Tried that and it shows the happy mac, then goes to a floppy question mark. sits there, then puts the happy mac over the floppy disk icon. and it just sits. i left it for an hour or so.
I did manage to make sure the OS 9 drivers are on the drive(leopard still has that option for some reason). But I had the image of my 9.1 disk restored using my intel mac, so i think it was formatted to the GUID instead of the older format.
EDIT. FUDGE!!!!!! Forgot to add OS 9 drivers to the whole external drive, which has a back up of a lot of my files. I will check back once I get this sorted out.
