We recently installed a second memory controller on our 780, expanding
our memory from 4Mb to 8Mb. The DEC man is convinced the hardware's OK,
since VMS sees it.

However, neither 4.1 nor 4.2 BSD can find the new memory.

From our console log (at boot time) when we had only 4Mb:

real mem  = 4193280
avail mem = 3675136
mcr0 at tr1

...and now we get:

real mem  = 4193280
avail mem = 3675136
mcr0 at tr1
mcr1 at tr2

The new controller is found, but not the new memory!

Seems I recall something about this a while back in this newsgroup.
Does anyone remember?
