There isn't a DOS-based RAM diagnostic worth spit, and the good ones admit this. They will detect serious RAM errors, but timing issues are beyond anything that can be casually tested. > I think it could be having problems, the disk is a Seagate Hawk ST > 31230N, the real geometry is 3992/5/103 we have tried 1010/64/32 (DOS > likes this) and 998/40/51 with no success.

Definitely a hardware problem. I'm coming in on this late, so a quick list of CPU, motherboard, chipset, disk controller would be helpful. If you're only going to have FreeBSD on the machine, use the 'all disk, no' option to avoid any geometry issues at all. > Kevin Quinlan -- ]] Mike Smith, Software Engineer msmith@atrad.adelaide.edu.au [[ ]] Genesis Software genesis@atrad.adelaide.edu.au [[ ]] High-speed data acquisition and (GSM mobile) 0411-222-496 [[ ]] realtime instrument control (ph/fax) +61-8-267-3039 [[ ]] Collector of old Unix hardware.
