BIOS image for MSI board MS-15811, version 1.1, with the model written as MS-MS-15811 in the name. A 32MB size is listed, suiting a 256Mbit SPI flash, and the RAR is 7.48 MB. It is meant for restoring a corrupted BIOS chip with a hardware programmer such as a CH341A. MSI boards carry their MS- number and revision on the PCB, so confirm both before flashing. Read and keep the original chip contents, and check that the image size matches the chip on your board.
