Resolution change and update

[bassiebal]

Ok I finnaly was able to install mac os on my pc using the Lawless ppc 10.5.4.

(according to a hcl somewhere that was the only option for my mobo )

 

My question is how do i update it to snow leopard or just update it.

and how do I change resolution ( i am stuck at a very low one )

 

My specs:

 

Graka: Sapphire Radeon ati HD 4850 dual dvi 512mb

Mobo: Ga-ma78gm-s2h

Proccesor: Amd x3

 

Thanks
