You are completly right. The disk selector is a little app which is located in your Firmware. Only Macs with the NEW Firmware structure (I believe most iMacs, and every G4, maybe even more machines) have this little app. And it is real handy.Originally posted by mtc7501
I'm suspecting that since I have OS X on a BW G3, and a 7500 it's because it's not supported on those machines. On my New Firewire Powerbook though, without OS X, I get a nice little startup disk selecter.
