Both. Also I would personally flash the UnModified Version with the /pbnc /n switches first and use it for a few days to make sure that update works like it should on your PC, BEFORE you flash the Modded Bios.
Thank you again. I'm actually currently running the unmodified version of this Bios - I upgraded a while ago using windows Asus Update tool, and it seems to work correctly.
Just how bad would it be to try and update bios from Windows? I can't seem to boot into DOS no matter what I try.
