BIOS dump for a board labelled NB6380C-MB-V3, stored in a 9.40 MB RAR archive and tagged as an old version. No brand or laptop model is given in the name, so identify the device from the board silkscreen before use. The archive should contain an image for the SPI flash chip; check that its size equals the chip capacity. Save a backup of the existing chip with a programmer first, and keep in mind an older firmware may differ from what the board originally shipped with.
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 @schematiclaptopramkushwaha. Enginerys does not host this file.
