I'm using a 20" white intel iMac and cannot manage to remove a linux boot disc from the optical drive. At first, the only way that i managed to boot to the linux disc in the first place was from the Startup Disk menu in OSX. I could not even get to the Startup Manager ('opt' at boot) or boot straight to the disc ('C'). Now i'm in a position where no matter what i do, the system boots to the linux disc. I cannot even force the startup into OSX to try to eject the disc from there. I've tried holding all of these keys/combinations at startup: eject mouse button f12 d x cmd-x cmd-opt-p-r (in hopes of resetting the startup disc in the EFI, but i don't ever hear the two beeps that i think i'm supposed to) cmd-opt-n-v t (i can't even boot as a target disc!) I've also tried to see if the disc tries to eject but the piece of metal that closes off the slot never even tries to get out of the way to prepare the disc for ejection. Any other ideas?
