modding dell bios

hello, my name is david I am french .
I have a problem, I have a dell optiplex 745 , I put 8 GB of RAM and I put a core 2 duo E7500 but he doesn’t work on this motherboard because there isn’t the microcode of this cpu in the bios.
I searched and used lots of programs but none work for mod the bios.
Do anyone know how to mod a dell bios in .exe ?

my bios is heiden2.6.6 on the dell site

thanks you for help me

@ ksoul:
Welcome at Win-RAID Forum!

I cannot help you, because I am not an expert reharding the modification of a Dell BIOS.
If you shouldn’t get support by any other Forum member, I recommend to ask >here< for amodded BIOS.
