Booting the CMA24BT cpuModule for the First Time
You can now apply power to the cpuModule.If you press ESC on a keyboard while booting, the cpuModule
will enter Setup. Once you have configured the cpuModule using Setup, save your changes and reboot. If
you don’t presse ESC , the cpuModule will boot using the current settings.
Note You may miss the initial sign-on messages if your monitor takes a while to power on.
Note By default, cpuModules are shipped with a UEFI (Unified Extensible Firmware
Interface) shell. When no other bootable device is installed in the system, the system will boot
to it exclusively. This internal bootable shell may be disabled in the BIOS screen’s boot menu.
WARNING Incorrect modifications to the BIOS can cause your system to break. If you are
unsure of any changes made to the BIOS there is a Load RTD Defaults option under the Exit
tab in the SCU . This option restores the BIOS to the default factory settings.
