Video BIOS Cacheable

Selecting “Enabled” allows caching of the video BIOS. This action can increase system

performance.

Memory Hole at 15M-16M

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 Latency Timer

The option determines the way that 815 uses the deferrable processor cycle.

Delayed Transaction

PCI access speed is faster than ISA. So PCI will release the master bus to the ISA interface

for accessing data. Then the master bus control will go back to PCI again.

AGP Graphics Aperture Size

The Aperture is a portion of the PCI memory address range dedicated for graphics memory

address space. Access to the aperture range is forwarded to AGP without any translation.

Available options are 64MB and 32MB.

System Memory Frequency

Default is “Auto”. When the CPU is 133MHz you can choose 100/133MHz, but when the

CPU is 100MHz, only the 100MHz selection functions.

On-Chip Video Window Size

You can select the size of mapped memory for the VGA/AGP driver to use. The choices are:

“64MB”, “32MB”, and “Disabled”.
