Chapter4 BIOS Setup
Fast R-W Turn Around This item controls the DRAM timing. It allows you to
enable / disable the fast read / write turn around.
The choices: Enabled; Disabled.
System BIOS selecting Enabled allows caching of the system BIOS
Cacheable ROM at F0000h-FFFFFh, resulting in better system
performance.
Video RAM Cacheable Selecting Enabled allows caching of the video memory
(RAM) at A0000h to AFFFFh, resulting in better video
performance.
However, check your AGP manual to find out if any
compatibility problem exists.
AGP Aperture Size Series of options are available: 4, 8, 16, 32, 64, 128
or 256 MB. Memory mapped and graphics data struc-
tures can reside in a Graphics Aperture. This area is
like a linear buffer. BIOS will automatically report the
starting address of this buffer to the O.S. The default
setting is 64MB.
AGP Driving Control This item allows you to adjust the AGP driving force.
Choose "Manual" to key in a AGP Driving Value in
the next selection. This field is recommended to set
to "Auto" for avoiding any error in your system.
The choices: Manual; Auto.
AGP Driving Value This item allows you to adjust the AGP driving force.
The choices: Min=0000 ~ Max=00FF.
AGP Fast Write This item will enable the AGP model into fast write
mode. If your graphics card does not support this
function, please do not enable this function.
OnChip USB/USB2 This should be enabled if our system has a USB in-
stalled on the system board and you wish to use it.
Even when so equipped, if you add a higher perfor-
mance controller, you will need to disable this feature.
The choices: Enabled; Disabled.
