Advanced Configuration and Power Interface (ACPI) ACPI gives the operating system direct control over the power management and Plug and Play functions of a computer. ACPI requires an ACPI-aware operating system. ACPI features include: • Plug and Play (including bus and device enumeration) and APM functionality normally contained in the BIOS. • Power management control of individual devices, add-in boards, video displays, and hard disk drives. • Methods for achieving less than 30-watt system operation in the Power On Suspended sleeping state, and less than 5-watt system operation in the Suspended to Disk sleeping state. • A soft-off feature that enables the operating system to power off the computer. • Support for multiple wake up events. • Support for a front panel power and sleep mode switch. Table 19 describes the system states based on how long the power switch is pressed, depending on how ACPI is configured with an ACPI-aware operating system. Table 19: Effects of Pressing the Power Switch If the system is in this ... and the power switch is state... pressed for Off Less than 4 seconds On Less than 4 seconds On More than 4 seconds Sleep Less than 4 seconds ...the system enters this state Power On Soft Off/ Suspended Fail safe power off Wake up Under ACPI, the operating system directs all system and device power state transitions. The operating system puts devices in and out of low-power state based on user preferences and knowledge of how devices are being used by applications. Devices that are not being used can be turned off. See Power Management section in Chapter 1, Page 28 for more information on ACPI. Language Support The Setup program and help messages can be supported in 32 languages. The default language is American English, which is present unless another language is programmed into the BIOS using the flash memory update utility. Boot Options In the Setup program, the user can choose to boot from a floppy drive, hard drive, CD-ROM, or the network. The default setting is for the floppy drive to be the primary boot device and the hard drive to be the secondary boot device. By default the third and fourth devices are disabled. Booting from CD-ROM is supported in compliance to the El Torito bootable CD-ROM format specification. Under the Boot menu in the Setup program, CD-ROM is listed D865GLC Motherboard Manual 56

Advanced Configuration and Power Interface (ACPI)
ACPI gives the operating system direct control over the power management and
Plug and Play functions of a computer. ACPI requires an ACPI-aware operating
system. ACPI features include:
•
Plug and Play (including bus and device enumeration) and APM
functionality normally contained in the BIOS.
•
Power management control of individual devices, add-in boards, video
displays, and hard disk drives.
•
Methods for achieving less than 30-watt system operation in the Power On
Suspended sleeping state, and less than 5-watt system operation in the
Suspended to Disk sleeping state.
•
A soft-off feature that enables the operating system to power off the
computer.
•
Support for multiple wake up events.
•
Support for a front panel power and sleep mode switch. Table 19 describes
the system states based on how long the power switch is pressed,
depending on how ACPI is configured with an ACPI-aware operating
system.

Under ACPI, the operating system directs all system and device power state
transitions. The operating system puts devices in and out of low-power state based
on user preferences and knowledge of how devices are being used by applications.
Devices that are not being used can be turned off.
See Power Management section
in Chapter 1, Page 28 for more information on ACPI.
Language Support
The Setup program and help messages can be supported in 32 languages. The
default language is American English, which is present unless another language is
programmed into the BIOS using the flash memory update utility.
Boot Options
In the Setup program, the user can choose to boot from a floppy drive, hard drive,
CD-ROM, or the network.
The default setting is for the floppy drive to be the primary
boot device and the hard drive to be the secondary boot device.
By default the third
and fourth devices are disabled.
Booting from CD-ROM is supported in compliance to the El Torito bootable CD-ROM
format specification.
