Installing the PC Compatibility Card

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 If you received this manual with a computer, the PC Compatibility 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’ 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:

mopening the computer

mremoving the Apple External Video Connector if there is one installed

minstalling the card

minstalling the internal PC audio/video assembly

mclosing 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.

2Press 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.

9Insert the adapter into the PCI slot on the main logic board. Make sure the metal fence on the PC Compatibility Card engages the hook on the vertical plate and that the connectors on the card protrude through the PCI access port opening.

The card is properly seated when the card’s metal “fence” engages this hook on the vertical plate.

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.

7Plug the cables back into the computer.

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 Macintoshor 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.

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-to- Macintosh 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 ª). Serious damage can result to your equipment.
