Hi All,

I'm trying to netboot a completely functioning Maxine (Digital Personal
DECstation 5000/33) by either MOP of TFTP.

I've installed a mopd from -current on a NetBSD/sparc and have put both
ecoff images in /tftpboot/mop and /tftpboot itself, but it won't boot. The
PROM version is `KN02-CA V2.1a'.

When trying `boot 3/tftp' it stops with `?IO: 3/tftp, bootp tmout' while i
do see bootp messages going from my sparc addressed to the DEC. It looks
like it doesn't recieve the bootp answer... while the sparc sends 5
answers on a quiet network.... tftp isn't initiated. I copied and modified
the bootp record from the netbooting page.

When trying `boot 3/mop' it keeps trying to fetch with mop. moptrace
give's the following output : "

" over and over again

and the mopd itself (run by mopd -d) gives : "

" over and over again.

Sometimes i do get a "

" when tftp-ing ??? but only very rare... 

I can see the MOP-messages going back to the DEC, but again... it doens't
seem to listen. Running `pst-t' doesn't report any errors and it runs
quite happily under NetBSD/pmax 1.4.1 with full network facilities.

The reason for netbooting is that the internal SCSI harddisc is making so
much noise ... that i don't want to switch the machine on! Ouch.. my
ears.. 

Any help would be very apreciated!

Thanks in advance,
