Installing and Configuring Software

When you obtain software, check it for viruses with virus-scanning software before installing it on your computer's hard drive. Viruses, which are pieces of
code that can replicate themselves, can quickly use all available system memory, damage or destroy data stored on the hard drive, and permanently affect the
performance of the programs they infect. Several commercial virus-scanning programs are available for purchase, and most bulletin board services (BBSs)
archive freely distributed virus-scanning programs that you can download with a modem.
Before you install a program, read its documentation to learn how the program works, what hardware it requires, and what its defaults are. A program usually
includes installation instructions in its accompanying documentation and a software installation routine on its program diskette(s) or CD(s).
The software installation routine assists you in transferring the appropriate program files to your computer's hard drive. Installation instructions may provide
details about how to configure your operating system to successfully run the program. Always read the installation instructions before running a program's
installation routine. You may be instructed to modify some operating system start-up files, such as config.sys and autoexec.bat, or the installation routine
may modify start-up files automatically.
When you run the installation routine, be prepared to respond to prompts for information about how your computer's operating system is configured, what
type of computer you have, and what peripherals are connected to your computer.
TAPI
Telephony Application Programming Interface (TAPI) enables Windows-based applications to operate with a wide variety of telephony devices, including voice,
data, fax, video, and so forth. TAPI applications require a TAPI service provider (TSP), which is a software driver that allows TAPI applications to communicate
with different types of TAPI hardware.
Microsoft® Windows® 2000, Windows XP, and Windows NT® provide a TSP called Unimodem, which is a "universal" modem service provider that supports a
wide range of commonly used modems. For more information on Unimodem, see your Windows documentation. When using a TAPI device other than a
modem, such as a Private Branch Exchange (PBX) or a voice processing card, you will need a TSP provided by the manufacturer of the device.
The TAPI system board connector uses a 4-pin cable to interface your internal TAPI-compliant expansion card with the audio system in your computer. To
locate the TAPI system board connector, see
example, you can connect your modem to the TAPI connector and then use your audio speakers and microphone as a speakerphone. The microphone carries
your voice into the computer and then through the TAPI system board connector to your modem card. The caller's voice enters through the modem card to the
TAPI system board connector and then out to the speakers. You can also use this configuration to record and play sound files over the phone.

Installing a TAPI Device

CAUTION: Before you perform this procedure, see
1. Turn off the computer and peripherals, disconnect them from their electrical outlets, wait at least 5 seconds, and then
"System Board Components." TAPI-compliant cards using the standard TAPI connector are supported. For
