Sorry you've had this experience, it's sad people don't help each other enough. I believe it's because they were treated the same when they first got into the scene. They think they had to search and learn the hard way so you can too. Unfortunately the people with real knowledge that stick around and share are few and far between.
Imho the majority of noobs don't help themselves though, asking for help when spending 5 mins searching would reveal the answer. Most of the time, working it out for yourself is the best way to learn, rather than getting step by step instructions but no understanding. Reading, research and knowing your hardware is the key to OSx86.
Back to your unanswered question, OS X has hidden files just like windows. To show them you enter this in terminal:
Code:
defaults write com.apple.Finder AppleShowAllFiles TRUE
killall Finder
You can then find all the drivers on the install dvd in /System/Installation/Packages/
If you need to get kexts out of pkg files you can use
Pacifist
To hide the files again:
Code:
defaults write com.apple.Finder AppleShowAllFiles FALSE
killall Finder
To install kexts and do a hell of a lot more, it's best you get yourself a copy of the swiss army knife of OSx86 -
OSx86Tools. You might also be able to get your GFX card working with an EFI string which you can create with OSx86Tools. This app will save you having to get your hands dirty in terminal.
