I was attempting to setup a diskless workstation using linux 2.0.10
(Red Hat 3.0.3 distribution + updated RPMS) and bootp 2.4.1 (possibly
with RedHat patches? From NetKit-A-0.08), but had some problems.

The client did not know its IP address on bootup, so the server, in
order to send a message back to the client, first needed to setup an
entry in its arp table.  This was failing.

The reason it was failing was because the hardware address type was not
being passed along to the kernel.  I have included my patches for fixing
this.

Please send all responses to bgarcia@fore.com
