Arch Linux

Hi,
I am new to the forum so asking this question here.  I have been trying to install on my early 2006 Macbook pro with Intel Cor Duo (not Core2Duo). I succeeded in booting from USB by booting through Pop blot boot cd.  but the problem is the MBP stays on first boot splash screen and neither the keyboard or mouse pad work. I tried till now installing rEFInd without success.  Is there a way out to this problem or someone can suggest some other booting method.  Help would be highly appreciated.Thanks
