Firmware for the Lenovo 330-15IGM laptop, labelled Main, which most likely means the mainboard BIOS image. No board number or chip type is given, so the 3.70 MB RAR has to be opened to check its contents. Such a dump is used to restore a board with no image, a boot loop or a locked or corrupted BIOS by writing it to the SPI chip with a programmer. Compare the board number printed on the PCB with the source of the file, keep a backup of the original chip, and confirm the size fits the flash.
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.

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 →
