Is there any board specific information such as MAC addresses or serial numbers in the BIOS as flashed from the factory? I’ve bricked mine and need to reflash directly and was curious if any such data was stored within that I should look for and retain first.
Board-specific information?
I do think that MAC is not in BIOS, but inside Ethernet chip.
Serial number of the board? Don’t think it’s somewhere in write area of the BIOS.
Before reflash, what symptoms do you have? If USB is working it should be possible to just reset BIOS without reflashing
I made a bad setting in the BIOS and it doesn’t boot at all now.
If usb is working you need to enter bios in blind (press delete on startup for like 10-20 secs), than click F5 i believe, there is screenshot on wiki with shortcuts
