Does anyone know how to get a program to run in the Supervisor mode? I am
trying to manipulate some of the on-chip peripherals of the 68070. I have
written a driver and descriptor but it does not work. Now I am writting a
simple program to try and solve my problem. If I set bit #5 of the Attr byte
then the program is in the Supervisor mode but hangs up the entire MM/1. But,
if I don't set the S bit and go into Sysdbg, I can step through the program
after setting the S bit and everything seems fine! What am I doing wrong? Any
suggestions?
Thanks
Bert Schneider
