I think I might have cracked my own problem; enabling me to install OS 9.2.2 without my original cube CPU, and without installing on another computer:

1. re-install Mac OS 10.4 (Currently OS 10.5 is installed)

2. Install OS 9 in Classic mode (or whatever it's called)

3. Install Toast 4 in OS 9, enabling me to cook a custom, bootable OS 9.2.2 install cd-rom *without* the Apple CPU enabler

4. Install OS 9 as per usual

Will let you all know how it goes.

Cheers,
