i have some other question:

- which is the best way to backup my current installation and restore it if i have a problem?
can i clone my hdd and restore it?which program i have to use?

- i can run snow leo only in 32 bit, if i try to run with x86_64 i have a kernel panic,can i solve this?there's a real difference between run leo in 32 or 64 bit mode?my pc was recognized as macmini 2,1, can be the cause of that?
