For information about Product information on supported processors Processor data sheets Refer to Section 1.3, page 19 Section 1.3, page 19 23 Intel Desktop Board D815EEA2/D815EPEA2 Technical Product Specification 1.7 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 Remove the AGP video card before installing or upgrading memory to avoid interference with the memory retention mechanism. 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. 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 or the DIMMs may not function under the determined frequency. The D815EEA2 and D815EPEA2 boards both have three DIMM sockets and support the following memory features: · 3.3 V (only) 168-pin SDRAM DIMMs with gold-plated contacts · Unbuffered single-sided or double-sided DIMMs · Maximum total system memory: 512 MB; minimum total 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. · 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. · The board should be populated with no more than four rows of 133 MHz SDRAM (two doublesided or one double-sided plus two single-sided DIMMs). · 100 MHz SDRAM may be populated with six rows of SDRAM (three double-sided DIMMs). NOTE At boot, the BIOS displays a message indicating that any installed memory above 512 MB has not been initialized. 24 Product Description NOTE If more than four rows of 133 MHz SDRAM are populated, the BIOS will display a message indicating that it will initialize installed memory up to 512 MB at 100 MHz. For information about Obtaining the PC Serial Presence Detect (SPD) Specification Refer to Table 4, page 19 Table 6 lists the supported DIMM configurations. Table 6.

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. 1.8.2.3 SST 49LF004A 4 Mbit Firmware Hub (FWH) The system BIOS is stored in the FWH. 35 Intel Desktop Board D815EEA2/D815EPEA2 Technical Product Specification 1.9 I/O Controller The D815EEA2 and D815EPEA2 boards support either of two I/O controllers: · The standard SMSC LPC47M132 I/O controller or · The optional SMSC LPC47M142 I/O controller Both I/O controllers provide the following features: · Low pin count (LPC) interface · 3.3 V operation · Two serial ports · One parallel port with Extended Capabilities Port (ECP) and Enhanced Parallel Port (EPP) support · Serial IRQ interface compatible with serialized IRQ support for PCI systems · PS/2-style mouse and keyboard interfaces · Interface for one 1.2 MB, 1.44 MB, or 2.88 MB diskette drive · Intelligent power management, including a programmable wake up event interface · PCI power management support · Fan control One fan control output Two fan tachometer inputs The optional SMSC LPC47M142 I/O controller provides an additional USB hub. The BIOS Setup program provides configuration options for the I/O controller. For information about The USB hubs on the D815EEA2 board The USB hubs on the D815EPEA2 board SMSC LPC47M132 and LPC47M142 I/O controllers Refer to Section 1.8.1.2.2, page 28 Section 1.8.2.2.2, page 33 http://www.smsc.com 1.9.1 Serial Ports The D815EEA2 and D815EPEA2 boards each have two serial ports. Serial port A is located on the back panel. Serial port B is accessible using the connector at location J8H1. The serial ports' NS16C550-compatible UARTs support data transfers at speeds up to 115.2 kbits/sec with BIOS support. The serial ports can be assigned as COM1 (3F8h), COM2 (2F8h), COM3 (3E8h), or COM4 (2E8h). For information about The location of the serial port A connector The signal names of the serial port A connector The location of the serial port B connector The signal names of the serial port B connector Refer to Figure 13, page 64 Table 24, page 66 Figure 16, page 78 Table 44, page 79 36 Product Description 1.9.2 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-compatible mode) · Bi-directional (PS/2 compatible) · EPP · ECP For information about The location of the parallel port connector The signal names of the parallel port connector Setting the parallel port's mode Refer to Figure 13, page 64 Table 23, page 65 Table 69, page 118 1.9.3 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 The location of the diskette drive connector The signal names of the diskette drive connector The supported diskette drive capacities and sizes Refer to Figure 15, page 73 Table 42, page 77 Table 72, page 123 1.9.4 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
