BIOS Setup
3.1.4 Integrated Peripherals
The settings on the screen are for reference only. Your version may not be identical
to this one.
3.1.4.1 On-Chip Primary PCI IDE and On-Chip Secondary PCI IDE
These fields allow you to enable or disable the primary and sec-
ondary IDE controller. Select Disabled if you want to add a differ-
ent hard drive controller.
3.1.4.2 IDE Primary Master/Slave PIO and IDE Secondary Master/
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 com-
plete task by themselves. Your system supports five modes, 0 (de-
fault) to 4, which primarily differ in timing. When Auto is selected,
the BIOS will select the best available mode after checking your
drive.
