PIO Mode
The IDE PIO (Programmable I/O) Mode programs timing cycles between the
IDE drive and the programmable IDE controller. As the PIO mode increases, the
cycle time decreases. The options are Auto, 0, 1, 2, 3, and 4.
Select Auto to allow the AMI BIOS to automatically detect the PIO mode. Use
this value if the IDE disk drive support cannot be determined.
Select 0 ~ 4 to allow the AMI BIOS to use PIO mode 0 ~ 4. It has a data transfer
rate of 3.3 MB/s ~ 16.6 MB/s. See the table below.
