2.36 CPU installation and upgrading
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!
