Firmware image of 8 MB named only after the 4740s model, a number that fits the HP ProBook s-series naming, although the name states no brand. The (2) suffix marks it as a second copy, perhaps a different read of the same machine. No board number, revision or BIOS version appears in the name, so confirm the platform before use. The 8 MB size suits a 64 Mbit SPI flash. Read and save the original chip with a programmer such as a CH341A first, then compare both files before writing.
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.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
