I just sold my iMac G4. I was wiping the HD with my Tiger Up-To-Date Disk and it never ejected. Now, I can't get it out, and it's trying to do a network startup. I plugged it in to the network but it came up with nothing. I even tried zapping the PRAM and got nothing. I'm getting the flashing folder with question mark icon. And my disk is still in the computer. WHAT DO I DO? It's got to ship TOMORROW.
