Zipped BIOS dump of 7.41 MB whose name suggests an unlocked or password-removed image, though no device, brand or board number is given. Such modified images are typically used to clear a supervisor or BIOS password by reprogramming the SPI chip. Without identifying details it should only be written to the board it was taken from or a confirmed identical one. Unpack and check the image size against the flash capacity, and keep a backup of the original contents before flashing.
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 @vinafix_bios. Enginerys does not host this file.
