Main BIOS for the HP dm3 laptop, listed for boards 41-AB4300-D00G and 41-AB4310-C00G, in a 998 KB RAR archive. The name gives a 2MB size, pointing to a 2 MB (16 Mbit) SPI flash chip. A companion package with a GPU code exists for the same boards, so pick the right file for the chip you are servicing. Write the image with a programmer to revive a board that powers on with no display. Confirm the printed board number, check the chip capacity, and back up the original 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 @biosarchive. Enginerys does not host this file.
