I just bought a new i3 3220 cpu, and I understand that I need to update the mobo's bios because my current bios only support pentium g630. But when I try to update the bios to ivy bridge, it says driver not found or something like that(I forgot). Simply, I cannot update it to ivy bridge eventhough my mobo support ivy bridge. Why is that? Need help ASAP. And my mobo use manual update as there's no ezflash.

My mobo is :
Acer veriton m2610g

Cpu from pentium g630 to i3 3220 3rd gen.
