Most users perform a hard disk boot when starting the system for general operations.
The system finds all information necessary to the boot process on its disk drive. The ROS Kernel Init Phase diagram illustrates the kernel initialization that takes place before the system boot process is started. This boot list can be altered to suit your requirements using the bootlist command. In either case, the first valid boot device found in the boot list is used for system startup. If no user boot list exists, all adapters and devices on the bus are checked.
