Upgrading the

Pentium Processor The 166 MHz Pentium processor can be upgraded to a 200

MHz or 233 MHz processor. The 200 MHz processor can be

upgraded to a 233 MHz processor.

CAUTION: Installing the processor upgrade incorrectly may cause

damage to the processor board. Compaq recommends that you

have a Compaq authorized dealer, reseller, or service provider

install the processor upgrade. If you plan to install it yourself, read

all the instructions carefully before you begin.

To replace the installed processor with a processor upgrade,

complete the following steps:

!WARNING: To reduce the risk of personal injury from hot

surfaces, allow the internal system components to cool before

touching.

1. Remove the front bezel and any expansion boards that

block access to the processor.

2. Remove the drive cage.

CAUTION: When replacing the processor, you must release the

heatsink retaining clip prior to pulling the ZIF socket handle. This

clip engages the processor socket to hold the heatsink in place

.

3. Remove the heatsink retaining clip 1 by pressing down on

the clip’s extended tab until it releases from the safety catch.

4. Lift the heatsink 2 off the processor.

5. Release the original processor from the socket by pulling

the handle on the ZIF socket out and upward 4.

6. Lift the processor 5 out of the socket.
