Hi Pat, My Altos586 is in the same boat as Scotts - it boots OK from the hard drive, but I don't have install media should I ever need to rebuild it. The one disk I have on my site was "stuffed into the drive" when I got it, but I don't think it's enough to reinstall the system. Please let me know if you locate the Altos install disks - I'd also be happy to include the images in my archive if thats OK with you.
