Working BIOS dump for the MSI B150M Gaming AIO motherboard, MSI number MS-7A77 revision 1.0, an Intel B150 board, packed in an 8.76 MB rar. MS-xxxx is MSI's own board code, printed on the PCB. The image is used to restore a board that fails to POST because of corrupted firmware, by writing it to the SPI flash with an external programmer. Read and save the original chip content first, since it can hold the MAC address and serial, and check the file size matches the chip.
