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. 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 98SE/ 2000/ME/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. 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 components turn off to save energy. The information stored in memory will be used to restore the system when a "wake up" event occurs. Re-Call VGA BIOS from S3 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. 3-17

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.
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 98SE/
2000/ME/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. 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.
Re-Call VGA BIOS from S3
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.
