BIOS and EC firmware for the 22V240 all-in-one computer, board code EAX65399816, in a 3.08 MB RAR archive. Having both images lets a technician restore the system flash and the embedded controller code, which handles power-on, keyboard and fan behaviour. This helps with no-power, no-display or boot-loop faults. Write the files with an SPI programmer after reading and saving the current contents. Make sure the EAX number printed on the PCB matches, and that each image fits the capacity of its chip.
