However, I've not had any of these systems produce errors like these. I can run the 2GB system with and without high memory support and try to induce a similar failure. Are there any specific tests you'd like me to run on this other system, in case I can't induce an Oops on it? Thanks, Gregory --=20 Gregory K.
