HP ProBook 4540s system ROM in its Core i7 configuration, using BIOS family 68IRR at version F.42, provided as a 5.00 MB .rom file. The 68IRR code is HP's BIOS family identifier shared by related models, while F.42 is the firmware release. The odd size suggests the region layout differs from a full chip image, so check how it maps to your SPI flash before programming. Back up the original chip first, since HP stores serial and product data in the flash.

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