Hi i would like some help installing OSX SL on my laptop.. Its running an Intel i3, 4gigs of ddr3, and a ATi Radeon 5650, which i have found the kext for.. but what do i do now, and what do i need, and finally how do i use it??

I also have a brand new "desktop" that i would like OSX SL on if its possible.
its an Asrock E350M1 board with an AMD Zacate onboard, and a ATi Radeon 6130 graphichs card onboard, 4gigs of ddr3..

whell, if you have osx already installed just get the app "kext helper" or "kext utility" and use that to install the kext
