Re: M900 BIOS reset

I seem to have exact same issue on my M900, after BIOS update have black screen and PC is not booting OS.


I have tried to change the jumper from original 4/6 pin to 2/4 and doesn't help - does not boot.


On your pic you have the jumper 2/1 - am I doing something wrong?


The only thing is I have no external DVD and trying to boot from USB (created FreeDos USB using Rufus and copied all iso content into root folder).
