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 RAM 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.
Memory Hole
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 settings are: Enabled and Disabled.

RAS Active Time
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.
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.
