Restarting the computer
You may sometime 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 the Del key while holding down the Ctrl and Alt 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.
