Description
This bit is set by the SSUA to force the Boot Monitor to use the second copy of
the configuration script in safe mode.
If bit is set to 1, the Boot Monitor clears this bit and loads the alternative
configuration record to the one specified by the “Image selector”.
This bit indicates that the current Boot Monitor Config (which specifies the kernel
and/or root filesystem) is started in safe mode; used only as an indication of boot
status and set by the Boot Monitor immediately after clearing bit 7.
This bit selects the active configuration record to be loaded (either the first or
second copy). This bit may be modified only by the SSUA on a control plane
validation request.
