Yes, I got the old shared memory working.
I'll have to check the
mknod /dev/mbuff c 10 254
I thought of that after I sent the message and I was already gone from
the
office. I'll update either later today or Monday.
Thanks --

Janet:
Did you create /dev/mbuff??
mknod /dev/mbuff c 10 254
BTW: did you get the (old) shared memory working??
