ZIP archive of about 2.83 MB with BIOS firmware for the OSAMU2-BT-HPC-MV-MB-V1 mainboard, version V1 per the name. The name does not state whether an EC image is included, so open the archive and check its contents before planning a repair. Such dumps are used to revive boards with a corrupted SPI flash, programmed with a CH341A or similar tool. Read and save the original chip first, confirm the board marking on the PCB, and check that the file length equals the chip size.
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.
