This new "legacy free" motherboard seems to have removed all code to deal
with this kind of ROM layout.

Great minds think alike :-)
By the time I got your message I had already downloaded specs, extracted
ROM contents of the Intel and 3Com cards for comparison, debugged and
developed a patch for the bug. I wanted to write up a description of the
fix and how I found it before replying.

I'll include this in the message I send about this. I have a client
emergency to take care of this morning, but the bug/problem is that there
is what appears to be a typo in loader.S which causes one of the header
fields to be in the wrong place.
I'll send in a small patch for loader.S, which fixes this. The bug
exists in Netboot's code as well, so this is probably also of interest to
that list.
Regards,
Marty
