This has occurred on every install try. This is almost certainly a hardware problem. > Machine config: > > 486 DX2/66 > PVI-486SP3 Mother Board - 3 PCI/1 VLB/3 ISA Normally I would slag your motherboard/cache hardware, however these boards are actually pretty good stuff. Try disabling the WriteBack cache option (go to WriteThrough). If this doesn't win you, set the "BIOS Default" settings. Make sure the "chipset setup" stuff is set to "Auto-Detect" too. If you're still bombing, it's almost certainly your memory. Despite assurances in the manual, make sure you're using 70ns memory parts, and that you are _not_ using a 30-72pin SIMM adapter. > What am I missing here? Should disk geometry be different?

Whatever you do, don't dump the motherboard; it's one of the faster 486 boards around 8) > Dave Slough - CITIS Network Engineer -- ]] 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.
