Loss of memory

[Mark Hastings]

I am having a problem with Ultrix 3.1 on some new DecStation 3100s.

These machines have 24MB of RAM, and the hardware tests seem to find
and test all of it.  But when vmunix starts up, it can only "see" 16MB
of it.  The generic kernel also fails to see this memory.

Have I missed some simple configuration option, or might we have a hardware
problem (the DEC hardware and software support people are pointing fingers
at each other).
