BIOS SETUP
•
Fast R-W Turn Around
DRAM optimization feature: If a memory read is addressed to a location whose latest write
is being held in a buffer before being written to memory, the read is satisfied through the
buffer contents, and the read is not sent to the DRAM.
The choices: “Enabled” and “Disabled”.

Frame Buffer Size
This item allows you to control the internal VGA frame buffer size (NA/4M/8M/16M/32M).
•
AGP Aperture Size (MB)
Memory-mapped graphics data structures can reside in a Graphic Aperture. We suggest
you leave this field on the default setting.
•
AGP- 4X Mode
Select “Enable” if you use a AGP-4X VGA card.
•
AGP Driving Control
This function allows you to adjust the AGP driving force. Choosing ‘Manual’ allows you key
in an AGP Driving Value in the next selection. We recommend that you set this field to “Auto”
to avoid any error in the system.
•
Memory Hole
Enabling this feature reserves memory address space (between 15 and 16MB) to ISA
expansion cards that specifically require this setting. This makes between 15 and 16MB of
memory unavailable to the system. Expansion cards can only access memory up to 16MB.
The default setting is “Disabled”.
•
CPU/PCI Concurrency
When “Disabled”, the CPU bus will be occupied during the entire PCI operation period.
•
AGP Driving Value
This field allows you to adjust the AGP driving force (from OO~FF).
