Firmware archive labelled only as Dell Inspiron 7380, with no board number, revision or chip details in the name. At 7.22 MB packed it most likely contains a full SPI flash image, but open it and check what is inside before use. Compare the image size with the capacity of the flash chip on the board, since a mismatched file will not fit. Back up the existing chip contents with your programmer, and confirm the model sticker matches before writing to a Dell 7380 board.
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.
