dhcpd/bootp and 405 (walnut)

[Jer_57]

I know this has been discussed before, but I can't find a solution in
the archives.  We are trying to get some IBM405 (Walnut) boards to
boot with dhcpd but not succeeding.  We can boot them via bootp
though.  The version of dhcpd we have installed is:

[root@vail root]# rpm -qa |grep dhcp
dhcp-2.0pl5-8

from RedHat 7.2 install.

Does anyone know why this might not be working?  Is there something
we need to add to the dhcpd.conf file?  We have other boards booting
from dhcpd just fine (mbx860/821).

TIA

I believe that the problem is that OpenBIOS is doing a DHCP request
directed to a specific IP, but the response that that particular
dhcpd does is to a broadcast address instead of directed back to the
IP that sent it.  You can verify that using tcpdump or ethereal.

This is fixed in the 2.0pl5 available from isc.org, but the 2.0pl5
in RH7.2 seems to be broken in this regards.
