   I am in the process of bringing up 4.1bsd UN*X on our second VAX 11/780,
using the distribution tape from our first one.  The problem is that the
system only sees 8M of our 16M memory.  I thought I had isolated the
problem to the following lines in locore.s:

/* count up memory */
	clrl	r7
1:	pushl	$4; pushl r7; calls $2,_badaddr; tstl r0; bneq 9f
	acbl	$8096*1024-1,$64*1024,r7,1b
9:

   I doubled the limit from 8096 to 16192, and this is what I got when I tried
to bring up the new system:

. . .
Berkeley VAX/UNIX . . .
real mem 16579584
panic: sys pt too small
. . .

   What is going on?  Can anyone help me?  Replies to me, I'll summarize
results if anyone is interested.
