BIOS package for the Biostar TB250-BTC PRO motherboard, hardware version 6.1, supplied as a 4.39 MB ZIP archive. This mining-oriented B250 board needs firmware matching its PCB revision, so check the version silkscreened on the board before flashing. The image can be written through the vendor update tool when the board still boots, or with an SPI programmer clipped onto the BIOS chip when it is dead. Save the existing chip contents before writing anything so the original state can be restored.
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.
