Enabled Video BIOS access cached
Disabled Video BIOS access not cached
Video RAM Cacheable:
Select Enabled allows caching of the video RAM , resulting in
better system performance. However, if any program writes to this
memory area, a system error may result.
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 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. The available
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. The available 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.
Enabled
Memory hole supported
Disabled Memory hole not supported
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 available choices are Enabled,
Disabled.
Delayed Transaction:
The chipset has an embedded 32-bit posted write buffer to
support delay transactions cycles. Select Enabled to support
compliance with PCI specification version 2.1. The available
choices are Enabled, Disabled.
AGP Aperture Size (MB):
Select the size of the Accelerated Graphics Port (AGP) aperture.
The aperture is a portion of the PCI memory address range
dedicated for graphics memory address space. Host cycles that
hit the aperture range are forwarded to the AGP without any
translation. See www.agpforum.org for APG information. The
available choices are 16 MB, 32 MB, 64 MB, 128 MB, and 256MB.
