Force osx or os9 to startup

[Steve keen]

I have a beige G3 tower which has two 4 gig hard drives installed, i have installed OS10.2 on the ultra scsi drive address 0, and OS9 on ultra scsi drive given the address 2, i have formated both apple drives using the aproprate disk utilities in 10.2 and os9.
The problem i am having is after installing os9 and using it installed on drive 2 i then want to use os10 i select it in the startup control panel and it starts up in 10 fine.
When i want to start up in os9 even thought i have selected os9 has the start up system, it begins to load os9 but resets the mac and then starts up in os10.2 .
i have reset the pram and rebuilt the desktop in os9.
both systems are clean installs.
If i disconect the drive with 10.2 installed the mac will load fine in os9.

Question?
Is there something i have done wrong that prevents me from using two drives with diffrent systems on each.
is there a keyboard shortcut to force it to start up in os9 or 10.
Why is the mac restarting when os9 begins to load, it just shows the smiling classic computer the resets, then proceeds to load 10.

any ideas would be gratfully received

Hi Steve. I'm not sure.

For newer machines you press the Option Key at Startup.

You get a chice what to Boot from. Don't thing the Beige allows this.

Is it Fragmented?

Sounds a little like a problem I once had with my partitioned Wallstreet drive. It wouldn't go from X to 9 without starting up into an 8.6 partition first. Then I could go from 8.6 to 9. Really weird. Fixed it by initializing, repartitioning and reinstalling.

Anyway, you could try to use Command+Option+Shift+Delete+2 to force it to try to start up from the OS 9 drive on startup/restart.

Thanks guys,
Found the articals on the G3 very usefull, anyway i finally got over the problem by installing OS 9.21 instead of OS9, this cured the problem,i'm now able to select the drives and differrrent operating systems at will and find they load with no reset problems.
again thanks for your help
