G3 Snow refuses to boot OS 9 (I've tried everything).

I have a troublesome iBook G3 Snow that I've been trying to diagnose ever since I bought it nearly 2 years ago. It's a 600MHz "16MB VRAM" model (12 inch), and it seems to work just fine. I've ran OS X Jaguar and Tiger on it with no problems. The Classic Environment also works as expected. Just one issue - it won't run OS 9.

It's been a while since I've messed with it, but here's a list of everything I remember trying.

1. Booting from an OS 9 disk to install. This iBook's CD Drive is incredibly finicky when it comes to booting from burned disks, so for the longest time I haven't been able to try installing the standard way. I once managed to boot it from a disk, but it was 9.2.1, and refused to install as it wasn't supported. I needed 9.2.2. I haven't been able to get it to boot a 9.2.2 disk (or any burned disk for that matter) since.

2. Copying over a known good system folder and trying to boot from it. OS X's startup disk selector detects it, but after trying to boot from it, it stops and gives me a blinking question mark over a floppy disk icon. Important note: This is over a floppy disk icon, not a folder like the iBook's firmware would normally display if it can't find a bootable disk - this was a floppy disk. I believe this is simply down to a failed boot. The iBook displays the folder if it can't find any bootable device The only way to escape this boot error is to put the iBook in target disk mode, mount the drive on another computer, and set that computer to boot from the OS X system on the volume. Then it will boot OS X again from the iBook.

3. Installing OS 9.2.2 using the classic environment on OS X. The install finishes successfully, but it displays the same issue as #2.

4. Installing OS 9.2.2 from a bootable disk via booting it on another computer (my TiBook or iMac DV SE), and mounting the iBook's drive in target disk mode. This also yields the same result as #2.

5. Trying to boot a known working OS 9.2.2 install via mounting a different computer's drive (my TiBook or iMac DV SE) on the iBook and booting from that. This works fine! 9.2.1 or 9.2.2 if I remember both ran. But I just booted 9.2.1 to confirm it works - it just won't do it from its own drive.

That's all I've tried, but what else is there to try? Has anyone seen this before?
Just one note - I've once managed to get it to boot 9.2.1 via copying over a system folder. This was a long time ago, and I remember it running at a low color depth (due to being 9.2.1 not 9.2.2), and it being extremely unstable and prone to crashing. I'm not sure if this was due to it being 9.2.1 or something else.

Thanks in advance for helping me troubleshoot this one - it's been a real doozy.

Did you format the hard drive with OS 9 drivers in place? It almost sounds like the drive only has the OS X driver installed.

I believe so. OS 9 installers that I was able to get running were able to detect the drive to try an installation at least. Is that enough to verify so? If not, is there an easy way?

I agree with Volvo, that is the most likely issue. Start up your Snow in Target Disk Mode and connect to your TIBook or DV SE via FireWire. If you can do without what is there, use Disk Utility on the Ti or DV to erase the Snow's internal HD, and make sure the "Install Mac OS 9 Disk Drivers" check box is checked. Then, copy the 9.2.2 folder onto the Snow. The only other thing I can think of is you may have a Mac OS ROM file in your OS 9 System Folders that the Snow is not compatible with. One way around that would be to fresh install a retail 10.4 installation on it with OS 9, and that should have the proper ROM file for any Mac that it can run on.

Well, that news is both good and bad. Good because hopefully this will actually work, bad because it's going to be a huge pain reinstalling all of my software that I had to transfer over the USB 1 bus...

I'll give it a go and see. Hopefully it's that simple of a fix.

1. Hook it up to my iMac DV SE and put the iBook in target disk mode.
2. Boot the iMac from an OS X Jaguar disk and used the disk utility to repartition the drive with the OS 9 drivers checked
3. Got the tweezers out to wrangle my Jaguar disk free from that iMac's non-ejecting drive
4. Booted the iMac from on OS 9.2.2 disk
5. Installed on the iBook's volume

And that worked. I always check the OS 9 drivers box, so I'm surprised that was the issue. That and the fact that that volume always seemed to mount fine on OS 9, it just wouldn't boot it. Well, it works now!
