0 When you upgrade an SX-based processor to a DX- or
Pentium-based processor, you need to change the jumper
setting of Jl to position A.
0 You may need to change DIP switch settings to match the
speed of your new processor. See page 4-7 for more
information.
0 For SX2, DX, DX2, DX4, or Pentium OverDrive processors,
you need to install a heat sink on the chip.
0 After you install the processor and replace the computer’s
cover, run the SETUP program so your computer can
update its configuration. See Chapter 2 for instructions.
(You need only run the program and save the
configuration; you do not need to change any settings.)
Replacing the Microprocessor
Follow these steps to replace the microprocessor chip in your
computer:
1. Remove any video card or other option cards that may be
blocking your access to the microprocessor socket. See
page 4-16.
2. Use the illustration on page 4-3 to locate the microprocessor
on the system board. The microprocessor chip is inserted in
a ZIF (Zero Insertion Force) socket.
Caution
Make sure you ground yourself by touching the metal
surface on the inside of the computer’s back panel before
you touch the processor chip. Then rem ain as stationary
as possible while you install it. Do not touch the pins on
the processor chip. Handle the microprocessor only by
the edges of its case.
