Can boot to Classic but won't run under Tiger

I am having a torrid time trying to get Classic to run under Tiger
10.4.2 on my Powerbook G4 (1 GHz, 512 MB SDRAM).

Basically, the progress bar comes up. I see the "Welcome to Mac OS"
screen when the progress bar is about 2%, and then it just hangs there.
(I have Classic 9.2.2 installed and it works fine if I boot into it.)

So far I have tried all of the following:
- Turning off extensions
- Creating a new user account and running classic from it.
- Deleting ~/Library/Classic and having Classic create it again.
- Turning off "Use preferences from Home Directory"
- Replacing the "System Folder" with one from OS9General.dmg on the
Software Restore disk.
- Deleting the Recent Servers, Recent Documents, and Recent
Applications in the OS 9 System folder. HD->System Folder->Apple Menu
Items.

None of the above fix the problem. Now I am clueless as to what else I
could do.

Any help on troubleshooting this will be greatly appreciated.

Thanks!

Did you open the Classic Pref Pane in X and select your system folder?

m-m

 

Yes. It's properly selected.

 

Just to be sure we are on the same page... I see the "Welcome" message
but no progress bar. It then changes the message to "Starting up" with
a progress bar. Is that what you are getting?

Assuming so, has it ever worked on this machine with this OS?

If so, when did it stop working?

It sure sound like a OS9 extension (even though you started with
extensions off), I am not sure what that really does when starting under
classic? I would try moving (temporarily) the extensions to another
folder. You might have some extension that boots OK but won't run under
classic.

BTW, just to keep the terminology correct: OS 9.2.2 is an operating
system. You boot into OS 9.2.2, not Classic. Classic is an OS X
process which only runs under OS X and starts OS 9 as an OS X process.

Have you done your backup today?

 

Yes, you are right about the terminology. My bad.

Addressing the questions you raise:

- The progress bar I refer to is the "Classic" progress bar, that show
up at the top. Not in the OS 9.2.2. In the OS 9.2.2 part (which I get
by clicking the "Show Details" arrow), I just see "Welcome to Mac OS"
screen and then it hangs.

- It (i.e. Classic) has never worked since I upgraded to Tiger. It
worked fine under Jaguar. I never needed to try it while I had
Panther. So I don't know.

- I have tried moving extensions, but I still have the same problem.

More suggestions would be greatly appreciated.

Thanks so much for all the help so far.
