Archive of 1.05 MB in RAR format labelled FA808UH with an RTX 5050 GPU variant. Only the model code and graphics chip are given, so the precise contents are unknown until extracted; it is most likely firmware tied to that GPU configuration. Before writing any image, read and store the original chip with a programmer, compare the board identification on the PCB, and confirm the file size matches the flash device so the image will fit and boot correctly.
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.
