BIOS package for MSI notebook board MS-16K21, revision 2.1, marked working and containing both an 8 MB and a 1 MB image in a 4.36 MB RAR. MSI numbers its laptop boards with the MS-16xx pattern, and the two files likely correspond to separate flash chips, such as a main BIOS chip and a smaller EC or secondary chip. Identify each chip's capacity before writing, read and save the existing contents with a programmer, and confirm the board code and revision printed on the PCB.
