Hi guys! Yes, I did a search. And yes, I know there is a similar thread just a little bit down. But I have done EVERYTHING I have read, and nothing has worked. I've done a complete reinstall. I've downloaded the x64 drivers. I've tried everything, and yet my function keys (sound, brightness, eject key, etc) just won't work!! Does anyone have any other ideas? They did work when I just used the original disc that came with my MBP. They all worked except the eject key when I only used said Leopard disc. So, when I tried the x64 disc, everything went kaput, including my sound. I have since got that working, but now neither my function keys, or eject key, are working. Can someone give me a step-by-step of what they might have done to get around this, with links? Pretty please? Thank you.
