OnChip Primary/Secondary PCI IDE
The integrated peripheral controller contains an IDE interface with support for two
IDE channels. Select Enabled to activate each channel separately.
The choice: Enabled, Disabled.
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 choice: Auto, Mode 0, Mode 1, Mode 2, Mode 3, Mode 4.
IDE Primary/Secondary Master/Slave UDMA
Ultra DMA/33 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 sup-
port Ultra DMA/33, select Auto to enable BIOS support.
The Choice: Auto, Disabled.
