BIOS .zip 3.63 MB Shared

Fixed BIOS image for the HP 4540s, zipped to 3.63 MB, with the name pointing to a single repaired binary inside. Fixed dumps usually have corrupted regions or settings corrected so the board can start again, but the exact changes are not described. Write it to the SPI flash with an external programmer after reading and saving the original chip. Confirm the motherboard revision and the flash chip capacity match the image, and expect to reprogram serial or system data afterwards if the dump is generic.
