[REQUEST] Add AHCI option to mod bios for Dell Inspiron 6400

Hi!

I have a Dell Inspiron 6400, his bios don't have AHCI option.

The latest official bios is here:

I tried open the MM061A17.rom with Phoenix Editor (BIOSEdit2.2.13 Beta1) but it returns "No BCPs found!"

I know in Dell Inspiron 1525 has the AHCI option, but i cant open the .rom file either (i'm absolutely newbie modifying bios...)

My SATA controller is:
00:1f.2 IDE interface: Intel Corporation 82801GBM/GHM (ICH7-M Family) SATA Controller [IDE mode] (rev 01)

My idea is extract the option and possibly the driver included in inspiron 1525 and copy them for inspiron 6400, but i dont know if is it possible...

Can anybody help me?

Thank you very much
