Bios Mods -The Best BIOS Update and Modification Source

Hello,

Firstly, let me say if someone can assist me with this problem I'm willing to pay/donate.

I'll try to keep it short...

We have an Asrock Fatal1ty X99M motherboard with 2x 1.00 BIOS chips, but to support the CPU we have we need 3.1 or greater. Of course we couldn't upgrade the BIOS as the computer would not even POST.
I purchased an updated BIOS chip off ebay, that got it working but on every boot it gives the error about the MAC address being wrong. We can go past this and the computer runs fine..it seems.

But we really need to get rid of this error. I have purchased a CH341A programmer to maybe fix this but it aint easy!

Either I need to copy the MAC off one of the original 1.00 BIOS chips and copy/rewrite the MAC address to the new 3.1 BIOS chip.

Or maybe download the latest BIOS from the asrock site and rewrite to one of the original 1.00 chips that should hold the MAC address...?

Any help is appreciated. I sometimes enjoy the challenge of figuring these things out myself but I think I'm ready just to get someone who has been through this kind of thing to help me with it.

Thanks!!

No-one has offered help but there have been quite a few views. Does this mean it's a really difficult thing to do and no-one can help? Or just no-one wants to help? I need to know whether to persist with fixing this BIOS chip or look at other alternatives.... anyone...?
