Graphics Aperture Size This parameter determines the effective size of the graphics aperture. Graphics aperture is the address range that the AGP video and the CPU use to manage graphical objects. The lowest setting is 8 MB and the highest is 256 MB. Plug and Play OS When this parameter is set to Yes, BIOS initializes only PnP boot devices such as SCSI cards. When set to No, BIOS initializes all PnP boot and non-boot devices such as sound cards. The default setting for most operating systems is No. Reset Resource Assignments Set this parameter to Yes to avoid IRQ conflict when installing non-PnP or PnP ISA cards. This clears all resource assignments and allows BIOS to reassign resources to all installed PnP devices the next time the system boots. After clearing the resource data, the parameter resets to No. Chapter 2 - BIOS Utility 2-33

Graphics Aperture Size
This parameter determines the effective size of the graphics aperture.
Graphics
aperture is the address range that the AGP video and the CPU use to manage
graphical objects.
The lowest setting is 8 MB and the highest is 256 MB.
Plug and Play OS
When this parameter is set to
Yes
, BIOS initializes only PnP boot devices such as
SCSI cards.
When set to
No
, BIOS initializes all PnP boot and non-boot devices
such as sound cards.
The default setting for most operating systems is
No
.
Reset Resource Assignments
Set this parameter to
Yes
to avoid IRQ conflict when installing non-PnP or PnP ISA
cards.
This clears all resource assignments and allows BIOS to reassign resources
to all installed PnP devices the next time the system boots.
After clearing the
resource data, the parameter resets to
No
.
