5.4.1 Pre-installed on Flash
When an 8585 with a pre-installed operating system is started, the operating system is loaded following the
BIOS boot messages.
System-specific device drivers—such as those for graphic, sound, network and touchscreens—are also pre-
installed.
In 8585 units with a pre-installed operating system, the system is located on the C partition.
