MSI board MS-14321, revision 0C, with both the system BIOS and the embedded controller (EC) firmware packed into a 495 KB RAR archive. The MS-xxxxx code is MSI's own mainboard numbering, and the revision printed on the PCB should read 0C before flashing. EC firmware governs power sequencing, charging, keyboard and fans, so a corrupt EC chip often gives a dead or no-power board. Read and save the original chips with an SPI programmer first, and check that each image size equals the capacity of the chip it goes onto.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
