ACPI Function 
This function should be enabled only in operating systems that support ACPI. 
Currently, only Windows® 98SE/2000/ME/XP supports this function. When this 
field is enabled, the system will ignore the settings in the “Suspend Mode” and 
“HDD Power Down” fields. If you want to use the Suspend to RAM function, 
make sure this field is enabled then select“S3 (STR)” in the field below. 
․ACPI Suspend Type 
This field is used to select the type of Suspend mode. 
S1(POS) 
Enables the Power On Suspend function. 
S3(STR) 
Enables the Suspend to RAM function. 
S1 & S3 
If S3 state is supported by the system, by default [S3] is 
automatically selected. Otherwise [S1] is selected. 
․Run VGABIOS if S3 Resume 
Select whether to run VGA BIOS if resuming from S3 state. This is only 
necessary for older VGA drivers.
