Firmware archive for an HCL device labelled only 12.1, which likely refers to a 12.1-inch screen model, though no model, board number or version is given. The RAR is 438 KB. Because the name is so vague, open it and look for readme files, BIOS strings or a model ID inside the image before relying on it. Dumps of this kind are written with an SPI programmer to recover a corrupted BIOS. Always save the original chip contents first and confirm the size matches.
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.
