C. OnChip USB
Enable the on-board Universal Serial Bus (USB) controller if you want to connect
a USB keyboard to your system. Note that if this setting is disabled, you can
still temporarily use a USB keyboard during bootup so that you can enter BIOS
and enable this setting. If you pass the bootup stage without enabling this
function, your PS/2 keyboard will no longer work.
D. USB Keyboard Support
Select Enabled if your system has a USB keyboard installed on the system board.
If your system has no USB keyboard, select Disabled in this field.
E. IDE HDD Block Mode
Block mode is also called block transfer, multiple commands, or multiple sector
read/write. If your IDE hard drive supports block mode (most new drives do), select
Enabled for automatic detection of the optimal number of block read/writes per
sector the drive can support.
F. Onboard FDD Controller
Select Enabled if your system has a floppy disk controller (FDC) installed on the
system board and you wish to use it. If you install an add-in FDC or the system
has no floppy drive, select Disabled in this field.

This function allows you to select an operating mode for the second serial port.
( Normal RS-232C serial port /IrDA SIR 1.0 specification/ ASKIR 0.57-MB/sec

H. Onboard Parallel Port
Select a logical LPT port address and corresponding interrupt for the physical
parallel port.
I. Parallel Port Mode
Select an operating mode for the onboard parallel (printer) port. Select
SPP unless you are certain your hardware and software support one of the other
available modes.
