HP 15 notebook BIOS in a 2.02 MB RAR archive for the Quanta DAY21AMB6D0 mainboard, revision D. The archive probably contains a raw image for flashing the SPI chip with an external programmer when recovering a dead or corrupted board. Quanta DA-coded boards cover many HP models, so match both the board number and revision letter on the PCB. After extracting, confirm the image size matches the flash capacity, and back up the original contents before writing.
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 @biosarchive. Enginerys does not host this file.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
