A handful of observations:
1. A 9500 is now old enough to have capacitor failure. Sorry, but it's just possible.
2. I acquired an 8600/300 a few years ago that exhibited the same symptoms on first boot, or non-boot if you like. Perseverance paid off, however, and it has not failed since despite intensive use. Prior to coming into my hands, it had been sitting on a shelf unused at a dealer for an unknown time - months, at least. I suspect that the problem must have been PRAM related, but who knows? The moral of the story is that something in the machine needed to be reawakened, and that took some fiddling.
3. Have you tried booting from a floppy or from a CD?
4. Are you absolutely sure your scsi settings are correct? The symptoms are consistent with "scsi voodoo."
