Resetting the Computer
You can reset the computer to load a different operating system or to
reload the current operating system. For example, if an error occurs and the
computer does not respond to your keyboard commands, you can reset the
computer and try the same operation again. However, resetting erases all
data in the computer’s temporary memory (RAM), so reset your computer
only as a last resort.
In MS-DOS,
you can hold down
Ctrl
and press
C
to stop a program’s
operation and return to the MS-DOS command prompt. If an error occurs,
try this method before you reset the computer.
WARNING: Do not reset the computer to exit a program unless
you have to. Some application programs classify and
store new data whenever you exit the program prop-
erly. If you reset the computer while such a program
is running, you may lose data.
