Hey.  you burst no bubble.  The processor replacement fixes the problem
on Transcomputer motherboards with the SX211 version of the 386 chip and
probably affects anyone with that chip version.  If you don't have that
chip version, you probably had a *different* problem.  Just hit the 'n'
key if the article doesn't apply to you.  If just one person is saved
from the particular problem which plagued me, my posting will have been
worth it.

I'm glad you got it working on your machine, really.  I tried exactly
what you describe, I pulled my drive and controller and installed 2.2
on my drive in a different box.  After the install went successfully,
I put my drive and controller back in my machine only to have the kernel
panic and dump everytime it tried to load.

NO, it shouldn't run on any machine with the SX211 version 80386.
I'll bet you don't have this chip in your box.
