I tried it, could not get it to boot the DVD, it is really picky. Best to have a pure Intel.

Use the manual leopard to snow leopard method I believe is the best choice for 'Legacy' systems, because you can customize your own DVD, you would edit, the dmg using DiskUtility good feature to burn your own DVD having pre-made kexts and patches. this way you can still keep leopard running and do tests for Snow Leopard.

I ran across a guide which I have here on this pc, it is very good.

I haven't tried it yet.

The other is EmpireEFIamd with sb600 support.iso .. burn this to a CD and the use that to install Retail DVD. Then once up you can hunt around for proper kexts.

If you know how to inject into PCEFI 10.x then copy this to another boot file into your pre-made DVD of snow.

happy new year
