They are not pin-compatible in firmware terms.
Search near the core chipset or the multi-IO (Super I/O) controller.
For example, one relevant SoftPaq for this model was SP78256.exe , which corresponds to BIOS version 01.06. When you run such an official SoftPaq, it creates a directory (often at C:\SWSETUP\ ) where you will find the necessary files. It is crucial to understand that a .bin file intended for an external USB recovery drive must be placed in a specific folder structure on the USB drive to be recognized: Hewlett-Packard\BIOS\New . hp probook 640 g2 bios bin file

An SOP8 test clip allows you to read and write to the chip while it remains on the board. If the clip fails to make solid contact due to circuit interference, you must desolder the chip and place it in an external socket.

However, the .bin files found in official SoftPaqs are often the complete firmware image. They are typically the "BIOS region" only, lacking other critical parts of the SPI flash chip, such as the Intel Management Engine (ME) region and the Flash Descriptor . This is a major source of confusion. As one user on the Win-Raid forum noted, after extracting official HP BIOS files like N76_0133.bin and N87_0133.bin , they observed that "Neither contain ME Firmware". This is why a direct BIOS update file will not work for external programming and why you need a complete .bin full dump for such procedures.
