BIOS firmware package for the Biostar B250GT5 desktop motherboard, version 5.x hardware revision, in a 13.9 MB RAR archive. The B250 designation points to the Intel B250 chipset platform named in the model. Such an image is used to recover a board that fails to POST after a corrupt update by writing the SPI flash with an external programmer. Read and save the original chip contents first, and check that the image size matches the flash chip capacity, because a mismatched file will not fit or boot.
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.
