Bios mod to use a dell e6530 internal keyboard on a dell e6430 ?

Hello,

As I have some pieces of a dell e6430 available (without frame), I wanted to use an internal keyboard e6530 on it, in order to keep usb ports available for other things and have a comfortable keyboard with real numpad.

It works very well except the numpad (as I thought) that reacts as the e6430 keyboard (but special keys added on the e6530 are working ?)

I didn’t see a clearly defined module for the keyboard that I could take from the e6530 bios to the e6430, where do you think I have to search in the bioses to have the real numpad fully working ?

Thanks in advance for the answers.
