Re: lost mac address in hp 8300

Hi friends, for my part, I couldn't find my mac address, so I used that of an old Wi-Fi card. for this I therefore used UefiTool to locate the mac address (FF FF FF FF FF FF ) in the new downloaded bios, then I wrote
the mac address of the old wifi card manually In the New BIOS instead of ( FF FF FF FF FF FF ), after finishing writing I save everything under a new name ( ex: Moded.bin ).
I unsolder the BIOS memory chip from the motherboard, I make a backup of the chip (using ch341a programmer) with the same programmer I flash the chip with the new BIOS (Moded.bin), then I reassemble the everything and it works
