OnChip IDE Channel0/1
The chipset contains a PCI IDE interface which supports two IDE channels. Select
“Enabled” to activate the first and/or second IDE interface. Select “Disabled” to deactivate
this interface if you install a primary and/or secondary add-in IDE interface.
•••••
IDE Prefetch Mode
The Onboard IDE drive interface supports IDE prefetching for faster drive access. If
your IDE drive has an add-in IDE interface and doesn’t support prefetching, please set
this field to “Disabled”.
•••••
Primary/Secondary Master/Slave PIO
The four IDE PIO (Programmed Input/Output) fields let you 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.
•••••
Primary/Secondary Master/Slave UDMA
Ultra DMA33/66/100 implementation is possible only if your IDE hard disk drive (HDD)
can support it and the operating environment includes a DMA driver (Windows 95 OSR2
or a third-party IDE bus master driver). If both your HDD and your system software can
support Ultra DMA33/66/100, select “Auto” to enable BIOS support.
