One suggestion I got was that the diagnostic floppy could have have been trashed, and suggested I test this with booting off Foundation set #3. (thanks to Peter Schmit) Well, this disk booted!. So I grapped the s4 diagnostics and Thad's install script. I created a new, bootable diagnostic floppy. THAT won't boot. (it, and the munged diagnostic both boot on hico2, and while the bad diagnostic disk won't load properly on hico2, NOTHING works right with either disk on ailing hico3.) I'm wondering what I did wrong, what's different about the diagnostics disks (and hico3) that they won't boot in hico3, but Foundation set #3 will? Kris A.

Ok, I think I've got past this. I started to try to create a diagnostic disk by hand, and I had done the /etc/iv. Then I got Thad's previous script, and used that to re-make the floppy. If I understand correctly, Thad's script forgot to put a loader on, so maybe there was some kind of remenent of when I did the first iv. The original diagnostic floppy might have had a bad block somewhere in the boot area, the first time it failed the surface test with drive 0 track 0 sector 0 bad. (or whatever, all zeros) I'm not sure why the double-written diagnostic disk would boot on hico2 and not on hico3, but it could have been an artifact of its odd upbringing. I re-made the diagnostics disk using instructions from Peter Schmidt (...mit-eddie!winter!pschmidt)(Thanks again!), and the new diagnostics disks worked fine! (one I had to make twice). I'm also putting a write-protect tab on everything. Sooooo, now the floppy disk works and the hard disk doesn't. At least it's a simpler problem.
