Appendix
Video
Primary Video
( Auto default)
This setting specifies which video controller is primary when there is two video
controllers availble (
PCI , Onboard , Auto , and PEG ). This selection only matters when
if there are two video controllers present. When Auto is selected, the add-in video
controller will be used.
NOTE:
A PCI Express graphics card will override the integrated video controller.
Video Memory Size
( 64MB default)
This setting configures the amount of system memory that is reserved for the
integrated video controller. The settings are Auto, 16MB, 32MB, 64MB, 128MB, or
Off.

• Bypass — Your computer does not test or change the current acoustics mode setting.
• Quiet — The hard drive operates at its most quiet setting.
• Suggested — The hard drive operates at the level suggested by the drive manufacturer.
• Performance — The hard drive operates at its maximum speed.

Switching to performance mode may cause the drive to be noisier, but its

image.
