Integrated Peripherals
On-Chip Primary/Secondary PCI IDE
The integrated peripheral controller contains an IDE interface with support
for two IDE channels. Choose Enabled to activate each channel separately.
IDE 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. The set-
tings are: Auto, Mode 0, Mode 1, Mode 2, Mode 3, Mode 4.
IDE Primary/Secondary Master/Slave UDMA
Ultra DMA/33/66/100 implementation is possible only if your IDE hard drive
supports it and the operating environment includes a DMA driver (Windows
95 OSR2 or a third-party IDE bus master driver). If your hard drive and your
system software both support Ultra DMA/33, Ultra DMA/66 or even Ultra
DMA/100, select Auto to enable BIOS support. Settings: Auto, Disabled.
