Zip archive of BIOS firmware for the HP 255 G1 laptop, about 4.4 MB compressed. The name gives no board number, revision or version, so open the archive to see whether it holds a raw chip dump, an EC image or a vendor update package. Before programming, identify the motherboard number printed on the PCB and confirm it matches the source of the dump. Back up the original SPI flash with your programmer first and verify the image size equals the chip 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 @biosfilebins. Enginerys does not host this file.
