PIO
PIO means Programmed Input/Output. Rather 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
themselves. Your system suppor ts 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 accord-
ing to your hard disk drive’s timing.
Mode 0-4
You can select a mode that matches your hard disk
drive’s timing. Caution: Do not use the wrong
setting or you will have drive errors.
