4.4.2 PCI and IDE Configuration
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.
