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.
