4.3.2.12System BIOS Cacheable
When this option is set to Enabled, the contents of the F0000h system memory segment can be read from or written to L2 cache memory. The contents of the F0000h memory segment are always copied from the BIOS ROM to system RAM for faster execution. The settings are Enabled or Disabled.
4.3.2.13Shadow Memory (from Address C000~DFFF, 16K Per Segment)
Each of segments provides three options “Disabled”, “Enabled”, and “Cached” for faster adapter’s ROM execution. However this shadow function is Chipset oriented and dependent on system hardware feature. In general, C000 and C800 will be allocated for VGA BIOS and set to Cached to get higher display performance by shadowing and caching feature. If user chooses Enabled setting, only BIOS shadow function is active.
