BIOS archive for the MSI EX623 laptop, board MS-1674 with sub-number MS-16741, version 0C. MSI numbers its notebook boards with the MS- prefix and a four digit code, with a five digit form marking a variant. The RAR is about 1.3 MB and should hold the firmware for SPI reprogramming. Read and keep the existing chip contents before writing, confirm the board number printed on the PCB, and make sure the image size matches the installed flash chip capacity.
