DRAM Idle Timer

This item specifies the number of clocks that the DRAM controller will remain in IDLE
state before precharging all pages.

SDRAM CAS Latency Time

This item defines the CAS Latency timing parameter of the SDRAM expressed in 66MHz
clocks.  The options are 2 and 3 CLKs.

SDRAM Precharge Control

This item Enable/Disable the SDRAM precharge when a page miss occurs.

DRAM Data Integrity Mode

This item allows the user to set DRAM data integrity mode to

 

Non-ECC

 or 

ECC

.  Non-

ECC has byte-wide write capability but no provision for protecting data integrity in the
DRAM array. ECC allows a detection of single-bit and multiple-bit errors and recovery of
single-bit errors.

System BIOS Cacheable

This item allows the user to set whether the system BIOS F000~FFFF areas are cacheable
or non-cacheable.

Video BIOS Cacheable

This item allows the user to set whether the video BIOS C000~C7FF areas are cacheable
or non-cacheable.

Video RAM Cacheable

This is a new cache technology for the video memory of the processor.  It can greatly
improve the display speed by caching the display data.  You must leave this on the default
setting of 

Disabled

 if your display card cannot support this feature or else your system

may not boot.

8 Bit I/O Recovery Time

The recovery time is the length of time, measured in CPU clocks, which the system will
delay after the completion of an input/output request.  This delay takes place because the
CPU is operating so much after than the input/output bus that the CPU must be delayed to
allow for the completion of the I/O.

This item allows you to determine the recovery time allowed for 8 bit I/O. Choices are
from NA, 1 to 8 CPU clocks.

16-Bit I/O Recovery Time

This item allows you to determine the recovery time allowed for 16 bit I/O.  Choices are
from NA, 1 to 4 CPU clocks.

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 16 MB.
