i just got a powermac g4 last week, and the computer is awesome. It was running Mac OS 9.2, so i bought the Mac OS X Panther software. The problem is that i cant open up my disc drives to install it, because i have a windows keyboard. I know that on the mac keyboards, they have a button to open the drives, but my keyboard cant. can someone please tell me how to open the drives from within the computer? I've opened software that has eject buttons for DVD and CD players but it says no disc present sop i cant open them. please help me!!!!
