Subj : 386 OS/2 Woes...

I've spent the better part of three days trying to get OS/2 up and running
on a 386DX40. It was having all sorts of intermittent errors, trap errors,
lock ups, etc. Just all around 'unstable'. CF cards that worked fine on the
486 were completely broken on the 386.

"It can't be the memory. POST says it's fine!"

After all of that, yesterday I was like, "I guess I should check the memory
out." Memtest86+ took about 20 seconds to show that something was wrong.
Swapped out the memory and it was still seeing the same kind of issues.
Turned off the cache and the issues went way. Enabled the lower bank of
cache (128k versus 256k) and it was still working without issues. Turned
back on upper bank and the problem was back. All of my issues were caused
by one bad cache chip. :)
