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.
