Thanks for the quick answer.
Somehow the PXE firmware manages to load PXELinux
properly, it's the pxelinux that can't load anything
(of course, using the PXE stack).
As far as I can tell, the tfpt transfer for pxelinux.0
starts with the same "code 6" from the server, followed
by a "packet 0 ack" from the client. Another difference is that the
pxelinux.0 load uses the proper tftp server IP,
but the "cfg" load does a full broadcast. Could that be
the problem?
The firmware is the only one I can find since the MB is the Supermicro
X5DPE-G2, it hasn't been around that long.
