System BIOS
Select Enabled allows caching of the system BIOS ROM at
Cacheable
F0000h-FFFFFh, resulting in better system performance.
However, if any program writes to this memory area, a system
error may result.
Video BIOS
Select Enabled allows caching of the video BIOS ROM at
Cacheable
F0000h-FFFFFh, resulting in better system performance.
However, if any program writes to this memory area, a system
error may result.
Video RAM
Select Enabled allows caching of the video RAM, resulting in
Cacheable
better system performance. However, if any program writes to
this memory area, a system error may result.
8 Bit I/O
The recovery time is the length of time, measured in CPU
Recovery Time
clocks, which the system will be delay after the completion of
an I/O request. This delay takes place because the CPU is
operating so much faster 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
This item allows you to determine the recovery
Recovery Time
time allowed for 16-bit I/O. Choices are from NA,
1 to 4 CPU clocks.
Memory Hole At
In order to improve performance, certain space
15M-16M
in memory can be reserved for ISA cards. This memory
must be mapped into the memory below 16MB.
Passive Release
When Enabled, CPU to PCI bus accesses are allowed during
passive release. Otherwise, the arbiter only accepts another PCI
master access to local DRAM.
The choice : Enabled, disabled
Delayed
This chipset has an embedded 32-bit posted write buffer to
Transaction
support delay transactions cycles. Select Enabled to support
compliance with PCI specification version 2.1.
The choice : Enabled, disabled space
