Does the system folder have the special icon indicating that it's a system folder? It's possible that it isn't "blessed" properly. Reblessing it could be as simple following these directions, or it could be a nightmare to do.

* Select the "System", "Finder", and "tbxi-enabler" files
* Drag them to the hard disk icon of the partition the system folder is in.
* Drag them to the system folder. If its icon changes, success!
By "1 partition with Mac OS Tiger", do you mean that you have Mac OS 9 on one partition and Tiger on the other? If you have that configuration, it should work. If you are trying to do this with only one partition, you are going to have a lot of trouble because OSX doesn't let you set the startup disk to a Mac OS 9 system folder if the machine isn't "supposed" to handle 9.

macarone:
If you are able to boot the computer into OS X, running DiscWarrior on the partition containing OS 9 will "bless" the OS 9 System Folder, even when other methods failed.

I have never been able to figure out what makes a partition show up in Startup Manager (booting with Option held down).... Some show up and some do not, even when they DO show up in System Preferences/Startup Disk.

And, some partitions show up in Startup Manager but NOT Startup Disk.

I'd be grateful if someone explained it all.

Astroman:
can't explain it in depth, but aside from disk partitioning/driver it's the content (!) of the MacRom which is checked during boot. If the requested resources are missing, the whole disk will be excluded from the list of bootable drives.

That works too. I just have never done this stuff from OSX.
