BIOS Setup
PIO Mode
Selects the data transfer mode. PIO means Programmed Input/Output. Rath-
er than have the BIOS issue a series of commands to effect a transfer to or
from the disk drive, PIO allows the BIOS to tell the controller what it wants
and then let the controller and the CPU perform the complete task by them-
selves. Your system supports five modes, 0 (default) to 4, which primarily
differ in timing. When Auto is selected, the BIOS will select the best available
mode after checking your drive.
Auto
The BIOS will automatically set the system according to your hard disk
drive’s timing.

Do not use the wrong setting or you will have drive errors.
