5)Select <8> to have the system ignore the software version of the Boot ROM program, its extended segment, and application program for backward compatibility. If you fails to upgrade the software because the system considers that you are using an “invalid version” even when the correct version is used, you can use option 8 to ignore the version check during software upgrading. Note that this option works only once after you select it. Then, the system resumes version check at reboot.
