BIOS firmware for a board labelled NB2372_MB_V6, with the name noting an 8 MB BIOS, packed in a RAR archive. The brand and model are not given, so identify the device by the board number printed on the PCB. The 8 MB figure indicates the image targets a 64 Mbit SPI flash chip, which you should confirm on the chip marking before writing. Use an external programmer to flash it, and always read and back up the original chip contents first so the original data can be restored if needed.
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.
