My customer has an iMac G5 (not sure if Power PC or intel chip). It does not boot so maybe bad HW or corrupt OS. To find out I insert OS X 10.4 CD that came with it and startup holding D key down. This start Apple Hardware Test (AHT) which will tells me if bad HW and what kind of HW is bad.
My question is how do I eject 10.4 CD as system can not boot so I cannot simply drag CD icon on desktop to trash. ie. I need to use just keyboard and mouse to do it I think. Please reply with 1 or 2 things to try.
