Firmware for a Grundig notebook on a board labelled A15YA revision 2.1 in UMA configuration, meaning integrated graphics only. The name gives no full model, and the board maker is not stated. The 2.79 MB 7z archive holds a BIOS image for reflashing the SPI chip with a programmer. Check that the A15YA marking and revision on the PCB match and that the board has no discrete GPU. Read and back up the existing chip first and confirm the image size fits its capacity.
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.
