Recently, a friend called for help with his PC. He was having trouble booting it up. It turned out to be an issue with his cpu/mb where it would not boot with even level 1 cache enabled in bios and XP was able to boot without it, but too slow to be useable. The PC was his file & print server for his small home office. I popped in a Knoppix CD, was able to boot up AND use it. I also edited the samba.conf & cupsd.conf files and voila, he had his file & print server back. The PC also had a dvd-rom drive & cd-rw drive. We booted Knoppix off the dvd and backed up his files on the cd-rw using K3b which is included with Knoppix. K3b is easier to use than either Nero or Roxio. This was just a temporary solution until the replacement hardware arrived, but a very impressive one at that.
