And/or had the ability to gain such, as for what the Power Users group in
Win2K+ is.

Okay, but I was assuming it was a typical windows user who ran everything
from an account with admin rights.

Which minds another question: What about malware hosing the BIOS?

No need to speculate - the Chernobyl virus would indeed trash some BIOSes.

I rather thought about constructively hosing the BIOS by adding a rootkit,
f.e. as presented on DevCon '06. This is really to miracle, since a typical
Award or AMI BIOS consists primarly of a little bootstrap code, a
decompressor and a list of LHARC or ZIP compressed BLOBs of
position-independent code. Just write your own code, compress it, add it to
the list and write back the result. The typically free space ranges from 6K
to 48K, that's more than enough to complete hook the entire boot process of
Windows. On AMD CPUs, you can even introduce your very own microcode update
pretty easily.
