BIOS Setup Power Management Features MSI Reminds You... S3-related functions described in this section are available only when your BIOS supports S3 sleep mode. Sleep 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. 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 in formation of system configuration and open applications/ files is saved to main memory that remains powered while most other hard- ware components turn off to save energy. The information stored in memory will be used to restore the system when a "wake up" event occurs. [Auto] BIOS determines the best mode automatically. Call VGA BIOS at S3 Resuming Selecting [Enabled] allows BIOS to call VGA BIOS to initialize the VGA card when system wakes up (resumes) from S3 sleep state. The system resume time is shortened 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 initialization feature, the display may work abnormally or not function after resuming from S3. 3-11

BIOS Setup
Power Management Features
Sleep 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. 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 in formation
of system configuration and open applications/ files is saved
to main memory that remains powered while most other hard-
ware components turn off to save energy. The information
stored in memory will be used to restore the system when a
“wake up” event occurs.
[Auto]
BIOS determines the best mode automatically.
Call VGA BIOS at S3 Resuming
Selecting [Enabled] allows BIOS to call VGA BIOS 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.
MSI Reminds You...
S3-related functions described in this section are available
only when your BIOS supports S3 sleep mode.
