I'm completely new to this. I've just installed the Bitcoin wallet and GuiMiner, followed the instructions on the website, but I keep getting the message: "Kernel errow: Gpu not supported! Phatk2 is designed for ATI 5xxx and new only. Try -k poclbm instead."
Now I've already read 1 post and it does give an answer to this, but I have no idea how to implement or even where to begin. Sorry for my ignorance. Any and all help and advice welcome.
