Install Software… FIRST
A. ALL USERS—Install or Upgrade to Mac OS 9.2, If
Necessary
This Encore/ST G4 Duet processor upgrade requires that Mac OS 9.2
be installed on your system on a writeable local hard disk (not a CD,
DVD or network disk). You must boot your system from a Mac OS 9.2
system folder in order to update and/or patch the Power Mac firm-
ware so your system can support this upgrade card. Verify the Mac
OS version on your system is at least Mac OS 9.2, and then install or
upgrade the OS software if necessary.
B. AGP Graphics, Gigabit Ethernet, and Digital Audio
Users Only—Update Power Mac Firmware
If your computer is a Power Mac G4 (QuickSilver) model, skip to section C
on page 2. Otherwise, before installing the Duet, you must ensure your
AGP Graphics, Gigabit Ethernet, or Digital Audio system’s firmware
has been updated to version 4.2.8. Please note, your system may need to
connect to the Internet to perform some of the steps.
1. OS 9 users: Select and open Apple System Profiler from the
Apple Menu. Click the triangle next to Production Information,
and find the Boot ROM version information
(Figure 1). If it reads
“ $0004.28f1”, skip the rest of the steps in this section and pro-
ceed to section C on page 2. Otherwise, go to step 2.
OS X users: Open System Profiler or Apple System Profiler (located
within the Utilities folder found in the Applications folder). Find
the Boot ROM information listed in the Hardware Overview
pane
(Figure 2). If it reads “4.28f1”, skip the rest of the steps in
this section and proceed to section C on page 2. Otherwise, go to
step 2.
2. Boot your system in Mac OS 9.2.x (the firmware updater will
not work in OS X Classic mode). As of this writing, Apple has not
made this firmware updater available as an OS X application.
3. Log on to the Internet and type the following in your browser
window’s address bar:
http://docs.info.apple.com/article.html?artnum=120068
4. Click on the appropriate link to download the firmware (Figure 3).
5. Double-click the G4 FW Update 4.2.8.smi file icon to mount
the G4 Firmware Update disk image. Double-click the G4
Firmware Update icon to open the disk image, then double-click
the About G4 Firmware Update file icon. Once the read me file
has opened, print it. Following the directions on the pages you
printed, update the firmware on your system.

WARNING: When you install (or upgrade to) Mac OS 9.2 or
later in an AGP Graphics, Gigabit Ethernet, or Digital Audio
model, you may have to upgrade your computer’s firmware as part of
the software installation. Please note, the firmware installed with the
Mac OS may not be the version required by the Duet. Before install-
ing the Encore/ST G4 Duet, you may be required to upgrade your
firmware again; you MUST ensure your system is using version
4.2.8 firmware. If your system is using an earlier version of the firm-
ware, your system will not operate with the Duet installed.
