BIOS archive for the ASUS X200CA, labelled with the configuration code CT156H. No board revision appears in the name, so check the revision printed on the PCB before use. The 3.39 MB RAR holds an image for the SPI flash, which technicians program with a CH341A or similar device when a small notebook will not boot or has corrupted firmware. Extract the file, compare its size with the chip capacity, and read out and keep the original contents before writing anything to the board.
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.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
