Compressed RAR archive with firmware for a mainboard marked NB8513 MB in version or revision V3, at 5.52 MB packed. The name gives no brand, chip type or BIOS version, so open the archive and inspect the image sizes before use. Such files are normally flashed to the SPI BIOS chip with an external programmer to revive a dead or bricked board. Match the NB8513 marking and V3 revision printed on the PCB, and save a read of the existing chip before overwriting it.
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.
