BIOS archive for board NB5979 MB V10, containing both 4MB and 8MB images according to the name. No laptop brand or model is specified, so identify the device from the PCB markings before use. Having two sizes suggests separate images for different flash chips or split BIOS and EC regions; check the chip capacity on the board to pick the right file. Always dump and keep the original SPI contents with a programmer before writing anything to the chip.
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.
