BIOS package for the Noblex NB16W101 notebook, whose mainboard is labelled M300B MAIN PCB, stored as a 19.3 MB RAR archive. The larger size suggests the archive may hold more than a single dump, so inspect the contents and pick the file matching your flash chip capacity. Technicians use such images to reprogram the SPI chip with a programmer when the machine stays dead or loops at startup. Save a copy of the original chip before writing and confirm the board marking matches M300B.
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.
