However, I suspect Doug has the kind of system that will do a make world in a minute or two. You should run "make world" to verify your test results, but if you've just plopped in a new SIMM, making the world is just too heavy. > > Any pointers to nightly reading material?? > Since FreeBSD systems will start pumping out random signal 11's in the face of bad memory, try searching the -hardware and -questions list for that. I believe that someone actually wrote a signal 11 FAQ, but I don't have a pointer. There is a (Linux) program named memtest that will do just what you suggest. You can dd(1) the binary onto an unused 1 meg partition and have booteasy drop you in without even touching an OS.
