BIOS SETUP

System Memory Frequency

This field sets the frequency of the DRAM memory installed. The default setting is Auto. The other settings are DDR266, DDR333, DDR320 and DDR400.

System BIOS Cacheable

The setting of Enabled allows caching of the system BIOS ROM at F000h-FFFFFh, resulting in better system performance. However, if any program writes to this memory area, a system error may result.

Video BIOS Cacheable

The Setting Enabled allows caching of the video BIOS ROM at C0000h-F7FFFh, resulting in better video performance. However, if any program writes to this memory area, a system error may result.

Memory Hole At 15M-16M

In order to improve performance, certain space in memory can be reserved for ISA cards. This memory must be

On-Chip Frame Buffer Size Memory

Allow user to select the amount of system memory pre-allocated by the internal graphics device.

Fixed Memory Size

Specify the size of system memory to allocate for video memory.

DVMT Memory Size

Specify the size of DVMT memory to allocate for video memory.
