Okay.  There are a series of HP servers for which localboot 0 is never
going to work with gpxelinux -- and very likely not with any newer
pxelinux either.  This is due to a very serious software bug in their
BIOS which is almost impossible to work around.

The strange bit, though, is why chain.c32 isn't working.  That operates
through a completely different mechanism which is supposed to be more
robust.
