BIOS image for an MSI mini notebook marked MS-N082, with U180 and 418UK in the name, probably the model variant and a regional or SKU code. It comes as a 951 KB RAR, a size typical of older netbook-era flash chips. Such a dump is used to restore a netbook with a corrupted BIOS by writing the chip with an external programmer. Confirm the board identifier on the PCB matches MS-N082, save a backup of the current chip, and check the file size matches the flash before writing.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
