Go to HP website and download the bios update from there. Open the .exe with 7-zip or other tool that can open compressed install files and extract things. Inside is a ROM.CAB file, and inside that file (open with 7-zip or equivalent) is the rom.bin file together with some signature files.

Hope that helps, have NOT tested this myself and it might be in some odd format.

Here is the uncompressed version of the BIOS. It's 16,321KB, not 8mb, so I don't know if that will help you or not. Version F.01.

Thanks but the bin file at the website is not a full image but an update. What I need is the full bin dump from the SPI EEPROM of a working motherboard which is 8MB in size [Windbond 25Q64FVSIG] to repair the corrupted bios on the Probook 4540s.It does not respond to bios recovery procedures. I normally make bios backups of Laptops that come to me for repairs for situations like this. So if anyone will be kind enough to make a copy from a working machine, I will be very grateful. I also have some backups of other models available.
