EDO DRAM Read Burst
This item set the EDO DRAM Read Burst Timing. The timing used depends on the type
of DRAM (EDO burst mode or standard fast page mode) on a per-bank basis. The options
are
222 and 333 .
EDO DRAM Write Burst
This item set the EDO DRAM Write Burst timing for accessing DRAM. The options are
222 and 333 .
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.
CPU-To-PCI IDE Posting
When disabled, the CPU to PCI IDE posting cycles are treated as normal I/O write
transactions. When enabled will have the I/O write cycles posted.
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.
