BIOS firmware package for an HP board identified only by the internal designation OSAMU2_CR_HPC MV_MB_V1, stored as a 3.60 MB ZIP archive. The name gives no laptop model or ODM board number, so the archive contents should be inspected to see whether it holds a full SPI dump or a vendor update image. Before programming anything, read and save the original flash chip with a programmer such as a CH341A, compare the chip capacity against the image size, and confirm the marking on the PCB matches the Osamu designation.
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 @biosarchive. Enginerys does not host this file.
