Problem Solving
Resetting the System
There are two ways to reset the system:
Reset button
Pushing the reset button clears the system memory,
restarts the POST, and reloads the operating
system.
Power off/on
Turning the power off and then on with the push-
button switch on the front panel has the same effect
as pushing the reset button, except that power is
halted to all peripherals.
