BIOS firmware archive for the MSI Modern 15 A10RAS laptop, model code MS-E1551 as given in the name. The RAR is 5.61 MB compressed and likely holds an SPI flash image for reprogramming the BIOS chip, though contents are not itemised. Technicians use such a dump to recover a board that will not post after a failed update or corrupted firmware, writing it with a programmer such as a CH341A. Read and save the original chip contents first, and confirm the image size matches the flash capacity before writing.
