SPEED Utilit y

The

SPEED

utility enables you to set the current

CPU

operating speed to low, medium, or high. However, because
the faster speeds consume more power, you may want to
select the low or medium speed to conserve power when
you are operating the computer on its internal battery.

You can change

CPU

speed in Setup (as described elsewhere

in this manual) or by pressing CTRL-ALT-

or CTRL-ALT-

(except on

DX4

models).

Note: For this utility to work correctly on a DX4 model,
EMM386 or other memory managers must not be loaded.
