HP 15 firmware dump tagged green P, 4 MB in size, without board number, revision or BIOS version. The labels likely distinguish one board variant from similar HP 15 models, but their meaning is not stated. A full chip image like this is written to a 32 Mbit SPI flash with a programmer during no-boot repairs. Because identification is loose, compare PCB markings with the source, confirm the chip size matches, and read and keep the original contents before writing anything.
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 →
