MSI notebook BIOS package for the MS-1782 mainboard, version 2.0, with the name also listing the sub-variants MS-17821 and MS-17822. MSI numbers its own laptop boards in the MS-xxxx format, and the extra digit marks model-specific builds of the same PCB. The 4.12 MB RAR likely holds an SPI flash image. Confirm which variant and revision is printed on your board, back up the existing chip with a CH341A or similar programmer, and verify the extracted image size fits the flash chip before writing.
