BIOS dump for the MSI MS-1781 laptop main board, with the PCB identifier MS-17811 also given in the name, and marked as tested OK by the person who saved it. The RAR archive, 3.00 MB, should hold the SPI flash image plus perhaps notes. MSI numbers its own notebook boards in the MS-xxxx style, with the extra digit usually marking the PCB version. Read and back up the original chip with a programmer such as a CH341A before writing, and confirm the board marking and the flash chip capacity match the image size.

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 →
