OK, I chose a screen resolution through the OS 9.2.2 control strip 
that isn't supported by my monitor. Now I can't see the screen. I 
booted into OSX, deleted the montior preferences within the OS9 
system folder but when booting into OS 9.2.2 it still is going to the 
unsupported resolution. How do I get it to go to a supported 
resolution without being able to see the screen???

Apple Care tech support was incompetant and couldn't help me. Their 
suggestion: I obtain another monitor for the purpose of switching 
resolutions.

Please help ASAP!

Thanks!

You could try zapping the PRAM:

http://docs.info.apple.com/article.html?artnum=2238

1. Shut down the computer.
2. Locate the following keys on the keyboard: Command, Option, P, and 
R.  You will need to hold these keys down simultaneously in step 4.
3. Turn on the computer.
4. Press and hold the Command-Option-P-R keys.  You must press this key 
combination before the gray screen appears.
5. Hold the keys down until the computer restarts and you hear the 
startup sound for the second time.
6. Release the keys.

Further down the page it says that the PRAM stores the Monitor Depth, 
but there's no mention of resolution.
I guess it's worth a try? I did the same thing myself once (only under 
X) and I ended up using a second monitor, as I was fortunate in having 
one around. I guess a last resort would be to power down, and remove 
the internal battery for a few minutes. I've no idea if this would work 
becaaue I'm not sure where or how the monitor resolution is stored. As 
you've already tried removing the prefs, I guess stuff like this is 
worth a go?

And if that doesn't work (and I suspect it won't, but I might be 
mistaken), then maybe you can boot into X, remove the entire 
Preferences folder from the OS9 System folder, and try booting into 9 
again.  It might be that monitor resolution is stored in some other 
prefs file, such as Finder preferences or what not.  Afterwards move 
the 'obvisouly innocent' preferences-files back to the newly created 
Preferences folder.

If all that still doesn't work: boot into X, start the Script Editor 
and put it in record mode.  Switch the monitor to some (supported :) 
resolution, and save the recorded script as an application (just hope 
that res-switching is indeed being recorded).  Now put the script 
into the OS9 > System > Startup Items folder and boot into 9.  The 
script should execute and switch the monitor-resolution.  Then remove 
it from the Startup Items folder.

Strange that it's such a problem in a user-friendly Mac world ;-) on PC you just start up Windows in 'VGA or Safe Mode' and change the resolution..
Strange there is no analogy in Mac world.

What amazes _me_ is that the problem can occur in the 1st place.  If 
I switch resolution on my konitors, I get a dialog (after switching) 
asking if this is okay or not.  The 'Cancel' button is the defult 
here, so if I ever attempted to switch to an unsupported resolution 
so that everything becomes a blur, I would simply hit 'return' and 
all would go back to normal.  Since I use the standard Mac OS Monitor 
control panel, I would expect it to behave similar with other 
monitors...

You're right as well though -- it _is_ weird that this is a tough one 
to solve once the damage is done...

Just hit the esc key. This has always worked for me in the situation of 
selecting an unsupported res.
