It seems you need to enter a password before you can edit the BIOS settings. I recommend looking through the manual for your chipset for a default password or, if the pc isn't yours contact your admin.

If none of those options work. There is a method of removing the BIOS battery (it should look like a watch battery) for a minute or 2. Then plug it back in and try to access the BIOS again; the password requirement should be gone. But don't do this without first looking a guide for you specific chipset.

See the article How to Bypass or Remove a BIOS Password

It describes 3 methods:

  1. Removing the CMOS Battery
  2. Using the !BIOS freeware utility
  3. Using the manufacturer backdoor password
