OS 10.4 / 9.2.2 Startup Conundrum

[David]

Can anyone explain why my G4 (AGP Graphics 400 MHz) refuses to start up when I have both an OS X (10.4) and an OS 9.2.2 drive installed?

It starts up from each drive when they are installed individually and DiskWarrior verifies both drives are OK.

If I hold the option key during startup with both drives installed I get the arrows of the OS X drive-select screen but without the drive buttons - so I guess there is some basic recognition of an OS X drive presence.

Neither drive shows when I boot from the DW CD.

Also, I've switched between the options of master/slave jumper settings.

Many thanks in advance for any advice.

Regards to all

First, have you run the firmware update on that Mac?

How large are the drives? It will only take 128G and smaller natively.

Are you sure you have the Master/Slave jumpers correct?

THANK YOU KRIS!!!!

Sorry I've taken so long to respond to you suggestions.

The GOOD NEWS is that everything is up and running 100%.

The BAD NEWS is that I haven't the vaguest clue as to which of your links gave me the solution to the problem.

I swapped drives in, out and back and forth;
I changed jumper settings here, there and everywhere,
I downloaded and up-graded this, that and t'other;
I cursed, cussed and swore;
I checked firmware, PRAM and CUDA;
I sulked, cried and pleaded;

All the above were in random order over several days until Saturday morning when, in sheer desperation;
I crossed my fingers, pushed the power button and held the option key.

BINGO - IT WORKS!!!!!!

And, it's been working just fine ever since.
I just wish I could remember what I did Friday night****

Thank you

**** It might have been a Single Malt Solution

It was probably the cursing, crying and pleading.  

Or the fingers crossed...

Then again, maybe it was the malt....  

Glad it is running OK.
