} 1) Try using the -vVdD flags and see if ofwboot.net is more loquacious.
Use these flags where? With what command?
} 2) Instead of using boot, do:
} ok load-base dload ofwboot.net
} Then look at what you've got at load-base (load-base 1000 dump). Once
} you know the right data is there, you can `go' to execute it.
What should I expect to see?
Actually, given that Andrey's machine booted, I'm starting to
suspect that my machine has problems. I just replaced a blown power
supply (it is/was plugged into an APC SmartUPS 1400, so the power
should have been good; however, I can speak to what the previous owner
did with it). At the same time, I took the opportunity to stick in a
second processor and additional RAM. I'm starting to suspect that I
may have another bad component.
