BIOS image for the Biostar TB250-BTC PRO mining motherboard, built on the Intel B250 chipset with twelve PCIe slots per the BTC-12P tag, sized for an 8 MB flash chip. Use it to recover a board that hangs or will not post after a bad update, by writing the SPI chip with a programmer such as a CH341A. Read and save the existing chip contents first, since they may hold the board's MAC address. Also confirm the chip is 8 MB, because an image of the wrong size will not fit.
