Manually upgrade the boot loader
You must first boot to the old helper file where there is an option to update the boot loader in the
helper menu. Then you reboot and reimage the hard-disk drive. Refer to in the 4.x documentation.
You no longer need to boot to the helper to load the 5.0 system image. The 5.0 system image contains
everything needed to reimage the NM-CIDS.
The new bootloader works with the 4.x system image; however, you must boot to the helper to load
it.
