drives. These drives have a master/slave relationship which is
determined by the cabling configuration used to attach them
to the controller.
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. This is simpler and more
efficient.
Your system supports five modes, numbered from 0 to 4,
which primarily differ in timing. When Auto(default) is
selected, the BIOS will select the best available mode. This is
true for the next four setup items:
1. IDE Primary Master PIO
2. IDE Primary Slave PIO
3. IDE Secondary Master PIO
4. IDE Secondary Slave PIO
