I tried to install Mac OS 9.1 on my iBook/500 with Mac OS 10.3.5. When the OS 9.1 cd booted, it said "bus error", hold shift to disable extentions. I did this and got the same result. Someone told me to press the reset button near the av port and zap the PRAM 3 times. I did this and now OS X won't boot. I just stays with the white Apple logo in the middle, no spinning boot logo or anything. Anyone know how to fix this? I have an iMovie project in the works and don't wanna erase the HD now.

Was the version of OS 9 you tried to install the version on the CDs that came with your iBook?

Anyway, to get back into OS X, I'd boot from the OS X install CD, choose Startup Disk from one of the menus, and select the OS X system folder on your hard disk.

I solved my own problem. If anyone cares, I held the option button and selected the right drive. Last time I take advice from that guy. Still can't get OS 9.1 to install. It *might* have to do with the logic board repair Apple did.

I never got the disks. I got the computer used. I was using an "iMac OS 9.1" disk, which let me install the first time.

There's the problem. The iBook 500 was introduced after OS 9.1 was already on the market, which means that the stock 9.1 install will not have support for the iBook 500 built-in. You might be able to get it to work as the Classic layer, but I can't guarantee it.

The version of 9.1 that came with the iBook would have included a special version of 9.1 with the necessary changes made so that it would support your iBook. Unfortunately, the person who sold you the machine did you a great disservice in leaving out the install discs. If you know this person, I'd go ask them if they could find the install discs and give them to you. If you can't get them, you might be able to make it work by downloading the 9.2 update and running it on your installed OS 9 system. Of course, you need to find a way to successfully boot into OS 9 to run the update. If you can boot from the OS 9.1 CD without crashing, that might be a way to do it. Otherwise, if your 9.1 System Folder will work in the Classic environment (something I've never tried, so I can't guarantee that it will work), then you can run the 9.2 update from in there.

Altight, I'm going to try copying the Mac OS 9.1 folder off the disc and try use it for Classic. I'll post the results here.

And�It works!! I copied the System Folder from the OS 9.1 install CD to my hard drive. Then I went into the Classic preferences and selected the System Folder. I clicked start and crossed my fingers. I got a few messages about upgrading to Mac OS 9.2, upgrading QuickTime and something about changing some thing in the System Folder.

Great! I was hoping that the incompatible hardware would be less of a problem in the Classic layer since much of the hardware is abstracted away. What I would do at this point would be to start the Classic environment from the System Folder on the 9.1 CD, then do a full 9.1 install on the partition that will hold OS 9. Next, download the 9.1->9.2.1 update:

and also the 9.2.1->9.2.2 update:

http://docs.info.apple.com/article.html?artnum=75186

and install them both in the Classic environment. Now, cross your fingers and try to boot from your OS 9 partition. I can't promise that this will work, but you've got a chance. If it doesn't, you'll have to get the iBook install CDs somehow. Once you do boot from the OS 9 partition, run Software Update and install whatever shows up. After this, you can probably just turn Software Update off since I doubt there will ever be any more updates for OS 9...
