Sonnet Technologies Crescendo_7200 Processor Upgrade Card - Manual (Page 2)

Figure 1
Install Mac OS 9 or 9.1 (if necessary)
If you are upgrading to Mac OS 9.x as part of this installation, do so now. Please
note, however, it is not necessary to upgrade to Mac OS 9 to take advantage of the
Crescendo’s features and speed. If you are not upgrading your Mac OS software at
this time, skip to the next section, “Install Sonnet Software.”
1. Start up your computer from the Mac OS 9.x CD and double-click the Mac
OS Install icon. In the Select Destination window, click the Options button
and click the Perform Clean Installation check box that appears in the subse-
quent screen. Click the Select button. Proceed through the next several
screens until you reach the Install Software window. Click OK, Start, then
Continue, and complete the installation. After the software is installed, quit
the Mac OS Install application and restart your computer from the hard
drive where Mac OS 9.x is installed
Install Sonnet Software
You must install the Sonnet software before you install the Crescendo/7200.
Otherwise, your computer will not operate with the Crescendo/7200 installed.
1. If you are now using Mac OS 8.6 or later, proceed to step 3.
Otherwise, log onto the internet and type in the following:
www.sonnettech.com/support/crescendo7200. Read the information on the
page, then click on the link to download the ASP 2.1.2.smi (Apple System
Profiler) file.
2. Install the Apple System Profiler software.
3. Open Apple System Profiler from the Apple menu. Select the System Profile
tab, then click on the arrow next to Memory overview. Click on the arrow next
to Built-in memory and look at the information listed under Location and Size;
write down this information (Figure 1). Confirm that your system will meet
the memory requirements for the version of operating system software you
are using (Figure 2).
4. Insert the Crescendo/7200 Install diskette into the floppy disk drive. Double-
click the Crescendo/7200 Install icon. Review the Read Me screen for any
known configuration issues with the current software release. By default,
with “Easy Install” selected from the pop-up menu, the required software will
be installed into the active System Folder on the boot drive. If this is ok, click
the Install button; otherwise, select “Custom Install” from the pop-up menu
for more options or select another drive to install the software. The installer
will install the appropriate software into the System Folder of your computer.
If the installation was successful, a dialog box will appear. Click Quit to leave
the installer, then shut down your computer.

Apple’s website and installing it in your system, but only if you are using a version of
Mac operating system software prior to Mac OS 8.6. The application, Apple System Profiler

You do not have to download and install this software, but you may not be able to determine
whether your system meets the memory requirements until after you have opened the
computer.
