Extra copy of a 4.00 MB BIOS file for the HP ProBook 6550b notebook. The name carries no motherboard number, revision or firmware version. It matches a 32 Mbit SPI flash and can be opened in a hex editor for checking or written with an external programmer during board repair. Since several 6550b dumps are listed, compare them to choose the intended one. Read and store the original chip contents before erasing and confirm the target board is the same model.
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.
