How do I switch the start up disk on my G3

I recently developed a problem where my Blue and White G3 Power Mac will not start in OSX. It starts but then displays a screen that tells in four languages to restart my machine. When I restart I just get the same message.

This all started when I switched from booting in OS 9 to OSX. Both had worked in the past. Now I cannot return to OS 9. Is there a short cut of keys to press to bring up the start up disk control panel during start up to try switching back to OS 9?

Tiger Requirements...

To use Mac OS X 10.4 Tiger, your Macintosh needs:

* A PowerPC G3, G4, or G5 processor

* Built-in FireWire

* At least 256 MB of RAM (I recommend 1GB minimum)

* DVD drive (DVD-ROM), Combo (CD-RW/DVD-ROM) or SuperDrive (DVD-R) for installation

* At least 3 GB of free disk space; 4 GB if you install the XCode 2 Developer Tools (I recommend 20GB minimum)

Leopard requirements/10.5.x...


* Mac computer with an Intel, PowerPC G5, or PowerPC G4 (867MHz or faster) processor


minimum system requirements


* 512MB of memory (I say 1.5GB for PPC at least, 2-3GB minimum for IntelMacs)

* DVD drive for installation

* 9GB of available disk space (I say 30GB at least)

Trouble is Apple no longer sells it, check eBay & such for the Retail version, not the Gray Discs...

There are workarounds if the 867MHz is the only hangup...
