Bios Mods -The Best BIOS Update and Modification Source

Hello,

i wanted to ask, if it is possible to upgrade the BIOS of my Fujitsu Lifebook NH751 running with a Sandy Bridge "Mobile DualCore Intel Core i7-2640M, 3000 MHz (30 x 100)" so that is is possible to upgrade to a Ivy Bridge "i7-3520M" ore any other I7 from the Ivy Bridge series.
The reason for this is, that i want to use PCIE 3.0 which came out with this processor familly.
I contacted Fujitsu support, but they where not able to tell me, if a Sandy Bridge Processor would be compatible with my mainboard. The only thing, they mentioned, is that i possibly have to use a modified BIOS. 
Physically the processors fit into the socket, because it was not changed for Ivy Bridhe an the i7-3520M has 35 W too, but i don't kmow if it will work with the intel Chipset.

The last Bios available from Fujitsu is "1.20 (05.07.2012)"

You laptop is based on HM65 chipset. It doesn't support CPU with Ivy Bridge core.
