Ivy Bridge support for Lenovo Thinkcentre M71e

[Lolucoca]

Hi! Long time user, first time poster here. I've got a slight problem. I've got a ThinkCentre M71e that I'm planning to upgrade to an i5 3470 but it doesn't officially support Ivy Bridge processors. It's an H61 Chipset so it should technically support Ivy Bridge processors, right?
I'm pretty good at soldering and I do have a bunch of spare parts available. I've attached both the BIOS the board is using right now as well as the BIOS of an Intel DH61WW motherboard which also uses the same chipset and looks (vaguely) similar. Latter of which *does* support Ivy Bridge processors. As of now, the board doesn't display anything on the screen and it turns on and off in regular intervals when I install the i5. Other than that it doesn't do an awful lot. No beeps either. The spec code of the i5 is SR0T8. Thanks a lot!

Sure thing! There you go!
[Edit: Didn't know which one you meant so I added screenshots of the Intel board and i5 as well]

You need to flash BIOS from ThinkCentre M72e.
U926 & U927 chips

There is no U927 on the M71e motherboard, it one only has one 4MB flash chip.

So you need to find 8MB flash chip.

I've got 8MB flash chips on hand, that's not a problem. The flash utility Lenovo gives you has these weird .CAP files and I'm not sure if they've done some trickery with the BIOS itself. ASRock does a similar thing but their BIOSes just start at address 0x1000.

You need to find BIOS dump from ThinkCentre M72e, both chips.
And I'll combine it to one 8MB file.

Confusingly, the ThinkCentre M72e BIOS is only 4MB in size. I've used UEFITools to extract the image. I'm not that familiar with playing around with BIOSes, does that look like a BIOS to you? As in something that could possibly work?

It's not real dump.
I've found one dump by myself.
Try to flash this mod to 8MB flash chip and solder it.
