Displaying and Setting the Secure Boot Mode
This section provides instructions for displaying and setting the secure boot
mode for your Model 743.
There may be circumstances in which you would not wish to allow anyone
to attempt to boot your system from a device other than the device you have
specified, or to control the system from any console other than the one you
have designated. This can be an important consideration in secure installa-
tions.
If you set up your system in such a way that it is physically impossible for
unauthorized persons to disconnect it from its designated boot device, you
can guarantee that the boot console handler cannot be used to boot the sys-
tem from an unauthorized device or to change the console path.
With Secure Mode turned on (set to YES), the boot console handler cannot
be activated. Thus, you are assured that your system’s security cannot be
compromised through interaction with that interface.
CAUTION: Once the secure boot mode is activated, the only way to turn it off is to
disconnect the boot device. When you turn on your system after isolating it from
its boot device, the boot console handler interface reappears. You can then turn
the secure boot mode off, turn off your system, reconnect the boot device, and
turn the system back on.
Follow these steps to display your current secure mode and to set your
Model 743 to secure boot mode.
