14 Intel Desktop Boards D815EEA2, D815EPEA2, D815EFV, and D815EPFV Product Guide Processors CAUTION Use only the processors listed below. Use of unsupported processors can damage the board, the processor, and the power supply. See the Intel Desktop D815EEA2/D815EPEA2 or D815EFV/D815EPFV Specification Update for the latest list of supported processors for thed815eea2, D815EPEA2, D815EFV, and D815EPFV boards. The boards support a single Intel Pentium III processor or Intel Celeron processor above 533 MHz. Processors are not included with the desktop board and must be purchased separately. The processor connects to the desktop board through a PGA370 socket. The boards support the processors listed in Table 4. Table 4. Processor Type Intel Pentium III processors Intel Celeron processors Supported Processors Socket Type FC-PGA FC-PGA Processor Frequency (GHz) Processor Frequency (MHz) , 866, 800EB, 733, 667, 600EB, and 533EB N/A 850, 800, 750, 700, 650, 600E, 550E, and 500E System Bus Frequency (MHz) N/A N/A 766, 733, 700, , 633, 600, 566, and 533A L2 Cache Size (KB) For the latest information on processor support for the boards, refer to the Intel desktop board Web site at: For instructions on installing or upgrading the processor, see Chapter 2. 14

15 Desktop Board Features Main Memory CAUTION 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. 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 boards supports 168-pin SDRAM DIMMs as defined below: 168-pin SDRAM Dual Inline Memory Modules (DIMMs) with gold-plated contacts Three DIMM slots are provided for flexible memory configurations 133 MHz SDRAM up to two double-sided DIMMs, or one double-sided DIMM and two single-sided DIMMs 100 MHz SDRAM up to three double-sided DIMMs Minimum system memory: 32 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 <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. 15

16 Intel Desktop Boards D815EEA2, D815EPEA2, D815EFV, and D815EPFV Product Guide Unbuffered single or double-sided DIMMs Serial Presence Detect (SPD) memory Non-ECC and ECC DIMMs (ECC DIMMs will operate in non-ecc mode only) 3.3 V memory (only) Suspend to RAM support Mixed speed DIMM configuration will default to the slowest speed DIMM installed. The board supports the processor and memory module combinations shown in Table 5. Table 5. Processor and Memory Module Combinations Processor Type (System Bus Frequency) PC100 Memory Modules PC133 Memory Modules Intel Celeron processor (66 MHz) will operate at 100 MHz will operate at 100 MHz Intel Celeron processor (100 MHz) will operate at 100 MHz will operate at 100 MHz Intel Pentium III processor (100 MHz) will operate at 100 MHz will operate at 100 MHz Intel Pentium III processor (133 MHz) will operate at 100 MHz will operate at 133 MHz (see note below) NOTES 100 MHz system bus frequency processors will support 133 MHz memory; however, the memory will operate at 100 MHz. For 133 MHz operation, only four sides of memory can be used; two double sided DIMMs, or one double sided DIMM and two single sided DIMMs. If more than four sides are used, the memory will only run at 100 MHz.

Audio drivers and utilities are available from Intel s World Wide Web site: 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 autoconfiguration 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 20
