Has anyone done this successfully?  I've given the netboot
diskless faq a number of good readings.  What I'm doing on
one AS1200:

boot -protocols BOOTP ewa0      (a DEC500 device)

I've got bootps and tftp configured on a server machine.

However, when I attempt a boot, (with debugging output)
I see this on the server

Mar  8 06:49:50 server bootpd[6977]: recvd pkt from IP addr 0.0.0.0
Mar  8 06:49:50 server bootpd[6977]: bootptab mtime: Fri Mar  8 06:48:15 2002

I do have a proper map to 'client' for that IP address in /etc/hosts

There are no error messages that I can find.  These debug messages
occur each time a probe take places.

any ideas?
