dell inspiron 620 bios mod for ivy bridge support

hey all, was wondering if some wizard might be willing to mod some ivybridge micro code into the dell inspiron 620 a10 bios. everything i read says dell never added it. and i got a coworker with a 10 year old that wants a gaming pc. i got an ivy bridge i5.... and that [censored] inspiron 620 with a pentium cpu. and if im completely ignorant will someone explain to me if this is not possible why?

thank you
