I pulled out the Matrox boards and reseated the others. I now get to

command I want to boot from the hard disk or the 5.25" floppies--is
that correct? Does it need an argument?

The M7195 appears to have two EPROMS, labeled
145E4 and 146E4, which
Google seems to say is the correct rom set for a /73
Those are the MXV11-B2 ROMS and have a good few bootstraps on them. As
long as you're not starting with the CPU halted, they can be run at
power-up. There are however plenty of jumpers on the M7195, some of
which you may need to fiddle with.
If you have all drives disconnected, it should drop you to a BOOT>
prompt eventually (this can take a while and hitting Ctrl-C can speed
things up). With a bootable device connected, the ROM code will even
detect and boot it for you.
