Help needed...VAX 7000 mop booting problems

[Patrick Finnegan]

So, I've been trying for a few days to get my VAX 7000/640 (currently 
with only one processor, so a 610 I guess) to MOP boot into a VMS 
cluster.

I'm running OpenVMS hosted off SIMH, and have tried both 7.2 and 7.3, 
and have successfully booted my VAX 4000/100 off the setup.  I've also 
successfully booted the firmware update utility (LFU) and the 
file "ISL_LVAX_073.SYS" that comes on the install CD, through MOP.

However, when I try to do a mop boot, the system just halts and says 
boot failure:

I've tried it omitting the -flags part, and with -fl 1, but they all 
give the same error.

Anyone have any useful hints?  Or, another VAX 7000 to try repeating my 
(failing) experiment on?

Thanks,

Pat
