ON-CHIP PRIMARY PCI IDE
ON-CHIP SECONDARY PCI IDE:
The Integrated peripheral controller contains an IDE interface with support for
two IDE channels. Select Enabled to activate each channel separately.
IDE PRIMARY MASTER/SLAVE PIO:
IDE SECONDARY MASTER/SLAVE PIO:
The four IDE PIO fields allow you to 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.
IDE PRIMARY MASTER/SLAVE UDMA:
IDE SECONDARY MASTER/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. The implementation of UDMA is possible
only if your IDE hard drive supports it and the operating environ-ment
includes a DMA driver (Windows 95 OSR2 or a third-party IDE bus master
driver). If you hard drive and your system software both support Ultra
DMA/33, select Auto to enable BIOS support.
