Description
Setting these items to Auto activates the HDD speed
auto-detect function. The PIO mode specifies the data
transfer rate of the HDD. For example, mode 0 data
transfer rate is 3.3 MB/s, mode 1 is 5.2 MB/s, mode 2 is
8.3 MB/s, mode 3 is 11.1 MB/s and mode 4 is 16.6 MB/s.
If your hard disk performance becomes unstable, you
may manually try the slower mode.
Caution: It is recommended that you connect the first
IDE device of each channel to the endmost
connector of the IDE cable.
These items allow you to set the Ultra DMA/33/66/100
mode supported by the hard disk drive connected to your
primary and secondary IDE connectors.
This item is used to enable or disable the On-chip USB.
This item lets you enable or disable the USB keyboard

simulates legacy keyboard command and lets you use a
USB keyboard during POST or after boot if you don't
have a USB driver in the operating system.
This item lets you enable or disable the USB mouse
driver within the onboard BIOS. The mouse driver
simulates legacy mouse command and lets you use a
USB mouse during POST or after boot if you don't have

If you installed a PCI VGA card and an AGP card at the
same time, this item lets you decide which one is the
initial display card.
This feature enhances disk performance by allowing
multisector data transfers and eliminates the interrupt
handling time for each sector. Most IDE drives, except
with old designs, can support this feature.

Any Key (press any key on the PS2 keyboard or press
the power button)

Setting this parameter to Enabled allows you to connect
your floppy disk drives to the onboard floppy disk
connector instead of a separate controller card. Change
the setting to Disabled if you want to use a separate
controller card.
This item allows you to assign an address and interrupt
for the board serial port.
