Original BIOS read from an HP G4 laptop whose board is identified in the name as DA0R53MB6E0, a number in the Quanta DA0 style, with an OK tag suggesting a known working dump. The raw binary is 4.00 MB, sized for a 32 Mbit SPI flash device. A technician would write this to the BIOS chip with a programmer to revive a board stuck on no display or boot loop. Check the PCB marking and revision against the name, and back up your own chip before writing, since serial and system data differ per unit.
