OpenBSD is currently installing (flawlessly so far) but I think I'll know
in approx an half hour if I can boot the installed OS.
OpenBSD has sized the a partition with 900Mbytes so all the needed files
for booting should be below 1 GB.
The other thing you have to worry about is dumping. VMS uses the console
ROM routines to write system dumps and these can end up in the wrong place
on disks larger than 1GB on VS3100s. I don't know what unix does but if it
has a dumpfile, it would be good to keep it below the 1 GB line also.
