The D810E2CB board supports processors that draw a maximum of 22 A. Using a processor that draws more than 22 A can damage the processor, the board, and the power supply. See the processor’s data sheet for current usage requirements.

CAUTION

Before installing or removing the processor, make sure that AC power has been removed by unplugging the power cord from the computer. Failure to do so could damage the processor and the board.

The D810E2CB board supports either an Intel PentiumIII processor (FCPGA package), or an Intel Celeron processor (PGA package) as shown in Table 4. The system bus frequency is automatically selected.

1.5 System Memory

NOTE

✏

To be compliant with applicable Intel®SDRAM memory specifications, the D810E2CB board should be populated with DIMMs that support the Serial Presence Detect (SPD) data structure. If your memory modules do not support SPD, the BIOS will attempt to configure the memory controller for normal operation; however, the DIMMs may not function at their optimum speed.

CAUTION

Before installing or removing memory, make sure that AC power has been removed by unplugging the power cord from the computer. Failure to do so could damage the memory and the board.

CAUTION

Because the main system memory is also used as video memory, the board r equires 100 MHz SDRAM DIMMs even though the processor’s system bus speed is 66 MHz. It is highly recommended that SPD DIMMs 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 nonSPD memory is installed, the BIOS will attempt to correctly configure the memory settings, but performance and reliability may be impacted.

The D810E2CB board has two DIMM sockets. The minimum memory size is 64 MB and the maximum memory size is 512 MB. The BIOS automatically detects memory type, size, and speed. Memory can be installed in one or both sockets. Memory size can vary between sockets.

The D810E2CB board supports the following memory features:

• 3.3 V, 168-pin DIMMs with gold-plated contacts

• 100 MHz SDRAM

• Serial Presence Detect (SPD) or non-SPD memory (BIOS recovery requires SPD DIMMs)

• Non-ECC (64-bit) memory

• Unbuffered single- or double-sided DIMMs

The board is designed to support DIMMs in the configurations listed in Table 5 below.

1.6.1 Direct AGP

Direct (integrated) AGP is a high-performance bus (independent of the PCI bus) for graphicsintensive applications, such as 3D applications. AGP overcomes certain limitations of the PCI bus related to handling large amount of graphics data with the following features:

• Pipelined memory read and write operations that hide memory access latency

• Demultiplexing of address and data on the bus for nearly 100 percent bus efficiency

Accelerated Graphics Port Interface Specification

Table 3, page 16

1.6.2 USB

The ICH2 contains two separate USB controllers supporting four USB 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 connector at location J8B1. The D810E2CB board fully supports Universal Hub Controller Interface (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.

Product Description

1.6.3 IDE Support

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 rat es of up to 16 MB/sec.

• Ultra DMA: DMA protocol on IDE bus supportinghost and target throttling a nd transfer rates

of up to 33 MB/sec.

• Ultra ATA-66: DMA protocolon 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.

• Ultra ATA-100: DMA protocolon IDE bus allows host and target throttling. The ICH2 Ultra

ATA-100 logic can achieve read transfer rates up to 100 MB/sec and write transfer rates up to 88 MB/sec.

✏ NOTE

ATA-100 and ATA-66 use 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 Section 4.4.4.1 on page 91.

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 D810E2CB board supports laser servo (LS-120) diskette technology through its 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)

1.6.4 Real-Time Clock, CMOS SRAM, and Battery

The real-time clock is compatiblewith DS1287 and MC146818 components. The clockprovides a time-of-day clock and a multicentury calendar with alarm features and century rollover. The realtimeclock supports 256 bytes of battery-backed CMOS SRAM in two banks that are reservedfor BIOS use.

A coin-cell battery 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 3.3 V 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, the last saved defaults, custom or standard, will be loaded into CMOS SRAM at power on.

NOTE

✏

The recommended method of accessing the date in systems with Intel®desktop boards is indirectly from the Real-Time Clock (RTC) via the BIOS. The BIOS on Intel desktop boards contains a century checking and maintenance feature. This feature checks the two least significant digits of the year stored in the RTC during each BIOS request (INT 1Ah) to read the date and, if less than 80 (i.e., 1980 is the first year supported by the PC), updates the century byte to 20. This feature enables operating systems and applications using the BIOS date/time services to reliably manipulate the year as a four-digit value.
