2. If you are upgrading the CPU, remove any existing CPU from
the socket. (See Chapter 1 for help locating the socket.) The
old chip may be difficult to remove. You may find spray chip
lubricant (designed for pin-grid-array devices, PGAs) and a
chip puller helpful (available at electronics hobbyist's supply
stores).
3. Plug in 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 pins
of the CPU. Use lubricant designed for use with PGA devices.
This will make the new CPU slide in MUCH easier and reduce
the chance of bending pins or other damage. Next, carefully
align the CPU so it is parallel to the socket and the notch on the
corner of the CPU matches with the notch on the inside of the
socket. Carefully slide in the CPU. There will probably be a
gap between the CPU and the connector when it is fully seated
– do not push too hard!
4. Switch jumpers JP2, JP3 and JP31 to match the new CPU
according to the following table:
SX-25
SX-33
DX-25
DX-33
DX2-50
DX2-66
DX4-100 (3.45 V)
5. Reinstall the CPU card according to the instructions in
Chapter 2.
