2 How to Install and Replace Components In Your Desktop PC  
Installing Accessory Boards  
8 The accessory board may need a special connection, such as:  
WOL (Wake on LAN) connector to the Network board.  
CD-ROM drive to the sound board (if you no longer want to use  
the integrated audio).  
Integrated Audio Connector  
If you install an add-on sound  
board, remove the cable in this  
connector and insert it into the  
sound board’s connector.  
WOL Connector  
For more information, refer to the documentation that came with  
the accessory board. The necessary cables are usually provided with  
the accessory board.  
NOTE  
If you install a network board and connect it to the WOL connector, you  
must enable the Suspend Wake-Up/Integrated Networkand/or  
Integrated Networkfields in the Powermenu of the PCs Setup  
program. This only applies if the network board supports these modes.  
To enter the Setup program, press F2 during startup.  
If you install an add-on sound board (and you no longer want to use the  
integrated audio), you must set the Integrated Audio Interfacein  
the Advancedmenu of the Setup program to Disabled.  
9 Replace the cover (described in this chapter).

2 How to Install and Replace Components In Your Desktop PC  
Installing Accessory Boards  
Configuring Accessory Boards with Plug and Play  
Plug and Play is an industry standard for automatically configuring  
your PC's hardware resources and the accessory boards installed in it.  
Your PC has configurable support for Plug and Play in the BIOS.  
All PCI accessory boards are Plug and Play, although not all ISA boards  
are. Check the accessory boards documentation if you are unsure.  
When you start your PC after installing an accessory board, the Plug  
and Play BIOS automatically detects which hardware resources (IRQs,  
DMAs, memory ranges, and I/O addresses) are used by PC components  
(such as the keyboard, the communications ports, network adapters,  
and accessory boards).  
Windows 95 and  
Windows 98  
Operating systems that support Plug and Play, such as Windows 95 and  
Windows 98, will automatically detect a newly installed Plug and Play  
accessory board and install the driver for this device, if the driver is  
available.  
Windows NT 4.0  
For operating systems that do not support Plug and Play, such as  
Windows NT 4.0, refer to the operating system documentation for  
information about installing accessory boards.  
In Windows NT 4.0, click the Start button then click Help. You can  
use the contents or index to find information about installing devices.  
Windows NT 4.0 helps you through the installation of devices such as  
modems and sound boards.  
NOTE  
After installing a new device in Windows NT 4.0, you must re-install the  
Microsoft Service Pack to update the operating system for your PC.  
To do this, click the Start button then select Programs – Windows  
NT Update.  
69  
2 How to Install and Replace Components In Your Desktop PC  
Installing Accessory Boards  
Configuring non-Plug and Play ISA Accessory Boards  
If you install an ISA accessory board that is not Plug and Play, you will  
need to configure the board before your PC can use it. For instructions  
about configuring the board, refer to the documentation that came  
with the board.  
For guidelines on available IRQs and I/O addresses in your PC, refer to  
page 119. Some operating systems, such as Windows 95, can display  
the IRQs and I/O addresses currently used by your PC. Refer to the  
operating system documentation for more information.  
Refer to the documentation supplied with the operating system for  
details on your operating systems capabilities and restrictions  
concerning non-Plug and Play accessory boards.  
Resetting the PC’s  
Configuration Data  
If your PC is having difficulty recognizing the ISA board, try resetting  
the PCs data configuration. This will clear any old configuration data  
that is no longer used. To do this, enter the PCs Setup program, set the  
Reset Configuration Data parameter to Yes, and restart the PC.  
To enter the Setup program, press F2during startup.
