16-bit I/O Recovery Time
Common Options : NA, 4, 1, 2, 3
Quick Review
This BIOS feature allows you to add extra wait cycles between consecutive 16-bit PCI cycles to the ISA bus. This is used to correct timing issues between the PCI bus and ISA bus.
Please note that there is already a fixed minimum delay of 3.5 clock cycles so whatever you set using this BIOS feature adds to that delay. Choosing NA sets the number of delay cycles to the minimum 3.5 clock cycles.
Most 16-bit ISA cards will work fine with the minimum 3.5 delay cycles (NA). However, if your ISA card cannot work properly, try increasing the number of additional delay cycles.
