BIOS dump for a board labelled C.B150M-K V20A, described as working in the name, delivered as a 9.69 MB RAR. B150 points to the Intel B150 chipset and V20A is likely the board revision, while the C. prefix appears on some Colorful boards, although no brand is given here. Technicians flash such an image to the SPI chip with a programmer to recover a board stuck without POST. Check the model and version printed on the PCB, back up the existing chip, and confirm the image size matches its capacity.
