S$%t.  I'm using 2.3.40.

Ok, I think I'm close, but you may have to help me a little with DHCP
(sorry for some reason it's something I always have trouble with).

Here is my entire /etc/dhcpd.conf on 192.168.0.4:

option subnet-mask 255.255.255.224; # 255.255.255.0???
default-lease-time 600;
max-lease-time 7200;

subnet 192.168.0.0 netmast 255.255.255.0 {
  range dynamic-bootp 192.168.0.200 192.168.0.210;
  option routers 192.168.0.4;
  option broadcast-address 192.168.0.255;
}

This is the only DHCP server running on my tiny network.  When I do a boot
from net on the Raq4, the following lines are printed to
/var/log/daemon.log on 192.168.0.4 (aka skinner):

Apr  9 20:53:00 skinner dhcpd-2.2.x: BOOTREQUEST from 00:10:e0:02:59:13
via eth0
Apr  9 20:53:00 skinner dhcpd-2.2.x: BOOTREPLY on 192.168.0.200 to
00:10:e0:02:59:13 via eth0

And here is the output from the Raq:

Looks like it's close, any thoughts?  I'll start reading dhcpd man pages...

FYI, before I wiped out the Raq, I used the LCD to set the IP address to
192.168.0.6.  Not sure if that is pertenant.

Ok, if the boot from net option doesn't fly, I guess I can try to build
Debian again and try this option...

Thanks!
