BIOS and EC firmware package for a board marked NH4ST0X, revision 1.0, compressed into a 4.39 MB RAR archive. The name labels the dump as working and fully tested. The name gives no brand or chip details, so open the archive to see which images it holds for the BIOS flash and the embedded controller. These images are normally written with an SPI programmer such as a CH341A clip. Read and save the original chip contents first, and confirm that the image size matches the capacity of the flash chip on the board.
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.
