2.6 CPU installation and upgrading
You can upgrade to a higher power Pentium
®
processor at any
time. Simply remove the old CPU, install the new one, and set the
jumpers for the new CPU type and 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 damaged by the
sudden rush of power. Only experienced
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.
2.6.1 Installing a CPU in the PGA type socket
1. If you are upgrading the CPU, remove the old CPU from the
socket. If it is difficult to remove, you may find chip lubricant
(designed for pin-grid-array devices, PGAs) and a chip puller
helpful. Both are available at electronics hobby supply stores.
2. Plug the new CPU into the empty socket. Follow the
instructions that came with the CPU or math coprocessor. If
you have no instructions, do the following: Lubricate the CPU
pins with lubricant made for PGA devices. This will make the
new CPU slide in much more easily, and reduce the chance of
damaging it. Next, carefully align the CPU so that it is parallel
to the socket and the notch on the corner of the CPU
corresponds with the notch on the inside of the socket. Gently
slide the CPU in. There will probably be a gap between the
CPU and the connector when it is fully seated - do not push too
hard!
