Thanks for your reply, appreciate it.

However, as I mentioned I have tried and failed to patch my ISO from Windows with Transmac, MagicISO and ISOBuster. Is it really just a case of copying and pasting kext into system/library/extensions?

What I have is a .kext file for my chipset which appears as a folder on my windows desktop, is this what needs to be pasted?

-Any ideas why these ISO programs wouldn’t be allowing me to make the change? Is it because it’s a .kext file and not a ppf? If someone could clear that up for me I’d be made up!
