BIOS firmware labelled HP 4200S, most likely the ProBook 4200s series, as a 2.00 MB binary that suits a 16 Mbit SPI flash chip. The name does not state a board number, revision or version, so compatibility must be confirmed from the motherboard markings. Images like this are written with an external programmer to recover a board that does not boot. Read and archive the original chip first, and check that the chip capacity matches the file size.
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.
