On-Chip IDE Chanel 0/1: (Default setting: “Enabled” )
The integrated peripheral controller contains an IDE interface with support for two
IDE channels. Select Enabled to activate each channel separately
IDE Prefetch Mode: (Default setting: “Enabled” )
This allows you to select the IDE interface prefetch mode. Basically, Enable is
suggested because it will increase the HDD data performance.
Primary/Secondary Master/Slave PIO: (Default setting: “Auto” )
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.
