BIOS Setup
Primary Master PIO to Secondary Slave 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 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.
