So apparently you should be able to update the boot camp drivers by putting the Leopard disk in while booted into windows. This doesn't seem to do anything, though. I've tried searching the disk too. Am I missing something?
Aha, I found the answer. I use the program called macdrive 7 to read and write to my HFS+ partitions and there's an option to allow you to either view mac files or windows files off your dvd drive. It was set to 'view mac files,' so that's why I wasn't seeing the .exe. Thanks anyways for the help.
