[Guide] Integration of AMD's AHCI/RAID drivers into a WinXP/W2k3 CD

Hello Dieter,
I have the same hardware ID as @noname1 (DEV_43EB) and I would like to know if doing modifications to the driver’s hex is hard or not and if it is possible to tell me, how can I do it.
Don’t worry, I will not share the driver if I modify it and will keep it to myself to avoid any Copyright violation.
Also, I don’t know where I can find a valid 32 bits driver since the driver used is Microsoft’s.

Thanks in advance for your answer
