PIO Mode
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 AMI
BIOS to auto detect the PIO mode. Use this value if the IDE disk drive support
cannot be determined. Select 0 to allow AMI BIOS to use PIO mode 0. It has a
data transfer rate of 3.3 MBs. Select 1 to allow AMI BIOS to use PIO mode 1. It
has a data transfer rate of 5.2 MBs. Select 2 to allow AMI BIOS to use PIO mode
2. It has a data transfer rate of 8.3 MBs. Select 3 to allow AMI BIOS to use PIO
mode 3. It has a data transfer rate of 11.1 MBs. Select 4 to allow AMI BIOS to
use PIO mode 4. It has a data transfer rate of 16.6 MBs. This setting generally
works with all hard disk drives manufactured after 1999. For other disk drives,
such as IDE CD-ROM drives, check the specifi cations of the drive.

disk. The options are Disabled, Enabled, and Auto.
32-Bit Data Transfer
Select "Enabled" to activate the function of 32-Bit data transfer. Select "Disabled"
to deactivate the function. The options are Enabled and Disabled.
