AWARD BIOS SETUP
4-10
Video BIOS Cacheable:

Selecting
Enabled
allows caching of the video BIOS ROM at C0000h to C7FFFh,
resulting in better video performance.
Enabled
Video BIOS /RAM access cached
Disabled
Video BIOS /RAM access not cached
Memory Hole At 15M-16M:
( default setting : “Disabled” )
In order to improve performance, certain space in memory can be reserved for ISA
cards. Such memory must be mapped into the memory space below 16 MB.
Enabled
Memory hole supported.
Disabled
Memory hole not supported.
CPU Latency Timer
( default setting : “Disabled” )
This field allows you to configure GMCH’s response to CPU deferrable cycle
Delayed Transaction

transactions cycles. Select Enabled to support compliance with PCI specification
version 2.1..
The Choice: Enabled, Disabled.
On-Chip Video Window Size : (
default setting: 64MB )
This mainboard provides the most DVMT technology (Dynamic Video Memory
Technology) and it will increase the video display performance. There is the AGP
VGA interface on this mainboard and the AGP display card will use some of the
system memory to store 3D texture mapping data to increase the video display
performance. You may use this field to define the memory size which you prefer to
use for the AGP card. The memory size selectable in this field can be "Disable" or
32MB or 64MB DVMT. When you select 64MB DVMT, it does not mean that the
PC system will use that much memory. Then memory size defined in this field will
be the maximum memory which Windows 95/98 can use to story the 3D texture.
When you select the 64MB DVMT, you will see 1024K memory is allocated as the
share memory when you power on the PC system. When you start the Windows
operation system, Windows will allocate the required display share memory
dynamically.
