BIOS dump for an HP 15s notebook built on Quanta board DA0P5HMB8I0, revision I, labelled as working. The 16 MB size corresponds to a 128 Mbit SPI flash chip. DA0-prefixed numbers are Quanta's motherboard codes, printed on the PCB silkscreen near the board edge, so compare that number and the revision letter before flashing. Technicians write such images with an external programmer to recover boards that fail to power on or display, and should keep a copy of the original chip contents first.
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 @bios_laptopomi. 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 →
