BIOS and keyboard EC firmware for MSI board MS-16R51 revision 1.2, supplied together in a 6.21 MB RAR. MSI numbers its own laptop boards in the MS-xxxxx format, with the last digit marking the board variant. The EC part controls power-on, charging and keyboard, so both chips usually need correct images for a stable machine. Verify the board number and revision on the PCB, dump the original chips with a programmer, and check each image size against its flash chip.
