First, Grant, thank you for taking the time to help me out.
I'm sure that you have other things to do besides help each
new person to get paride stuff working and I really appreciate
the time that you put into that (and into the paride project as
a whole).

Yeah, by the time I actually sent this message I'd finally worked that
out, but I sure wasted a lot of time thinking that the device or file had
been locked or something of that ilk just because the message sounds
so sure of itself. Something like "unable to initialize device" would be
a lot more helpful.

Thank you. If I can get pg to initalize again, that'll probably be just
what I need; alas, I've only gotten that to happen once.

I suspected as much but was trying to be complete. Thanks for the
clarification.

(*oops*.) I knew that once FWIW, verbose=2 and verbose=on seem to
produce the same results.

The theory was that there might be some OS build version numbers
or something else buried in there someplace . . . I suppose that it was
pretty obvious that the console font wasn't terribly relavent, though.

The only prior thing I'd done with it was to try to insmod pg once
before and have it fail, but next time I will be sure to set verbose to
2 before I do anything else.

Thats odd because I *did* power off the computer and go into the BIOS
and set the port to "SPP / EPP" mode. Alas, there is no "EPP only"
mode. Is there some standard way to be sure of the mode and/or to
set it? A pointer the right faq info would be highly cool.
(I tried grepping for EPP in both the FAQs and HOWTOs but didn't
find anything.)

I'll try disconnecting and powering off everything and doing a verbose=2
as soon as I reboot next time.
Thanks again, Mr. Guenther, and if anybody else has thoughts and
suggestions I certainly welcome them.
Again, the "device busy" message happens for both the 7500 (pg) *and*
the Sparq (pd), so something more fundamental than just the 7500 bug
is going on . . .
