BIOS image for the TB360-BTC PRO 2.0, a mining-oriented motherboard, version 6.x, sized for 16 MB flash according to the name. The archive is a RAR of about 11.2 MB; the board maker is not given. B360 in the model name suggests an Intel B360 chipset. Write the extracted file to a 128 Mbit SPI chip with a programmer when the board fails to boot after a bad update or corruption. Back up the existing contents before writing, and confirm the extracted image is exactly 16 MB so it fits the chip.
