Installing An Upgrade Processor - HP Vectra XU 5/XX Introduction Manual

Installing an Upgrade Processor

There are two ZIF (Zero Insertion Force) sockets on the PC's system board. These sockets
allow upgrade processors to be installed easily. The PC is shipped with one Pentium
processor installed, which can be upgraded as follows:
A second (dual) Pentium processor can be installed in the empty ZIF socket. This
installation will require jumper J24 to be changed.
An OverDrive for Pentium processor can be installed in the empty ZIF socket. This
installation will require the system board switches to be changed.
Check with your dealer for supported upgrade processors, and information about operating
systems which support dual processing.
CAUTION Static electricity can damage electronic components. Turn all equipment OFF.
Avoid wearing wool or polyester and don't let your clothes touch the accessory.
To equalize the static electricity, rest the accessory bag on top of the power
supply while you are removing the accessory from the bag. Handle the
accessory as little as possible and with care.
To install a dual Pentium processor:
A second Pentium is supported only by certain advanced operating systems (Windows NT,
Unix, OS/2). Drivers are also required to use a second processor. These drivers are supplied
by HP or by the operating system vendor.
1. Remove the PC's cover and power supply, as described earlier in this chapter.
2. Unlock the empty ZIF socket by raising the locking lever.
3. Position the second processor over the empty ZIF socket, aligning the processor and
socket corner markers correctly.
4. Place the processor into the socket. If the processor is not seated correctly, do NOT
press it into the socket. Lift it out and try again.
5. Lower the ZIF socket lever to lock the processor into place.
