MSI firmware archive covering the MS-17L3 laptop and the MS-15831 board, containing a VBIOS for an RTX 3060 GPU, coded GN20-E3-A1, along with a system BIOS. MS-prefixed numbers are MSI's own model and mainboard designations. Technicians use such a pack to restore a corrupted BIOS SPI chip or a damaged graphics VBIOS with a programmer like the CH341A. Read and save the original chip contents before writing anything. Confirm that the image size matches the flash chip capacity and that the GPU variant on the board is the RTX 3060 named here.
