Firmware dump for a Dell laptop with regulatory model PP04X, board DAJM7BMB8F0 revision F, in a 907 KB RAR archive. The DA0-style board number follows Quanta's scheme, so the mainboard was made by Quanta for Dell. Use the image to reprogram the BIOS flash with an external programmer on a dead or non-booting unit. Make sure the board number and the rev F marking on your PCB match, back up the original chip, and confirm the image size fits the flash part before writing.
