panic error asus x43sj

Hi guys,
Maybe someone could help me. I tried to set up Snow leopard original purchased disc.

My config:
-asus x43sj
-intel core I3
-2,1ghz

I started with the tonymacx86 iboot, then with the snow leopard disk. Everything was fine until I install multibeast.
Updated snow leopard first then I started Multibeast 3.7.2.
Now can't boot on snow leopard.
Some one can help me it will be really appreciated.
Thanks

You must use the RETAIL version of SL, because retail disc is generic and will install on any Mac made before it was released (assuming installation requirements are met). On OEM discs the installer is generally locked to the hardware it shipped with.
