Maybe we could get setmax into extras. It seems like a tool people might
have use for.

I built it and used it read only and it seemed to work. I got some warnings
about exit because it is missing:
#include <stdlib.h>
But otherwise it compiled cleanly.
I didn't want to try set an HPA on any of my drives, to see if that worked.
I also tested in of FC5, not F7.

I didn't see a license on the page where it is distributed, so someone
would have to check with Brouwer or rewrite it.
