System Setup and Boot
Basic system information regarding system information, setup, power management, hardware,
and passwords is maintained in the Setup Utility held in the system ROM. The Setup Utility is
accessed by pressing the F10 key when prompted (on screen) to do so during the boot sequence.
If the screen prompt opportunity is missed, a restart will be necessary. For more information
about Setup Utilities refer to the Service Reference Guide.
