anyhoo, go to www.abit.com.tw and download the manual for the BD7-ii. There you will see how the BIOS is set up for that particular board. Also entering 'Abit BD7II' into a google search gives you several reviews of this board...and I'm sure most of them will describe the various BIOS functions as well. After this bit of research your friend (and you as well) should have a much easier time of installing the mobo as you already sort of know what to expect.
I could have looked at the manual and reviews and told you the info, but this way you learn how to find out all you need to know on your own about any mobo very quickly.
