□ On-Chip Primary PCI IDE
□ On-Chip Secondary PCI IDE
The chipset contains a PCI IDE interface with support for two IDE channels. Select
Enabled to activate the IDE interface. Select Disabled to deactivate this interface, if
you install a primary and/or secondary add-in IDE interface.
□ IDE Primary Master PIO
□ IDE Primary Slave PIO
□ Secondary Master PIO
□ Secondary Slave PIO
The four IDE PIO (Programmed Input/Output) fields let you set a PIOmode (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.
□ IDE Primary Master UDMA
□ IDE Primary Slave UDMA
□ IDE Secondary Master UDMA
□ IDE Secondary Slave UDMA
UDMA (Ultra DMA) is a DMA data transfer protocol that utilizes ATA commands and
the ATA bus to allow DMA commands to transfer data at a maximum burst rate of 33
MB/s. When you select Auto in the four IDE UDMA fields (for each of up to four IDE
devices that the internal PCI IDE interface supports), the system automatically
determines the optimal data transfer rate for each IDE device.
