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. Available options are [Enabled] and [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. Available options are [Auto], [Mode 0], [Mode

1], [Mode 2], [Mode 3], [Mode 4].

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, 66 and

100, select Auto to enable BIOS support. Available options are [Auto]

and [Disabled].

controller and you have USB peripherals. Available options are

[Enabled]and [Disabled].

Select [Enabled] if your system contains a Universal Serial Bus (USB)

controller and you have a USB keyboard. Available options are [Enabled]

and [Disabled].

display. Available options are [PCI slot] and [AGP].
