trying to netboot G5 Xserve HPC node

[Chris Friesen]

I've got an HPC G5 Xserve (the one with no CD drive), and I'm attempting to boot
linux on it.

I've got dhcpd V3.0pl1 running on a G5 desktop (/etc/dhcp.conf included below).

When I try and netboot the Xserve, it appears to issue a bootp request, the
server sends a response, but the IP address offer is never accepted.  What am I
doing wrong?  Is there any way to get the Xserve to show firmware boot logs on
the serial console?

The logs on the dhcp server look like this:

Jul 19 18:03:57 g5-2 dhcpd: dhcp.c(2072): non-null pointer
Jul 19 18:03:57 g5-2 dhcpd: DHCPDISCOVER from 00:0d:93:9b:a8:6c via eth0
Jul 19 18:03:57 g5-2 dhcpd: Received BootP request from Macintosh netboot client
Jul 19 18:03:57 g5-2 dhcpd: DHCPOFFER on 10.40.200.5 to 00:0d:93:9b:a8:6c via eth0
Jul 19 18:04:01 g5-2 dhcpd: dhcp.c(2072): non-null pointer
Jul 19 18:04:01 g5-2 dhcpd: DHCPDISCOVER from 00:0d:93:9b:a8:6c via eth0
Jul 19 18:04:01 g5-2 dhcpd: Received BootP request from Macintosh netboot client
Jul 19 18:04:01 g5-2 dhcpd: DHCPOFFER on 10.40.200.5 to 00:0d:93:9b:a8:6c via eth0

Any ideas?

   #you may paste another "host" entry here for additional clients on this network
