OnChip IDE Channel0/1
These fields enable or disable the first and second IDE channels on board.
Each channel supports two IDE devices.
IDE Prefetch Mode
These field enables/disables the prefetch buffers in the PCI IDE
controller. The prefetch buffers are used as a temporary storage place as
data is transferred from one location to another.
IDE Primary Master/Slave PIO, 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.
