BIOS Setup

Power Management Setup

ACPI Function

This item is to activate the ACPI (Advanced Configuration and Power Management

Interface) Function. If your operating system is ACPI-aware, such as Windows 2000/

XP, select [Enabled]. Setting options: [Enabled] and [Disabled].

ACPI Standby State

This item specifies the power saving modes for ACPI function. If your operating

system supports ACPI, such as Windows 98SE, Windows ME, Windows 2000 and

Windows XP, you can choose to enter the Standby mode in S1(POS) or S3(STR)

fashion through the setting of this field. Setting 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

context.

[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 compo

nents turn off to save energy. The information stored in memory will

be used to restore the system when a “wake up” event occurs.

[Auto] System auto arrange for ACPI function.

Re-Call VGA BIOS from S3

When ACPI Standby State is set to [S3/STR], users can select the options in this

field. Selecting [Yes] allows BIOS to call VGABIOS to initialize the VGA card when

system wakes up (resumes) from S3 sleep state. The system resume time is short-

ened when you disable the function, but system will need an AGP driver to initialize

the VGA card. Therefore, if the AGP driver of the card does not support the initializa-

tion feature, the display may work abnormally or not function after resuming from S3.

Options: [Auto], [Yes], [No].

MSI Reminds You...

S3-related functions described in this section are available only when

your BIOS supports S3 sleep mode.
