System BIOS Cacheable [Default: Enabled]
Selecting Enabled allows caching of the system BIOS ROM at F0000h-FFFFFh, resulting
in better system performance. However, if any program writes to this memory area, a
system error may result.
Video BIOS Cacheable [Default: Disabled]
Selecting Enabled allows caching of the video BIOS ROM at F0000h-FFFFFh, resulting in
better video performance. However, if any program writes to this memory area, a
system error may result.
Memory Hole At 15M-16M [Default: Disabled]
Enable this function to allow ISA ROM to map to 15-16M and support Legacy ISA
devices. If you don’t utilize legacy ISA devices in your system, you are recommended to
disable this function to enhance graphic performance.
AGP Aperture Size (MB) [Default: 64]
Aperture size will ensure that all writes posted in the global write buffer to the graphics
aperture are retired to DRAM before initiating any CPU-PCI cycle. This can be used to
ensure synchronization between the CPU and AGP master.
** VGA Setting **
On-Chip VGA [Default: Enabled]
Enable/Disable the on-chip VGA.
On-Chip Frame Buffer Size [Default: 32M]
Determine video frame buffer size.
