On-Chip Primary PCI IDE/On-Chip Secondary PCI IDE
These two options (option 1 and option 6) allows you to enable or disable the
onboard IDE Interface.

Primary/Secondary, Master/Slave PIO

The four IDE PIO (Programmed Input/Output) fields let you set a PIO mode
(0-4) for each of the four IDE devices that the onboard IDE interface supports.
Modes 0 through 4 provide successively increased performance. In Auto mode,
the system automatically determines the best mode for each device.
