AMD X2 + A8N SLi premiun

I reacently got an AMD X2 +3800 and an ASUS A8N SLi Premiun... now, when I read the manual for the mobo it didnt had anythig about the X2... I already know that to make it work I need to update the BIOS.... now... to update it I need to place a prossesor in the socket... can it be the same X2, or I will have to use another... can using the X2 damage the mobo or the prossesor itself?

my sound stupid, but I dont want to break them...

You shouldn't have to update the BIOS at all as long as the mobo is the same socket as the CPU.
