BIOS and KBC firmware for a Casper all-in-one PC, model TSH231H NPB, revision A, in a 3.2 MB ZIP. The KBC image is the keyboard or embedded controller firmware, which handles power-on logic, so both files may be needed for no-power or no-boot faults. Write each image to its own chip with a programmer after reading and saving the originals. Check the board marking and revision letter on the PCB before flashing, and confirm each image size matches its chip.
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.
