ASUS P8H61-M LE/CSM motherboard BIOS, version 4501, 4 MB ROM. The CSM suffix identifies the Corporate Stable Model variant of the P8H61-M LE, which has its own BIOS line separate from the retail board. A 4 MB image corresponds to a 32 Mbit SPI chip and includes the Intel ME region typical of H61 platforms. Use it to update the firmware or to reprogram a chip on a board that will not start. Save the original contents first and confirm the variant printed on the board.
