Further historic chatter on this subject is in the archives at:
	http://mail-index.netbsd.org/port-vax/1997/07/01/0004.html

And from the microvax FAQ I found at 
		http://anacin.nsc.vcu.edu/~jim/mvax/mvax_faq_text.html

   8. FAQ. What is the largest disk I can put on a mVAX.
      Ans. The system disk is limited to 1 gig (there is a addressing
      limitation in the boot prom.) Non-system disks are limited to 8 gigs.

This may have been a VMS limitation at one point, but certainly not with
OpenVMS 7.2 which I run as well,  I have both 1.5 and 4gb drives on a 
Vaxstation, and a 1.5gb VMS drive on a MicroVax II.

I don't believe the 8gb limitation to be correct anymore either, but I
don't have tangible proof of that.
