} }

     I tried this.  It didn't work, the server didn't respond at all.
Also, after I tried this, the Win95 box was unable to get a new lease
for a while as well.  Actually, this line violates RFC 2132, which
says that the first byte of the dhcp-client-identifier is a code byte
that specifies what type of identifier it is.

} I think the dhcp-client-identifier has to be the "csxxxxx-a" thingy, no?
} (I don't think it cares what ethernet card is hooked up, as I've never had to 
} specify a MAC address anywhere...)

     I was simply duplicating what the Win95 box did, since it works.
