	Thanks for the suggestions!

It turned out that I forgot to configure the netmask in the bootp 
server to 255.255.255.0.  You see, I was not using a unix box as 
bootp/tftp server.  Instead I am using a Windows 98 machine for the 
deed (ok, it is actually a Virtual PC section in my Macintosh ;). 
Reason for that is that I wanted to see if I could do that, perhaps 
even write down a how-to so others will be able to repeat the feat 
with an easily-found Windows machine. =)
