BIOS SETUP

•

SDRAM RAS-to-CAS Delay

This controls the latency between SDRAM active command and the read/write command.

Leave on default setting.

•

SDRAM RAS Precharge Time

This controls the idle clocks after issuing a precharge command to SDRAM. Leave on de-

fault setting.

•

SDRAM CAS Latency Time

This controls the SDRAM performance, default is 3 clocks. If your SDRAM DIMM specifica-

tion is 2 CAS latency, change 3 to 2 for better performance.

•

SDRAM Precharge Control

This option is to determine the number of clocks required to deassert RAS and the timing for

SDRAM to do precharge before next RAS can be issued.

•

DRAM Data Integrity Mode

NON-ECC : Disable Error Correct Check function.

ECC : Enable Error Correct Check Function.

•

System BIOS Cacheable

Selecting “Enabled” allows caching of the system BIOS. This action can increase system

performance.

•

Video BIOS Cacheable

Selecting “Enabled” allows caching of the video BIOS. This action can increase system per-

formance.

•

Video RAM Cacheable

Selecting “Enabled” allows caching of the video RAM, which results in better system perfor-

mance. However, if any program writes to this memory area, a system error may occur.

•

8 Bit I/O Recovery Time

Recovery time is needed for old 8-bit ISA cards. Default setting is 1 ISA clock. If you find any

unstable 8-bit ISA card, you may try to extend the I/O recovery time.

•

16 Bit I/O Recovery Time

Recovery time is needed for 16-bit ISA cards. Default setting is 1 ISA clock. If you find any

unstable 16-bit ISA cards, you may try to extend the I/O recovery time.
