BIOS package for the Gigabyte GA-B250M-HD3 motherboard, revision 1.0, compressed as a 5.39 MB ZIP. The name does not say whether it is a factory update file or a full chip dump, so check the contents and the image size against the SPI flash on the board before programming. Confirm the PCB revision reads 1.0. When writing with a CH341A or similar programmer, read and save the original chip first so the board's own data and settings 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.
