IDE Primary/Secondary Master/Slave PIO
These fields allow your system hard disk controller to work faster. Rather
than have the BIOS issue a series of commands that transfer to or from
the disk drive, PIO (Programmed
Input/Output) allows the BIOS to
communicate with the controller and CPU directly.
The system supports five modes, numbered from 0 (default) to 4, which
primarily differ in timing. When Auto is selected, the BIOS will select the
best available mode.
IDE Primary/Secondary Master/Slave UDMA
