Background: My laptop crashed an was completely dead. I searched a schematic and changed two components related to the power circuit. Now the laptop shows 2 red and 1 blue blink code at least.
People reported a corrupt bios could be the cause so I created a bios dump using flashrom.
Could you please take a look if it looks correct? That would be great! 
I have no idea how bios files should look like in hex editor.
How can I get started with bios hex editing?
