Restarting the Computer
You occasionally may want to return the system to its startup state without turning off the
power. This is called restarting or rebooting the system (sometimes called a warm boot,
as opposed to a cold boot, which involves turning the power off and on again).
Caution: Any data In main memory (RAM) will be erased when you restart
the computer. Be sure to save the file you are working on before you restart the
computer.
To restart the computer, press and hold the Ctrl and Alt keys, then press the Del key and
release all three keys. The computer responds as if power was just turned on-it performs
an internal check, then loads MS-DOS from the hard disk. When restarting, the computer
bypasses the initial memory check it performs during a cold start.
