svitale75 how big do you make the 2 partitions "install" and "os"? I assume OS has to be bigger if your going to run SL as your main OS. Other guides talk about DSDT.aml being edited and also editing the com.apple.boot file and smbios.plist file in order to get everything working right. I have a P5K pro and if I follow your guide will everything work? I've been doing other procedures like DSDT patches and editting smbios.plist and always get kernel panics.
