12 V DC for a system or chassis fan. The fan voltage can be switched on or off, depending on the power management state of the computer.

1.13.2.3 Wake on LAN Technology (Optional)

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. Refer to Section 2.11.3 on page 68 for additional information.

Product Description

NOTE

✏

The Wake on LAN technology connector is present only on boards that do not have the Intel 82562ET PLC device, which is part of the optional onboard LAN subsystem.

Wake on LAN technology enables remote wakeup 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 wakeup signal that powers up the computer. Depending on the LAN implementation, the D815EGEW board supports Wake on LAN technology in the following ways:

• Through the Wake on LAN technology connector

• Through the PCI bus PME# signal for PCI 2.2 compliant LAN designs (ACPI only)

• Through the onboard LAN subsystem when enabled in Setup (ACPI only)

The optional Wake on LAN technology connector can be used with PCI bus network adapters that have a remote wake up connector, as shown in Figure 5. Network adapters that are PCI 2.2 compliant assert the wakeup signal through the PCI bus signal PME# (pin A19 on the PCI bus connectors).

1.13.2.4 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 implementing Instantly Available technology can damage the power supply. Refer to Section 2.11.3 on page 68 for additional information.

Instantly Available technology enables the D815EGEW board to enter the ACPI S3 (suspend-toRAM) sleep-state. While in the S3 sleep-state, the computer will appear to be off (the power supply is off, the fans are off, and the front panel LED is amber if dual-color, or off if single-

color.) When signaled by a wake-up device or event, the system quickly returns to its last known wake state.

The D815EGEW board supports the PCI Bus Power Management Interface Specification. Add-in boards that also support this specification can participate in power management and can be used to wake the computer.

The use of Instantly Available technology requires operating system support and PCI 2.2 compliant add-in cards and drivers.

The optional standby power indicator LED shows that power is still present at the DIMM and PCI bus connectors, even when the computer appears to be off. Figure 6 shows the location of the optional standby power indicator LED on the D815EGEW.
