in a 5400 Series Macintosh Computer
This chapter describes how to install the PC Compatibility Card hardware in
a 5400 series Macintosh computer, such as the Macintosh Performa 5400,
Macintosh Performa 5420, and the Power Macintosh 5400.
IMPORTANT
Card hardware is already installed. Skip ahead to “Connecting Another
Monitor to a 5400 Series Macintosh Computer” later in this chapter. If you
want to install additional memory on your card or learn more about installing
and using PC software, see the PC Compatibility Card User’s Manual.

What you need
Before beginning the installation process, make sure you have all the parts
and tools that are necessary to install the card in your computer. To install the
card in a 5400 series Macintosh computer, you need the PC Compatibility
Card, the internal PC audio/video assembly, and the cable clamp. You also
need a Phillips screwdriver.

The Apple External Video Connector and the PC Compatibility Card cannot
be installed together into a 5400 series Macintosh computer. If your
computer has the video connector shown below, you will have to remove it
during the installation of the PC Compatibility Card.
If this connector is present, then an Apple External
Video Connector is installed in your computer.
Instructions for removing the Apple External Video Connector are included
in the installation instructions that follow.

Installing the PC Compatibility Card hardware
There are several steps to installing your PC Compatibility Card hardware:
m opening the computer
m removing the Apple External Video Connector if there is one installed
m installing the card
m installing the internal PC audio/video assembly
m closing the computer
Opening the computer
IMPORTANT
To avoid generating static electricity that may damage
components, do not walk around the room until you have completed the
installation of the PC Compatibility Card and closed the computer.
Additionally, move the logic board as little as possible while it is outside the
computer case.
1Shut down the computer.
2 Press the power switch on the back of the computer to turn it completely off.
Press the side of the switch marked with the j symbol.
3Unplug all the cables except the power cord from the computer (including the cable that
connects your keyboard to the computer).
Note: Leaving the power cord plugged in helps protect the computer from
damage caused by electrostatic discharge.

7Connect the PC Compatibility Card and the PCI card adapter.
Place the adapter on top of a magazine on a firm surface. (Make sure the
magazine is thick enough to protect your working surface from being
scratched by the metal pins on the adapter.)
Press the card firmly into the adapter. You may find it helpful to place the
card and the adapter near the edge of a table with the metal edge of the card
hanging over the end of the table. In this position, you can easily insert the
card completely into the adapter.
Place the adapter on
top of a magazine on
a firm surface.

4Fold the slack in the internal PC audio/video assembly cable into the shape of a Z on top
of the card. Firmly pinch the two new folds so that the cable lies flat along the top of
the card.
IMPORTANT
Do not press down too hard on the top of the card. Applying
excessive pressure to the card may damage the card and your logic board.
Once you have folded the slack in the cable into a loose Z shape on top of the
card, firmly pinch the new folds in the cable so that it lies flat.

You are now finished installing the card.
Reminder: When you turn on your computer, don’t forget to open the control
panels for the date and time, keyboard, and mouse to make sure that they are
set the way you want them. (Pressing the reset button on the logic board
changed these settings.) For more information about working with control
panels, see Macintosh Guide, the on-screen help that’s available in the
Guide (h) menu.
Connecting another monitor to a 5400 series Macintosh computer
You can display both the PC environment and the Mac OS environment on
the monitor that is built in to a 5400 series Macintosh computer. You can also
connect another monitor to display both environments simultaneously.
If you connect another monitor, you see the Mac OS environment on the builtin monitor and the PC environment on the other one. You can connect any
Macintosh- or PC-compatible monitor (with the proper cable adapter, available
from your monitor vendor or Apple-authorized dealer or service provider).
To connect another monitor, plug the middle connector on the loopback cable
into the port on the PC Compatibility Card. Then connect the monitor cable
to the short end of the loopback cable.
26
Chapter 1
Note: If you want to use a multiple-scan monitor from a manufacturer other
than Apple to display the PC environment, you also need to use a VGA-toMacintosh adapter (available from your computer vendor). Connect this
adapter between the monitor’s cable and the loopback cable.
WARNING
Do not plug a monitor into the joystick port that comes on
some models of the PC Compatibility Card, and do not plug a joystick
into a monitor port (marked with the icon ™). Serious damage can
result to your equipment.
