BIOS archive for a board identified as WCBT112X version 1.0, packed as a 4.76 MB RAR. The name gives no brand or device model, so confirm the board marking carefully before using any image inside. Extract the archive, check the file sizes against the capacity of the SPI flash on the board, and program it with an external programmer such as CH341A or RT809. Always read and save the original chip contents first so the board can be returned to its previous state if the image does not fit.
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 @biosarchive. Enginerys does not host this file.
