I knew this could be a problem, but I tried it anyway, and it worked (mostly). No amount of memory replacement or tweaking fixed the occasional problem, even though that is exactly what the problem looked like. It worked fine 99.9% of the time, but at least once a day it would crash hard. When I popped in a regular old Pentium processor that I knew the board could support, it worked flawlessly for weeks. When I put the Pentium-MMX into a newer board that supported it, it worked flawlessly as well. So, other than memory, you should check out both your motherboard and CPU. Try underclocking the CPU and see if that fixes your problems. -- Chris Dillon - cdillon@wolves.k12.mo.us - cdillon@inter-linc.net FreeBSD: The fastest and most stable server OS on the planet.
