We wish to thank you for purchasing the PowerForce G4 upgrade card for your PowerMac G4 computer. The
PowerLogix PowerForce G4 is a PowerPCTM processor card that will enable your Power Mac G4 to run at
maximum speed with no compromises or permanent modifications.
This manual provides all the information you need to install the card. Please read the manual completely
before installation. It will speed up the installation process and prevent downtime later.

Warning! As with any hardware upgrade, back up your hard drive prior to installation.
The PowerForce G4 is a static-sensitive device. It is susceptible to invisible damage if not protected during
installation. Do not remove the product from the anti-static bag until you are ready to install it.
We recommend proper grounding by using a grounding strap. Alternatively, touch the power supply of the
computer to release any static build-up prior to installation. The computer must remain plugged into an AC
outlet for this to work properly. Make sure to work in a clean and static-free area, and avoid wearing clothing
that retains static charges.
Although these instructions should provide enough detail for almost anyone to install the PowerForce G4, if
you are not comfortable opening your Mac, you can always have an authorized service provider install it for
you.

Pre-Installation Instructions
Before proceeding, refer to the illustrations in this manual to familiarize yourself with the PowerForce G4
processor card. The PowerForce card plugs into a socket on the motherboard of the Mac. Your Mac may vary
slightly from the illustrations; don’t panic! It is not difficult.
Before installing your card, if you plan to use OS9 (actually boot from OS 9, as opposed to running Classic in
OS X) you must remove the CPU Plugins file from the “/System Folder/Extensions/Multiprocessing/” folder
after booting using the original CPU.
Firmware
IMPORTANT: This upgrade REQUIRES the PowerLogix 7447/7457
Firmware Update provided on CD or it WILL NOT WORK.
1) Your computer must have the latest Apple Boot ROM version for your particular model of G4.
2) To determine what version Apple Boot ROM your computer has, run Apple System Profiler (System
Profiler in OS X) and look under Hardware Overview.
3) If your computer has an earlier version than what is listed below, download the latest version and
follow the instructions.
AGP, Gigabit Ethernet: Apple Boot ROM version 4.2.8
If you need to update, version 4.2.8 firmware is available here:
http://docs.info.apple.com/article.html?artnum=120068
Page #5PowerLogix PowerForce 7447/7457 Installation Manual
4) Insert the Powerlogix Firmware Update CD into the CD-Rom drive. AGP and Gigabit Ethernet
PowerMacs: use 7457 Firmware Update 1.2f3 or higher. Digital Audio and QuickSilver PowerMacs: use 1.2f6
or higher.
5) Shut down your Mac.
6) While you press the programmer’s button, press the Power button to start up your Mac. You will hear
a long tone. At the same time (if you have enough hands) press and hold the ‘C’ key. This will tell the Mac to
boot from the Powerlogix Firmware Update CD.
7) The Firmware Enabler CD boot screen will appear and you will see the following:

Please Select one of the following options:
1. Install 7447/7457 enabler patch
2. Install 7447/7457 PLL patch
3. Install L3CR extended ratios
4. Install all 7447/7457 patches
5. Set up NVRAM for booting into Mac OS 9
6. Shut down
7. Exit to Open Firmware
Page #6PowerLogix PowerForce 7447/7457 Installation Manual
Select option 4 from the above choices. You will see a notice that verifies the flash has burned successfully
and your computer will shut down in 30 seconds.
Note: if your computer was previously patched for 7457 compatibility, you will simply be prompted to add
7447 compatibility and the menu above won’t appear.
Mac OS 9.2.2 Compatibility
If you intend to boot using Mac OS 9.2.2, start up the computer again while holding down the “C” key. You
do not need to hold down the programmer’s switch during this step.
Press “5” to enable Mac OS 9.2.2 compatibility.
Note: This step is not required to operate Classic under OS X; it is only required if you intend to actually boot
directly into Mac OS 9.2.2.
After a few second, the NVRAM will be updated, and your Mac will shut down in 30 seconds.
Note: If you reset the PRAM, the NVRAM code for OS9 compatibility is cleared, and you will have to boot
from the Firmware Update CD and perform this process again in order to boot into OS9.
Note: Make sure any OS 9 boot volumes have the CPU Plugins file removed from the System Folder/
Extensions/Multiprocessing folder, or your machine will not boot.
Note: Any boot CDs must also have CPU Plugins removed. This includes any emergency disks from Norton,
Disk Warrior, etc. You will need to make backup copies of these boot CDs with the CPU Plugins file removed
from the System Folder/Extensions/Multiprocessing folder. If CPU Plugins is present in that location on the
CD, it will prevent the machine from booting, as CPU Plugins is not 7457-aware.
Your Mac is now compatible with the Powerlogix processor
upgrade. Please proceed to the installation instructions.

Mac OS Installations
Before proceeding to hardware installation, make sure your G4 has the proper version of the OS
installed. (Refer to page 4.)
Installing the CPU Card
Power down the computer. Review the static-safe procedures from Page 4 before proceeding.
Unhook the latch on the side of the case and pull down the cover.
Locate the original processor card in your computer. Pictured above with #1 is the location in an AGP
“Sawtooth” or “Gigabit Ethernet” system. If you have a Power Mac G4 “Digital Audio” or QuickSilver system
your processor card will be located where the #2 is.
Page #8PowerLogix PowerForce 7447/7457 Installation Manual
Remove the heat sink retainer clips. The retainer clips are fairly strong springs. Press down firmly but carefully
with your finger on the center of the clip until the leg of the clip frees from the bottom of the processor card.
Pull the leg out until it slips over the edge of the processor card. This may require an additional tool, such as
a screwdriver to pry, or a pair of needlenose pliers. Remove both clips and remove the heat sink.
Note: If you have certain Digital Audio or Quicksilver systems, you will have to remove a plastic fan shroud
and fan to expose the heatsink. Unplug the fan and remove the shroud, and set it aside.
Remove the screws that hold the Apple CPU card in place. Be careful not to lose the screws as you will
be reusing them to install the new PowerLogix processor upgrade card. If you have a Digital Audio or
Quicksilver system, you will have 4 screws to remove. You will only reuse 3.
Page #9PowerLogix PowerForce 7447/7457 Installation Manual
Carefully pull the original processor card straight up and out of the motherboard socket. Remove the
protective cap from the socket on the PowerForce G4. (See figure below.) Place the cap on your original
Apple CPU card.
Page #10PowerLogix PowerForce 7447/7457 Installation Manual
Align the CPU card with the motherboard by looking through the screw holes in the PowerForce card. Once
the card is aligned, snap the PowerForce card into the motherboard socket. It will only install one way. There
may be a positive ‘click’ when it is plugged in completely, however this is not always the case; sometimes
there is no positive detent even though the connector is installed properly. DO NOT EXERT EXCESSIVE
FORCE!
Using the original screws, secure the PowerForce card into place on the motherboard. This is a little tricky as
the screws have to be placed through the heatsink; a magnetized screwdriver may help. To install the screw
underneath the fan, you may want to remove the fan (if already attached) to aid installation of the screw. If
removed, be sure to follow the instructions below to reattach the fan correctly.
CPUs with included Fans:
Connect the 4 pin wiring harness for the fan to one of the disk drive power connectors. A pass thru
connector is provided.
Attach the fan guard to the top of the fan. Mount the fan on the heat sink as shown in the photo, and secure
with the two screws.
Make sure the airfl ow indicator on the fan is in the proper direction. Air should be blowing down onto the
card. Refer to the arrows in the photo below.
The label on the center of the fan should face towards the heatsink, and will not be visible.
Close the case cover. Do not operate the Mac with the cover open as the case needs to be closed for
proper cooling. Some Mac models may have fans, but the cover still should be closed when operating the
PowerMac.
