Installing the CPU

The SBC-556/L CPU card supports most Pentiums and their
compatible CPUs. The system's performance depends on the CPU
you choose. You can install or upgrade the CPU in the board's PGA
socket by following the procedures outlined below. If your system
has an existing CPU, you need to remove it before installing the
new CPU.
Removing a CPU
1. Disconnect power from the chassis, and unplug all connections
to the CPU card. Then, remove the CPU card from the chassis
by following the instructions in the user's manual for your
chassis.
2. Lift the CPU out of the PGA socket. The old chip may be
difficult to remove. You may find spray chip lubricant, designed
for pin-grid-array (PGA) devices, and a chip puller helpful.
These are available at electronics hobbyists' supply stores.

your chassis whenever you are working on it. Do
not make connections while the power is on
because sensitive electronic components can be
damaged by the sudden rush of power. Only
experienced electronics personnel should open
the PC chassis.
Always ground yourself to remove any static
charge before touching the CPU card. 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.
