BIOS firmware for the HP Pavilion 15-g025sr, product code G2A86EA, compressed into a 2.45 MB RAR; the board number is not stated, so identify the motherboard model printed on the PCB before using it. Such a dump is written to the SPI flash with a programmer like a CH341A to revive a board that has no image or fails after a bad update. Always save the current chip contents first, extract the archive to check what it contains, and make sure the binary size corresponds to the installed flash capacity.
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.
