I was able to borrow a version of Leopard and that seems to be booting on the Atom MB... IF this works, I still have a speed bump... If I upgrade with the SL copy I bought, I think it may hang after it reboots....
I think I need to make a new SL DVD copy with the hacked 10.6.2 kernel that enables the Atom proc again and also is designed for a 64bit proc (this Atom is) and dual core.
So far, the borrowed version is working.. I finally got to the first screen.
