Video BIOS Cacheable
Select Enabled allows caching of the system BIOS ROM at C0000h-
F7FFFh, resulting in better video performance. However, if any program
writes to this memory area, a system error may result.
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. 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.
Enabled
Memory hole supported.
Disabled
Memory hole not supported.
