BIOS dump for an MSI board MS-1783 with PCB number MS-17831, version 1.0, packed in a 4.08 MB RAR archive. MSI uses the MS-xxxx code for the model and adds a digit for the specific PCB, so the printed MS-17831 marking is what to compare on the board. The image is used to reprogram the SPI flash with a hardware programmer when the machine does not post. Read the original chip before writing, and make sure the image size matches the flash capacity so it fits correctly.
