Chapter 3 - MACh Speed G3 Control Software
About MACh Speed G3
Control software
XLR8’s MACh Speed G3 software provides full compatibility
with all major third-party hardware. This new fully automatic
version of the XLR8 software transparently tests the cache on
start-up and configures your G3 for optimal operation.
• Virtual Firmware
™
-- The new 1.3 version of the soft-
ware uses an exclusive technique known as Virtual
Firmware. This technique allows compatibility soft-
ware to be loaded into the system before "non-G3"
hardware is initialized. Unlike other early loading
compatibility software, soft "zapping" of PRAM or
booting without extensions does not flush Virtual
Firmware.
• MVP
™
-- Like all XLR8 CPU upgrades, this new
software fully supports XLR8’s exclusive MVP
(Multiple Variable Processing) technology. This
technology allows the user to modify RAM-to-CPU
bus speed, the CPU multiplier, and the CPU-to-cache
bus speed for optimized system performance.

Installing MACh Speed G3
Control software
Installation of the MACh Speed G3 Control software is fully
automatic. Installing the software prior to installing the G3
processor upgrade is highly recommended.
Pre-loading the software allows the Virtual Firmware
™
to be
initialized, and removes other G3 control panels and system
extensions that may cause incompatibilities.
The installer will place an extension file in the System
Extension folder; a control panel in the Control Panel folder,
a series of useful files in an XLR8 Folder, and will place all
old, or possibly incompatible G3 software packages in a
recovery folder.
Install the software:
• After booting your Macintosh, insert the XLR8
CD-ROM and open the G3 Control folder.
• Review the ReadMe file on the disk for any last
minute changes or updates.
• Launch the Installer program by double-clicking the
MACh SpeedG3 icon .
• Read the text and follow the on-screen instructions
until you have completed the installation.
• Restart your computer.
• Provided that your system reboots correctly, you are
now ready to use G3 Control. If you have any problems
rebooting, refer to Chapter 6, Technical Support.
