BIOS image for an NPB-marked motherboard labelled N81, version C, in a compact 311 KB RAR archive. No device brand or model is given, so identification depends on matching the N81 and VER C markings printed on the board. Files like this are flashed to the SPI chip with a hardware programmer when a unit is dead, stuck on logo or showing no display. Read and store the original chip first, and make sure the extracted image size matches the chip capacity, otherwise it will not write correctly.
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.
