I'm trying to install an airport extreme card in my G3 iBook. I think I'm following the installation instructions exactly, but everytime I go to turn the computer back on, I get nothing. When I take the card out, the computer turns on just fine. Obviously I don't have the card installed right. I've looked all over the apple site for help, but none of the documents help. I'm beginning to think that the G3 iBook can't take an airport extreme card. The card doesn't seem to fit into the slot like it's pictured. Can anyone give me any insight into my installation problems? Is it a "technique" problem with how I'm putting the card in, or is it simply that this is the wrong card for this computer?
