Force startup in OS X

It depends what computer you have.... not all can be forced the same way. If both systems are in the same volume, press Command-X when starting up. Also, on my Quicksilver, pressing the option key at startup brings up a screen that allows you to select a startup disk/system.

I have never tried the Command-X combination. I will have to give that a try. Doesn't the option key method require the two operating systems to be on separate volumes? I have both OS X and OS 9 installed on one volume, and it never worked for me. I have not tried it recently though.

Not on any of my Macs. Holding the Option key allow me to choose the startup _volume_ but each volume only offers the OS which was last specified for it with the Startup Disk control panel/system preference.

Doesn't that require the operating systems to be on separate volumes? It has not worked for me with the two operating systems on the same volume.

What I just said above.

You're welcome.

IIRC, I think that it does because I have only one OS 9 and that is on the same volume as the Panther I use most of the time. However, it may not work on all computers.

I've never used "CMD-X." Simply holding down "X" will cause restart from OS 9 into OS X, but only if the systems are on same partition or a non-partitioned drive. If restarting, it has to do two "starts" while the "x" key is held. If 9 and X are on separate partitions, you need to use the "option" key method as described earlier. --

If I was previously started up in OS X, but want to boot in OS 9, what key combination can I use if both operating systems are on the same partition?

None. Holding down the X key (note: you do not need to hold down Command-X, just X alone) forces a reboot using X, but Open Firmware has no provision for forcing a reboot in 9. Sorry...

There is no key combo for a reboot from X to 9. Instead, simply open System Preferences>Startup Disk, select OS 9.x system folder; click Restart.

Thanks for the information.

Jeff

Yes, I know. I am almost always in OS X. But, there are times when I know I need to get into OS 9, and would prefer to not wait for OS X to load, just to restart in OS 9. It would speed things up a little bit if I could just boot right into 9 from the beginning.
