An 8 MB raw BIOS binary labelled for the HP 4540, most likely a ProBook 4540s, with the name marking it as checked and working. No board number or BIOS version is stated. A full dump of this size needs an 8 MB (64 Mbit) SPI flash chip and is written with an external programmer. Since it comes from another machine, serial number and system data may need correcting afterward, and the original chip should always be backed up before flashing.
