If it's the MicroVAX you were talking of in the previous post,
with a SCSI<->MSCP converter, probably not. It's an issue
with uVAX 3100 models (below 80, I believe, but I could be
mistaken; I haven't tried with my 80 yet) which had direct
SCSI control via a 53cXX chip and handcrafted their SCSI
packets using the old 6-byte command set. Once it's handed
off to the OS, it's fine, but in my experience it's never,
ever a problem with MSCP converters (my CMD CQD-220 certainly
has no problems going beyond 1GB on PDP-11 or uVAX 3900).

I would anticipate it should work fine in all of
those - of course it
wouldn't change the 1GB boot volume issue with certain models of VAX,
since that's the VAX firmware crafting the SCSI packets.
That may be why I can't get my Vax to boot from local disk!
