Crescendo Installation
Identify System Video Output Configuration
Before installing the Crescendo card into your computer, it is important
to identify your system configuration for video output.
Apple manufactured the Power Macintosh 8100 with an AV (Audio/
Video) card or HPV (High Performance Video) card installed in the PDS
slot of the computer. Other video alternatives include onboard video
through the high density video port or a NuBus video card.
Determine your video output configuration by referring to Figure 1
below. There are three possible configurations:
• Apple AV or HPV Card – If the monitor is attached to a card
installed in the PDS slot (Figure 1-Label B), you have an AV or
HPV card. Since the Crescendo card installs into the PDS slot, you
will need the AV/HPV Card Video Adapter Kit (Sonnet part number
C61A-7181) to preserve the use of the AV or HPV card. If you
purchased a video adapter kit, continue with the installation on the
following page; otherwise, contact Sonnet or a Sonnet reseller to
obtain one.
• Onboard Video – If the monitor is attached to the high density
video port (Figure 1-Label A), you have onboard video. Continue
with the installation on the following page.
• NuBus Video Card – If the monitor is attached to a card installed in
one of the three NuBus slots (Figure 1-Label C), you have a NuBus
video card; continue with the installation on the following page.
