Integrated Peripherals
On-Chip Primary/Secondary PCI IDE
You can select to enable the primary IDE channel, secondary IDE channel, both, or disable
both channels.
Primary Master/Slave PIO/UDMA Mode, Secondary Master/Slave PIO/UDMA Mode
Each channel (0 & 1) has both a master and a slave making four IDE devices possible.
Because each IDE device may have a different PIO Mode timing of 0, 1, 2, 3, or 4, it is
necessary for these to be independent. DMA Mode timing allows 0, 1, or 2. The default
setting of Auto will allow auto-detection to ensure optimal performance.
IDE Prefetch Mode
The onboard IDE drive interfaces supports IDE prefetching for faster drive accesses. If you
install a primary and / or second IDE interface. Select Disabled to deactivate an interface, if
you install a primary and / or secondary add-in IDE interface.
