Try googling on it? You might find, oh, about 641,000 hits.... It tests system memory (but *not* the video card!). You cannot run anything else while it's running: you boot from the floppy or cd (the Knoppix live cd comes with it as a boot option), and you let it run. Overnight is a good time, though if you're really in a hurry, maybe two hours. It will let you know if there's harware errors in your memory. You *should* have it in your toolbox as a sysadmin. BUT IT WON'T DIAGNOSE THE VIDEO CARD! mark -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subject=unsubscribe https://www.redhat.com/mailman/listinfo/redhat-list
