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

USB Controller

Select [Enabled] if your system contains a Universal Serial Bus (USB)
controller and you have USB peripherals. Available options are [Enabled]
and [Disabled].

USB Keyboard Support

Select [Enabled] if your system contains a Universal Serial Bus (USB)
controller and you have a USB keyboard. Available options are [Enabled]
and [Disabled].

Init Display First

device on the system. Thus the AGP display becomes the primary
display. Available options are [PCI slot] and [AGP].
