Their non-volatile characteristic makes several processes in existing boot mechanism unnecessary. If these processes are eliminated, the system users can spend shorter time to control the system. ...
In this paper, we propose a technique which uses only one kernel image for every booting by using nonvolatile memories. ...
Boot process of Linux Booting is a process that makes CPUs, memories and other devices to initialize and operating system to run, so that the user can use the stabilized system. ...
