updatekernelflag
This command allows you to update the configuration of the Linux bootloader after a new kernel
image has been written to the UPGRADE kernel partition of Meridian II FLASH disk. You may also
use it to reset the default back to the FACTORY kernel partition. Refer to

for detailed instructions for performing the
upgrade procedure. One argument is accepted, whose value is either 0 or 1, which causes a flag to be
set that indicates to the bootloader which kernel image should be loaded by default. If an argument
value of 2 is given, then the currently configured default kernel is shown.
