Too many zeros?

And a few comments:
I presume that the default variable is single.  If not, you should see
errors.

Unless the machine is REALLY old, all of the bios you will get is the
part that finally gets loaded at &hF000.

Bioses generally only occupy the &hF000 segment.  Though, I have seen
machines where &hE000 was a dup of &hF000.
