Firmware archive labelled OSAMU2 with DIS, KB, HPC, PV and MB V1 tokens, 2.35 MB in ZIP form. OSAMU2 looks like a project code name; DIS commonly means discrete graphics, PV usually indicates a production-validation build, and MB V1 suggests main board version 1. KB may refer to keyboard or EC firmware, but the name does not confirm it. Open the archive and identify each image before use. Match the board code on the PCB, back up the original SPI chip and check the file length against its capacity.
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 @bios_laptop. Enginerys does not host this file.
