Johnny, you're insisting that I put in the
real numbers for address
and csr
for testing the drive (for instance). I'm going to do that next, here.
But are you understanding that some of us think that the reason it
prompts
a zero default is that it's a manifestation of the zero bug and that the
real value *is* actually safe but hidden in memory? Did you see the
RSX-11M crash dump I posted in the other thread?
I didn't see a crash dump, but did you see what I posted yesterday? The default in XXDP for CSRs is very often zero, and
I'm pretty sure it
is so in the RL02 diagnostics (I've ont checked the listing for that
particular one, but I did look at some others that were more readily to
hand). So when it asked you for input and you just hit "return", you
really did tell it zero. Applying the principle of Occam's Razor, and
assuming the simplest solution is the correct one, you got a lot of
zeros back because it was accessing memory instead of the controller you
wanted.
It's hard to believe you have a CPU fault that consistently prints
numbers as zeros yet happily boots three different OSs. Still, I'll
change the tune if you re-run XXDP with sensible inputs.
Totally agree with that one.
Johnny
