I found that, unfortunately, only Intel co-processors worked. I tried Cyrix and IIT, and both of their 80387's were not truely compatable with Intel's. The chips worked fine under DOS, but under OS/2 and FreeBSD they caused problems like you described. Anyway, putting in an Intel chip caused the problems to go away. As for your memory, it sounds like there's some bad registers in that new memory you put in. There are some DOS based diagnostics that really check the chips well. Take your new chips back to where you got them, and ask them to check them for you. -- Alec Habig, Indiana University High Energy Astrophysics ahabig@bigbang.astro.indiana.edu http://www.astro.indiana.edu/home/ahabig/ Ted Kennedy's car has killed more people than my guns.
