Installing a New Processor Chip
If you have the 486SX/33 system, you can enhance your
system’s performance by installing an Intel OverDrive
processor (ODP486DX-33) or a 487SX/33 microprocessor with
built-in math coprocessor.
Complete instructions for installing the processor are provided
in the manual that comes with it. Please follow those
instructions carefully, along with the following guidelines:
Although the OverDrive processor User’s Guide instructs
you to remove the main system board from the computer,
this is not necessary. You can install the OverDrive
processor while the board remains inside the computer
case; just remove the computer’s cover.
Refer to the illustration on page 2-3 to locate the
microprocessor socket on the main system board. If this
socket is empty, you can install the new processor directly
in the socket. If this socket contains the CPU chip, however,
you need to remove it before you install the new processor.
If you need to remove the existing microprocessor, lift the
lever at the base of the socket to release the chip and then
remove it. (This eliminates the need to use the chip puller
tool to remove the chip.) When you install the new
processor, push the lever down to secure the new chip in
the socket.
If you remove the CPU chip to install an OverDrive
processor or 487SX/33 chip, you need to change the
settings of jumpers J5 through J8. See page 2-6.
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 of the Setup Guide
for instructions. (You need only run the program and save
the configuration; you do not need to change any settings.)
