Preparing the
MACh Speed ZIF
Card for
Installation
Before installing the MACh Speed ZIF card into your system, it is necessary to prepare the card for
the installation.
Adjusting the Jumpers on the MACh Speed card
Before installing the MACh Speed card, you need to adjust the jumpers in order to set the
speed of your upgrade card.
The jumpers are adjusted on the card itself, you do not need to changer the jumpers on
the motherboard of your PowerMac.
The jumpers are set from the left to the right, when the XLR8 logo is at the top left
corner and the jumper block at the right side of the card.

Installing the
MACh Speed ZIF
Upgrade Card
This chapter provides information for installing the MACh Speed ZIF card into individual systems.
General Installation Instructions
Before installing your MACh Speed ZIF upgrade card, you should review this short section.
1. Attach the anti-static wrist strap to the end of a plugged-in power cable, such as the one used for
your computer. The wrist strap will ensure that you are well grounded and avoid any unexpected
static discharges.
2. Prepare the system and work area.
• Prepare your work area by ensuring that you have a well-lighted space, preferably not on
carpet (static), and away from all magnetic devices.
• Turn off the computer and disconnect all cables.
Installing the CPU card is technically challenging. If you prefer, you can ask an Apple-authorized
dealer or service provider to install it for a fee.
If you attempt to install the card yourself but experience difficulties, it is recommended that you
have an Apple-authorized service provider complete the process. Apple does not warranty damage
caused by improper removal or installation of CPU cards.

The default settings are the following:
Applying the thermal grease
The MACh Speed ZIF upgrade card ships with a box containing thermal grease. The thermal grease
needs to be applied onto the processor in order to improve the heat transfer to the heatsink.
1. Attach the anti-static wrist strap to the end of a plugged-in power cable, such as the one used for
your computer. The wrist strap will ensure that you are well grounded and avoid any unexpected
static discharges.
2. Apply a small amount of heatsink thermal grease to the center of the CPU.
3. Your CPU is now ready to be installed.

Installation in a Power Macintosh G3 Blue & White
and PowerMac G4 (PCI Graphics)
IMPORTANT: If you are installing a G4 processor into your PowerMac G3
Blue&White, you will have to update the firmware of your computer first.
Updating/patching the firmware is not necessary on PowerMacs G3 Beige
and G4.
Updating the firmware version 1.0 to version 1.1:
The XLR8 Firmware updater works only with version 1.1 of the original Apple firmware. If
you have not updated your firmware to version 1.1, it will be necessary to update your firmware.
YOU MUST BOOT INTO MAC OS 9!
1. Insert the XLR8 Universal CD into your CD-ROM drive
2. Open the folder “For B&W G3s...”
3. Double-click the file “1-G3 Firwware Update...”if you DO NOT have the latest 1.1f4.
4. This will open a disk image on your desktop.
5. Open thedisk image and double-click on the installer file.
6. Launch the installer
7. Follow the on screen instructions.
8. Click the shutdown button
9. While holding down the Programmer’s button on the front of the computer, power
up your computer (this is the indented button).
10. You will hear a long tone. Once the tone stops, you can release
the programmer’sbutton. The firmware has been updated.
Applying the XLR8 Firmware patch:
The Apple Firmware v.1.1 of the PowerMac G3 B&W has been
designed not to run with G4 processors. Applying the XLR8
firmware patch allows you to install your G4 upgrade.
1. Insert the XLR8 Universal CD into your CD-ROM drive
2. Open the folder “For B&W G3s...”
3. Launch the "2-XLR8 Firmware updater...". You will be prompted to shutdown your
computer
4. Startup the computer while holding down the programmer’s switch depressed until
the long tone stops, then release the switch.
Note: The XLR8 Firmware updater works only with version 1.1 of the original Apple
firmware. If you get an error message while applying the XLR8 Firmware updater, you are
probably running version 1.0 of the firmware. You will have to first update your Apple
firmware to version 1.1.

5. Install the MACh Speed ZIF into your system.
• The MACh Speed ZIF Upgrade will face the same direction as the older card that you
just removed (note the missing pin.)
• Holding the card by the edges (do not depress the center of the card), line up the
pins and insert the card straight down. Insertion should require only minimal force.
• Lower the ZIF Socket release lever to lock the card into the socket.

• Press down on the front end of the clip to snap onto the lock tab on the front of the
processor socket.
6. Raise the computer’s side panel and press it against the case. Squeeze the side panel
until it snaps securely into place.
7. Package the old CPU card for later.
• Put the used card into MACh Speed anti-static box. If you ever have a
problem, it may be handy to be able to use the old card while troubleshooting
the system.
8 Reconnect all cables and reboot your system. The installation is finished.

Key Commands for XLR8 MACh Speed Control
The MACh Speed Control Software includes a series of key commands and useful identifiers if the
problem is due to the card itself.
To disable the cache on boot-up:
• Depress the “shift” key on boot-up to disable extensions, or
• Depress “command-option-x-d” until the XLR8 extension is displayed.
To disable the cache during normal operation:
• Select “Disable” in the Manual settings of the Advanced tab in XLR8 MACh Speed Control
To retest the cache on boot-up: (the cache is tested on the first boot after changing the CPU speed)
• Depress “command-option-x-r” on boot-up until the XLR8 extension appears.
To disable the cache test on boot-up:
• Depress “command-option-x-d” on boot-up until the XLR8 extension appears.
Troubleshooting the MACh Speed ZIF card
If your computer does not power up (Three tones? Redo the Firware Patch!)
• Make sure the cables, video and/or other PCI cards are properly seated and connected.
• Check the MACh Speed ZIF card to see if it is properly and fully seated and that
the heat-sink is properly installed and seated on the CPU card.
• If your computer still does not power up, try removing and reinstalling the MACh
Speed ZIF card.
If your computer powers up, but freezes during startup
• ZAP the P-Ram. This is an area of memory on the motherboard that retains card
settings/date/motherboard devices/etc. To refresh/ZAP, depress the
“command-option-P-R” keys simultaneously, immediately after the boot chime (a second
chime should occur.)
• If you are still having problems, try starting up with extensions disabled. This will
also disable the backside cache on the upgrade card.
• If you system did not freeze when booting with extensions off, reboot holding the
Space Bar down. During the boot sequence the Apple Extension Manager dialog
will be displayed. Select Base OS settings, then scroll to re-enable the MACh Speed
Control. Press Continue. If you are able to boot at this point, you have a software
conflict. Reboot and re-enable extensions one at a time, until you find the conflict.
You can then change the first letter of the Extension's name to change its load
order, and usually fix the conflict.
• If you have installed a MACh Speed G4 ZIF MPe in a PowerMac G3 Blue&White,
make sure you have updated your Apple firmware to version 1.1 and applied the
XLR8 firmware patch before installing your upgrade card.
• Perform a “Clean Install” of your system software. You can select the “Clean Install” in the
option of the MacOS installer. Performing a clean install, does not delete your current
system folder, but will keep it on your hard drive with the name “Previous System Folder”

This section provides information on troubleshooting your system with the MACh Speed
ZIF upgrade and software installed. Additional Troubleshooting information is available
on the web at www.xlr8.com/support or www.xlr8.com/osc
Note that most problems associated with the MACh Speed ZIF Upgrade are usually related
to software conflicts or corruption that manifests itself only while running at the faster
speeds. To test a problem system, always attempt to return the system to its simplest config-
uration. Disable all unneeded software, and disconnect all optional devices.
