This looks very similar to the problems I was having boot strapping my box.
I solved the problem by putting the to machines on a very simple network.
All there was was two boxes.  My HP and the Linux box I was booting off of.
The HP never seemed to get all of its boot information because the
building's network had more traffic than it could deal with.
