Video BIOS Cacheable

Selecting Enabled allows caching of the video BIOS
ROM at C0000h to CBFFFh, resulting in better
video performance. However, if any program writes
to this memory area, a system error may result.

Memory Hole At 15M-16M

You can reserve this area of system memory for ISA
adapter ROM. When this area is reserved, it
cannot be cached. The user information of
peripherals that need to use this area of system
memory usually discusses their memory
requirements.

The chipset has an embedded 32-bit posted write
buffer to support delay transactions cycles. Select

Select the interval to setup the delay timer for CPU
Thermal-Throttling.

(AGP) aperture. The aperture is a portion of the
PCI memory address range dedicated for graphics
memory address space. Host cycles that hit the
