Okay, so the floppy doesn't work. Not a biggie, I've taken to trying to
do a network installation. 

I setup ISC's dhcpd on my Caldera 2.3 box, with the following
configuration:

host blossom {
        hardware ethernet       08:00:2b:e5:77:ce;
        fixed-address           192.168.69.2;
        option host-name        "blossom.greebo.local";
        filename                "netboot.netbsd.alpha";
        option root-path        "/usr/local/export/alpha";
        option domain-name-servers      192.168.1.1;
        option broadcast-address        255.255.255.0;
        option domain-name      "greebo.local"; 
}

I then started up dhcpd, and it's offering properly; my laptop and my
housemate's laptops both picked up addresses from the dynamic range I
set up. 

The alpha, when booted using 

boot -proto bootp ewa0

Sends out a broadcast, the Linux box sees it, and sends back a properly
formed bootp response. This is the output from tcpdump:

01:17:45.700361 0.0.0.0.bootpc > 255.255.255.255.bootps: xid:0xa47080f4
secs:8 [|bootp]
01:17:45.701470 catwarmer.greebo.local.bootps > 255.255.255.255.bootpc:
xid:0xa47080f4 secs:8 Y:blossom.greebo.local S:catwarmer.greebo.local
[|bootp]   

So why's the boot prom not going to the next stage and trying to pick up
the image from tftp? Beyond dhcpd, tftpd and nfs working, what else
needs to run to make the 2nd stage booter pick up cdhdtape from the
network?

Hint 1: dns is not yet working. blossom is being picked up cos I stuck
it in /etc/hosts. I'm working on DNS, but my copy of the 2nd edition
O'Reilly DNS book has gone walkies, and using the 1st edition is not
helpful.
