BIOS dump for MSI motherboard MS-15811, which belongs to the MS-1581 series; the extra .306 in the name appears to be a firmware version code. The image is stated as 32MB, matching a 256Mbit SPI flash chip, packed in a 7.04 MB RAR. Technicians reprogram it with an external programmer when the board shows no display or is stuck after a failed update. MSI uses its own MS- numbering, so match the number and revision printed on the PCB, and save the original chip contents first.
