Hey everyone,

I have a Lenovo Y570 with Intel Core i7 2630QM(2.00GHz) 15.6" 8GB Memory DDR3 1333 750GB HDD 5400rpm BD Combo NVIDIA GeForce GT 555M.

I was able to install Mountain Lion 10.8 by booting with -x busratio=20.

However, once i get to the set up screen where you pick your country the mouse and keyboard do not work. They worked to install lion. If anyone has any tips or know how i can fix this i would greatly appreciate it.
 
How did you manage to get Mountain Lion installed? Did you start with Snow Leopard and then upgrade. I bought snow leopard and I have the same laptop but I can't get it to boot on Snow Leopard, I get a kernel panic error.
