BIOS image for the OSAMU2 SHB HPC MV mainboard version V1, delivered as a 3.52 MB RAR archive. OSAMU2 is a platform code name and HPC hints at an HP-related design, though the name names no laptop model. Such a dump is written to the SPI chip with an external programmer to recover a board that does not boot or has a damaged firmware. Confirm that your PCB silkscreen reads the same platform and version, read the existing chip first as a backup, and make sure the file size fits the chip.
