- Ick, sounds nasty. I assume that you have run diagnostics on the
- system board? Two things come to mind when I head NVRAM sanity failures...
- 1) the battery was disconnected while the power was turned off, OR 2) the
- system board has been removed from the backplane. I suppose, now that I'm
- warmed up...that an intermittant ground could cause the same thing.
- I'd take a shot at finding a system board that you could swap out for a
- short period of time and then take the machine up and down a few times...
- could be the problem will go away. Yeah, I know, you probably don't have
- a spare in your pocket, but the at&t/ncr folks probably should have tried
- this if the battery fix didn't work.
