System BIOS Cacheable
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. The settings are: Enabled and Disabled.
Video BIOS Cacheable
Select Enabled allows caching of the video BIOS, resulting in better system performance.
However, if any program writes to this memory area, a system error may result. The settings
are: Enabled and Disabled.

DRAM CAS Latency
When synchronous DRAM is installed, the number of clock cycles of CAS latency depends
on the DRAM timing. The settings are: 2T, 2.5T and 3T.
RAS Precharge Time
If an insufficient number of cycles is allowed for the RAS to accumulate its charge before
DRAM refresh, the refresh may be incomplete and the DRAM may fail to retain date. Fast
gives faster performance; and Slow gives more stable performance. This field applies only
when synchronous DRAM is installed in the system. The settings are: 2T and 3T.
RAS-to-CAS Delay
This field let’s you insert a timing delay between the CAS and RAS strobe signals, used when
DRAM is written to, read from, or refreshed.
Fast
gives faster performance; and
Slow
gives
more stable performance. This field applies only when synchronous DRAM is installed in
the system. The settings are: 2T and 3T.
