Tell you what, instead of us trying to guess what the options are on the main bios screen, why don't you tell us what options you've got.

And tell us whether you've got the AMI bios or the Award Bios, it say which on the bios screen.

Looks like the only bios updates are Award bios, you can update AMI bios to Award bios, using the AWD Flash utility.

The latest bios, flash utility and documentation are available here.

Edit: Can't see any useful features in the bios updates, but it may be useful to update to Award if you've got AMI bios.
