BIOSTAR B45M2 Ver. V6.x BIOS

BIOS .rar 18.5 MB Shared

BIOS image for the Biostar B45M2 motherboard at hardware version 6.x, listed under ECS, in an 18.5 MB RAR archive. The version refers to the PCB revision, so check the Ver. marking on the board before flashing. Write the image to the SPI flash with a programmer to recover a board stuck on a black screen or showing a corrupted BIOS. Read and save the original chip contents beforehand, and confirm that the file size matches the capacity of the flash chip fitted to your board.
