CPU installing and upgrading
You can upgrade to a more powerful Pentium II/III CPU at any time.
Simply remove the old CPU, install the new one, and set the
jumpers for the new CPU speed.
Warning! Always disconnect the power cord from your
chassis when you are working on it. Do not
make connections while the power is on as
sensitive electronic components can be dam-
aged by the sudden rush of power. Only experi-
enced electronics personnel should open the PC
chassis.
Caution! Always ground yourself to remove any static
charge before touching the PC board. Modern
electronic devices are very sensitive to static
electric charges. Use a grounding wrist strap at
all times. Place all electronic components on a
static-dissipative surface or in a static-shielded
bag when they are not in the chassis.
