Doesn't suprise me. Generally speaking, software based diagnostics for DOS suck. > My questions: > Is the "RAM parity error" in FreeBSD 2.0 (2.0-950322-SNAP) reliable? I would guess that message comes from your BIOS, and not from FreeBSD - but I could be mistaken. I would think that if FreeBSD detected an error of this sort, it'd force a panic. > Do you know of a real(!) good hardware (memory) testing utility, maybe under > dos? The only decent memory testers I've seen are dedicated SIMM testers - they are not cheap, and even so they don't detect all problems. Check your "CMOS setup" against the manufacturer's recommended settings. You might also try swapping out some of RAM to try and isolate the problem.
