Page 50: Power States And Targeted System Power
The operating system uses information from applications and user settings to put the system as a whole into a low-power state. Table 10 lists the power states supported by the D815EEA2 and D815EPEA2 boards along with the associated system power targets. See the ACPI specification for a complete description of the various system and power states.
Page 51: Wake Up Devices And Events
For the Wake on LAN technology connector and PME#, S5 is disabled by default in the BIOS Setup program. Setting these options to Power On will enable a wake-up event from LAN in the S5 state. Wake from CNR modem is not supported on the D815EEA2 and D815EPEA2 boards. NOTE The use of these wake up events from an ACPI state requires an operating system that provides full ACPI support.
Page 52: Hardware Support
When used with an ATX-compliant power supply that supports remote power on/off, the D815EEA2 and D815EPEA2 boards can turn off the system power through software control. To enable soft-off control in software, advanced power management must be enabled in the BIOS Setup program and in the operating system.

2.10 Mechanical Considerations 2.10.1 Form Factor The D815EEA2 and D815EPEA2 boards are designed to fit into a standard ATX-form-factor chassis. Figure 18 illustrates the mechanical form factor for the D815EEA2 and D815EPEA2 boards. Dimensions are given in inches [millimeters]. The outer dimensions are 11.55 inches by 8.20 inches [293.37 millimeters by 208.28 millimeters].
Page 85: I/O Shields
Technical Reference 2.10.2 I/O Shields The back panel I/O shields for the D815EEA2 and D815EPEA2 boards must meet specific dimension and material requirements. Systems based on this board need the back panel I/O shield to pass emissions (EMI) certification testing. Figure 19, Figure 20, and Figure 21 show the critical dimensions of the chassis-dependent I/O shield for the Universal boards.

Page 96: Thermal Considerations
System integrators should ensure that proper airflow is maintained in the voltage regulator circuit. Failure to do so may result in damage to the voltage regulator circuit. Figure 25 shows the locations of the localized high temperature zones for the D815EEA2 and D815EPEA2 boards.
Page 97: Reliability
Technical Reference Table 56 provides maximum case temperatures for D815EEA2 and D815EPEA2 board components that are sensitive to thermal changes. Case temperatures could be affected by the operating temperature, current load, or operating frequency. Maximum case temperatures are important when considering proper airflow to cool the D815EEA2 and D815EPEA2 boards.

Page 101: Overview Of Bios Features
3.10 BIOS Security Features ....................109 3.1 Introduction The D815EEA2 and D815EPEA2 boards use an Intel/AMI BIOS that is stored in the Firmware Hub (FWH) and can be updated using a disk-based program. The FWH contains the BIOS Setup program, POST, APM, the PCI auto-configuration utility, and Plug and Play support.
Page 102: Bios Flash Memory Organization
Intel Desktop Board D815EEA2/D815EPEA2 Technical Product Specification 3.2 BIOS Flash Memory Organization The FWH (an SST 49LF004A) includes a 4 Mbit (512 KB) symmetrical flash memory device. Internally, the device is grouped into eight 64-KB blocks that are individually erasable, lockable, and unlockable.

Intel Desktop Board D815EEA2/D815EPEA2 Technical Product Specification 3.5 Legacy USB Support Legacy USB support enables USB devices such as keyboards, mice, and hubs to be used even when the operating system’s USB drivers are not yet available. Legacy USB support is used to access the BIOS Setup program, and to install an operating system that supports USB.
Page 105: Bios Updates
During POST, an Intel splash screen is displayed by default. This splash screen can be replaced with a custom splash screen. A utility is available from Intel to assist with creating a custom splash screen. The custom splash screen can be programmed into the flash memory using the BIOS upgrade utility.
Page 106: Recovering Bios Data
To create a BIOS recovery diskette, a bootable diskette must be created and the BIOS update files copied to it. BIOS upgrades and the Intel Flash Memory Upgrade utility are available from Intel Customer Support through the Intel World Wide Web site.
