Intel Desktop Board D815EFV/D815EPFV Technical Product Specification
1.15.1.2
48
The BIOS enables APM by default; but the operating system must support an APM driver for the
power management features to work. For example, Windows 98 supports the power management
features upon detecting that APM is enabled in the BIOS.
ACPI gives the operating system direct control over the power management and Plug and Play
functions of a computer. The use of ACPI with the D815EFV or D815EPFV board requires an
operating system that provides full ACPI support. ACPI features include:
•
•
•
•
•
•
Table 9.

Plug and Play (including bus and device enumeration) and APM support normally contained in
the BIOS.
Power management control of individual devices, add-in boards (some add-in boards may
require an ACPI-aware driver), video displays, and hard disk drives.
Methods for achieving less than 15-watt system operation in the power-on/standby sleeping
state.
A soft-off feature that enables the operating system to power-off the computer.
Support for multiple wake up events (see Table 11 on page 50).
Support for a front panel power and sleep mode switch. Table 9 lists the system states based
on how long the power switch is pressed, depending on how ACPI is configured with an
ACPI-aware operating system.
