RAR archive of 174 KB labelled GL703GM with a GTX 1070 GPU tag. The name gives only the model code and graphics variant, so the exact contents are not stated; the small size suggests a firmware image such as a VBIOS rather than documentation. Extract it and check what is inside before use. When writing any ROM, dump the original chip with a programmer first, verify the GPU and board variant match your unit, and ensure the image size fits the target flash 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 @boardsscanrepo. Enginerys does not host this file.
