Firmware for an AMD-platform HP 15 laptop, labelled china, stored as a 4.00 MB file with no extension and no board number in its name. The size points to a 32 Mbit SPI flash chip. Technicians write such raw dumps with an external programmer to revive a board stuck with corrupted BIOS, no display or a boot loop. Since the motherboard identity is not stated, check the PCB silkscreen and the chip marking, confirm capacity matches exactly, and read out the original contents before writing this image.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosfilebins. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
