A. AGP Graphics, Gigabit Ethernet, and Digital Audio
Users Only—Update Apple Power Mac Firmware
If your computer is a Power Mac G4 (QuickSilver) model, skip to sec-
tion B on page 2. Otherwise, before installing the Encore/ST G4, you
must ensure your AGP Graphics, Gigabit Ethernet, or Digital Audio
system’s original Power Mac firmware has been updated to the latest
version (currently 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 B 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 B on page 2. Otherwise, go to
step 2.
2. Boot your system in Mac OS 9.2 (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.
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 original Power Mac
firmware as part of the software installation. Please note, the firmware
installed with the Mac OS may not be the version required by the
Encore/ST. Before installing the Encore/ST G4, 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 firmware, your system will not operate with the Encore/ST G4
installed.
