Firmware image for a Casper CGU series laptop on the C15MG board, provided as a 2.83 MB 7z archive. No revision, GPU or flash chip information is included in the name. Dumps like this are used to recover corrupted BIOS by programming the SPI chip with an external tool such as a CH341A. Before writing, read and keep the original contents, verify the board marking on the PCB reads C15MG, and confirm the image size matches the installed chip.
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.
