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 location 15-16MB.
