RAR archive holding a BIOS dump for an LC55-15C board with number 19792-3, marked as a fully working image, and tagged with the part reference 448.OK106.0031. The 19792 style number follows the Wistron board numbering pattern, so the board maker is Wistron. Extract the archive and write the image with an SPI programmer such as a CH341A, but read and save the original chip contents first, and confirm the chip capacity matches the image size and that the board number and revision on the PCB agree.
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 @pkbiosbdv. Enginerys does not host this file.
