Hi Mike,

What you describe seems like it should be possible.

I have CC'ed the Etherboot-Discuss mailing list since your question
mentions gPXE.  You need to join Etherboot-Discuss to be able to post to
the list (we get flooded with spam otherwise, unfortunately).

I would also recommend that you visit the #etherboot IRC channel of
irc.freenode.net where there are usually a number of friendly and
helpful people around who may be able to help you.  You may need to lurk
on the channel for a while after you ask your question because people
are all over the world and thus have different schedules.

I'm sure we could help you interactively on the channel. If email works
better perhaps someone on Etherboot-Discuss will chime in and give you
some suggestions.
