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 double-
sided 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.

1.8 Chipsets
This section describes the chipsets used by the D815EEA2 and D815EPEA2 boards:
• The D815EEA2 board uses the Intel 815E Chipset, described below.
• The D815EPEA2 board uses the Intel 815EP Chipset, described in Section 1.8.2, beginning on
page 31.
1.8.1 Intel® 815E Chipset
The Intel 815E chipset consists of the following devices:
• 82815 Graphics and Memory Controller Hub (GMCH) with Accelerated Hub Architecture
(AHA) bus
• 82801BA I/O Controller Hub (ICH2) with AHA bus
• SST 49LF004A Firmware Hub (FWH)
The GMCH is a centralized controller for the system bus, the memory bus, the AGP bus, and the
AHA bus. The ICH2 is a centralized controller for the board’s I/O paths. The FWH provides the
nonvolatile storage of the BIOS.
The Intel 815E chipset provides the interfaces shown in Figure 5.

Product Description
1.8.1.1 Intel® 82815 Graphics and Memory Controller Hub (GMCH)
The GMCH provides the following:
• An integrated Synchronous DRAM memory controller with autodetection of SDRAM
• An interface for a single AGP device or a Graphics Performance Accelerator (GPA) card
• An interface for an optional digital video output (DVO) connector for a flat panel, digital CRT,
or TV-out
• Support for ACPI Rev. 2.0 and APM Rev. 1.2 compliant power management
1.8.1.2 Intel® 82801BA I/O Controller Hub (ICH2)
The ICH2 provides the following:
• 33 MHz PCI bus interface
• Support for up to six PCI master devices
• Low Pin Count (LPC) interface that supports an LPC-compatible I/O controller
• Support for two Master/DMA devices
• Integrated IDE controller that supports Ultra DMA (33 MB/sec) and ATA-66/100 mode
(66 MB/sec, 100 MB/sec)
• Integrated LAN Media Access Controller
• Universal Serial Bus interface with two USB controllers providing four ports in a
UHCI Implementation (additional USB ports provided with the optional SMSC
LPC47M142 I/O controller)
• Power management logic for ACPI Rev. 1.0b compliance
• System Management Bus (SMBus clock and data lines also routed to PCI bus connector 2)
• Real-time clock with 256-byte battery-backed CMOS RAM
• AC ’97 digital link for audio codec, including:
AC ’97 2.1 compliance
Logic for PCM in, PCM out, and mic input
PCI functions for audio
Communication and Network Riser (CNR) interface
1.8.1.2.1 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.
27
Intel Desktop Board D815EEA2/D815EPEA2 Technical Product Specification
The IDE interfaces also support ATAPI devices (such as CD-ROM drives) and ATA devices using
the transfer modes listed in Table 71 on page 121.
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 D815EEA2 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 15, page 73
The signal names of the IDE connectors Table 43, page 77
BIOS Setup program’s Boot menu Section 4.7, page 130
1.8.1.2.2 USB
The ICH2 contains two separate USB controllers. The D815EEA2 board has 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. The D815EEA2 board fully supports the Universal Hub
Controller Interface (UHCI).
In the standard configuration, the D815EEA2 board’s four USB ports are implemented with stacked
back panel connectors, routed through the ICH2, as shown in Figure 6.
With the optional SMSC LPC47M142 I/O controller, the D815EEA2 board supports up to seven
USB ports. The SMSC LPC47M142 I/O controller provides four ports: two ports implemented
with stacked back panel connectors and two ports routed to the optional front panel USB connector
at location J8F1. The ICH2 provides three ports: two ports are implemented with stacked back
panel connectors and the other port is accessible through a CNR add-in card, as shown in Figure 6.
The D815EEA2 board fully supports the Universal Hub Controller Interface (UHCI).

Intel Desktop Board D815EEA2/D815EPEA2 Technical Product Specification
1.8.1.2.3 Real-Time Clock, CMOS SRAM, and Bat t e ry
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.
1.8.1.3 SST 49LF004A 4 Mbit Firmware Hub (FWH)
The system BIOS is stored in the FWH.
