separately. This setup item allows you to determine the timing of the
transition from RAS (row address strobe) to CAS (column address strobe).
The less the clock cycles, the faster the DRAM performance. Setting
options: 3, 2.
DRAM RAS# Precharge
This item controls the number of cycles for Row Address Strobe (RAS)
to be allowed to precharge. If insufficient time is allowed for the RAS to
accumulate its charge before DRAM refresh, refresh may be incomplete
and DRAM may fail to retain data. This item applies only when synchro-
nous DRAM is installed in the system. Setting options: 2, 3.
DRAM Data Integrity Mode
Select ECC (Error-Checking & Correcting Code) or Non-ECC according to
the type of DRAM installed.
Memory Frequency For
Use this item to configure the clock frequency of the installed SDRAM. Set-
ting options: Auto, PC100, PC133.
DRAM Read Thermal Mgmt
This setting is used to activate the thermal management mechanism for DRAM
read actions. Setting options: Enabled, Disabled.
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. Setting options: Enabled,
Disabled.
Video BIOS Cacheable
Selecting Enabled allows caching of the video BIOS ROM at C0000h to
C7FFFh, resulting in better video performance. However, if any program writes
to this memory area, a system error may result. Setting options: Disabled,
Enabled.
Memory Hole At 15M-16M
In order to improve performance, certain space in memory can be reserved
for ISA cards. This memory must be mapped into the memory space below
