Slave Drive Ultra DMA:
"
Auto: When you select Auto, the system automatically determines
the optimal data transfer rate for each IDE device. (Default)
"
Disabled: If you encounter the problem of using Ultra DMA devices,
you can try to Disable this item.
PIO MODE 0~4 reflects the IDE device data transfer rate. The higher the
MODE value is, the better is the IDE device data transfer rate. But it does not
mean that you can select the highest MODE value just as you like, you first
have to be sure that your IDE device supports this MODE, otherwise the hard
disk will not be able to operate normally.
USB Keyboard Support Via:
You can choose either the OS or the BIOS to support the USB keyboard.
Depending on the situation. Two options are available: OS or BIOS, OS is the
default setting. With the BIOS option, you can use a USB keyboard under the
MS-DOS environment but don’t need to install a driver.
Init Display First:
When you install more than one display cards, you can choose either a PCI
display card or an AGP display card to activate the display boot-up screen. If
you only installed one display card, the BIOS will detect which slot (AGP or
PCI) you installed it, in then everything will be take care of by the BIOS.

This item allows you to change the keyboard clock, if you have a keyboard
problem, like keyboard failure, slow typing response time, etc. You may try to
change the keyboard clock settings for optimal result.
