Descriptions on each item above are as follows:
1. OnChip IDE Channel 0 / 1
The chipset contains a PCI IDE interface with support for two IDE
channels. Select Enabled to activate the secondary IDE interface.
Select Disabled to deactivate this interface.
2. IDE Prefetch Mode
The onboard IDE drive interfaces supports IDE pre-fetching for faster
drive accesses. If you install a primary and or secondary add-in IDE
interface, set this field to Disabled if the interface does not support pre-
fetching.
3. Primary Master/Slave PIO
Secondary Master/Slave PIO
The four IDE PIO fields allow you to 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.
