4.5.4.1 OnChip Primary/Secondary PCI IDE
The integrated peripheral controller contains an IDE interface with support for two
IDE channels. Select Enabled to activate each channel separately.
4.5.4.2 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.
4.5.4.3 IDE Primary/Secondary Master/Slave UDMA
These fields allow your system to improve disk I/O throughput to 33Mb/sec with the
Ultra DMA/33 feature. The options are Auto and Disabled.
