OnChip IDE First/Second Channel
The integrated peripheral controller contains an IDE interface with
support for two IDE channels. Select Enabled to activate each channel
separately.
IDE Prefetch Mode
This field allows your hard disk to prefetch the next read and initiate the
next process.
IDE HDD Block Mode
This field allows your hard disk controller to use the fast block mode to
transfer data to and from your hard disk drive.
IDE Primary/Secondary Master/Slave PIO
These fields allow your system hard disk controller to work faster. Rather
than have the BIOS issue a series of commands that transfer to or from
the disk drive, PIO (Programmed Input/Output) allows the BIOS to
communicate with the controller and CPU directly.
The system supports five modes, numbered from 0 (default) to 4, which
primarily differ in timing. When Auto is selected, the BIOS will select the
best available mode.
