IDE HDD Block Mode
This allows your hard disk controller to use the fast block mode to transfer data to and from your hard disk
drive (HDD).
Enabled
IDE controller uses block mode.
Disabled IDE controller uses standard mode.
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.
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 support Ultra DMA/33, select Auto to enable BIOS support. The Choice: Auto, Disabled
On-Chip 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.
USB Keyboard support
Select Enabled if your system contains a Universal Serial Bus (USB) controller and you have a USB keyboard.
The Choice: Enabled, Disabled.
