Fix for 4.2 not seeing all vax memory?

[ted%bragg1 at braggfs.arpa]

Hi folks,

We are in the process of bringing a virgin 4.2 distribution tape Vax 780
into the world.  We have 10 Meg of memory on it, but 4.2 doesn't see all
of it.  I remember reading of this as a known bug and remember seeing a
fix for it; but at the time I was sure I would never work on a vax with
that much memory and I didn't save the message (dumb, I know). Does anyone
have the fix handy?  Also, is there an archive of 4.2 bug fixes in general?

				Thanks
