Device Software Overview
Device software comprises the Boot ROM program and the system boot file. After powered on, the
device runs the Boot ROM program, initializes the hardware, and displays the hardware information.
Then the device runs the boot file. The boot file provides drivers and adaption for hardware, and
implements service features. The Boot ROM program and system boot file are required for the startup
and running of a device. Figure 10-1 illustrates their relationship.
