User`s manual

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.

Memory Hole At 15M-16M

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.

CAS # Latency

When synchronous DRAM is installed, the number of clock cycles of CAS latency depends

on the DRAM timing. The settings are: Auto,3, 4 and 5.

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: 4T 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.
