I have a 3/470 and a 2/120 that will serve a diskless Sun2 client. The
daemon ndbootd is included with SunOS for both the Sun3 and Sun2
architectures. The only thing that ndbootd supplies is the Sun2 TFTP
program. (It wouldn't fit in the boot ROMS.) Once the TFTP program is
loaded the Sun2 boot looks normal.

I can give you a TCP dump with Sniffer Pro if you need it.
