Hi @lfb6 ,
So at the end i have used the corrected bios region and replaced in my working dump as you wrote.
Flashed but did not boot again. tried with charger/without cmos batt remove etc. but nothing apart keyboard light
Flashed the dump i used to replace the corrected bios and it booted after few try. Cmos unplug charger plug, unplug battery unplug etc. but it did boot.
So for now i will stay like that unless we figure out what the heck is wrong and i build my pogo-pin adapter 
to flash without soldering.
But huge thank you for all your help @lfb6
Thank you
Kind regards
Norberto
Sorry to hear that, but thanks a lot for the feedback 
For the moment I don’t have any good idea. There are different reports where transplanting the DVAR back into stock bios worked, but there’s little to find regarding DVAR structure 
Hi Norberto,
I have the exact same issue as you. Would it be possible you describe in a deeper way what you did? I have never done any BIOS Modding but like to fix things. If you have time/would like to help a brother out I’d love to learn something from your experience. If you also want we can write in spanish via PM.
Muchas gracias,
Miguel
