hi , this is the original

the posted bios is almost empty as @peste said. What programmer are you using ? .let me guess, a CH341A ? ,with a clip ? .Whatever bios programmer it is you need to make sure you can use it first before flashing another bios,you need to make good backups .

I guessed wrong then .I don`t know what the 25X40CL is for maybe the EC ? .Try this EC cut from the bios update. Use the bios posted by @peste

P12.A1 - BIOS (ODD SKU)
P11.B0 - BIOS (Non-ODD SKU)

Edit: U9 is the external IT8528 512K ROM
