SDRAM 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 data. Fast gives faster performance; and Slow gives more stable
performance. This field applies only when synchronous DRAM is installed in the system.
The Choice: 2, 3.
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 choice: Enabled, 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.
