IDE UDMA (Ultra DMA) Mode
-
The chipset used for this mainboard improves the
IDE performance by implementing UltraDMA/33 Bus Mastering IDE which can handle
data transfer up to 33 Mbyte/sec. This UDMA technology is downward compatible with
existing ATA-2 IDE. So there is no upgrade required for current hard drives and cabling.

Auto is
default.
USB Keyboard Support -
This item allows you to enable or disable the USB keyboard
driver within the onboard BIOS. The keyboard driver simulates legacy keyboard command
