Firmware archive for a Casper Nirvana laptop with an Intel Core i7, labelled 940M, which most likely refers to the GeForce 940M graphics option, built on board C15B revision 2.0. The 7z archive presumably holds a BIOS dump for reprogramming the SPI flash after corruption or a failed update. Open it with 7-Zip and compare the image size with the flash chip before writing. Confirm the board marking and revision printed on the PCB, and keep a backup of the original chip contents in case the dump does not suit your unit.
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 @biosfiles. Enginerys does not host this file.
