Award BIOS Utility

The Phoenix-Award BIOS provides users with a built-in Setup program to modify basic system configuration. All configured parameters are stored in a battery-backed-up RAM (CMOS RAM) to save the Setup information whenever the power is turned off.

There are two ways to enter the Setup program. You may either turn

ON the computer and press <Del> immediately, or press the <Del> and/or <Ctrl>, <Alt>, and <Esc> keys simultaneously when the following message appears at the bottom of the screen during POST

(Power on Self Test).

TO ENTER SETUP PRESS DEL KEY

If the message disappears before you respond and you still want to enter Setup, please restart the system to try it again. Turning the system power OFF and ON, pressing the “RESET” button on the system case or simultaneously pressing <Ctrl>, <Alt>, and <Del> keys can restart the system. If you do not press keys at the right time and the system doesn’t boot, an error message will pop out to prompt you the following information:

This item specifies the power saving modes for ACPI function. If your operating system supports ACPI, such as Windows 98SE,

Windows ME and Windows 2000, you can choose to enter the

Standby mode in S1 (POS) or S3 (STR) fashion through the setting of this field. Options are:

[S1 (POS)] The S1 sleep mode is a low power state. In this state, no system context is lost (CPU or chipset) and hardware maintains all system contexts.

[S3 (STR)] The S3 sleep mode is a lower power state where the information of system configuration and open applications/files is saved to main memory that remains powered while most other hardware components turn off to save energy. The information stored in memory will be used to restore the system when a “wake up” event occurs. z

Power Management

This option allows you to select the type (or degree) of power saving for Doze, Standby, and Suspend modes. The table below describes each power management mode:

Max Saving

User Define

Min Saving

The inactivity period is 1 minute in each mode.

It sets each mode. Select time-out periods in the PM

Timers section.

It is minimum power savings. The inactivity period is 1 hour in each mode (except the hard drive).

Default value z PM Control by APM

If Advanced Power Management (APM) is installed in your system, the selection of Yes will give better power savings. The default value is “Yes”.

No

Yes

System BIOS will ignore APM when power is managing the system

The System BIOS will wait for APM’s prompt before it enters any PM mode (i.e., DOZE, STANDBY or SUSPEND).

Note: If APM is installed or there is a task running, even when the timer has timed out, the APM will not prompt the BIOS to put the system into any power saving mode

!

NOTE: If APM is not installed, this option doesn’t work.
