BIOS image for the HP ProBook 6550b business laptop, 4.00 MB in size. No board number, revision or firmware version is given in the name. The capacity matches a 32 Mbit SPI flash, which can be rewritten with an external programmer to recover a unit with corrupted firmware or a failed update. Several similar 6550b files exist, so comparing them helps pick a clean one. Back up the existing chip before erasing and verify the written content against the file afterwards.
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.
