I cannot get a Soekris net5501 to boot OpenBSD 4.5 from a hard drive.
Much traffic has passed on the Soekris email list. I've now included
[email protected], because it might be an OpenBSD problem.
I re-installed OpenBSD. And I noticed a problem at the end of the
install process. I have a "broken MBR". This is probably why my
Soekris net5501 won't boot from hard drive.

Notice that I have a broken MBR. This is bad. I've never seen this
happen before.
Here is my partitioning and slicing information:

What do I need to do to fix this problem? I realize this is as much an
OpenBSD problem (or more so) as it is a Soekris net5501 problem.
Is there a problem with my disk partitioning?
Is there a problem with my OpenBSD partition disk slicing?
I can provide a full transcript of the install if it will help.
Thanks In Advance,
Ken Hendrickson
