3-2 Hardware Devices and Drivers Part 2

> Implement, manage, and troubleshoot input and output (I/O) devices.

To install a device Connect the device to the appropriate port or slot on your computer, according to the device manufacturer's instructions. You may need to start or restart your computer.

• You need administrative privileges if installing a device that requires a user interface or if you experience errors during the installation process.
• To add and set up a non Plug-and-Play device connected directly to your computer, you must be logged on as an administrator or a member of the Administrators group
• If an administrator has already loaded the drivers for the device, you can install the device without administrator privileges.
• If you need to start or restart your computer, Windows 2000 should detect the device and start the Found New Hardware wizard.

To install a non-Plug and Play device

• Open Add/Remove Hardware in Control Panel.
• Click Next, click Add/Troubleshoot a device, and then click Next.Windows 2000 attempts to detect new Plug and Play devices.
• If your device is not in the device list, click Add a new device.Click Next, and then do one of the following: Click Yes, search for new hardware if you want Windows 2000 to try and detect the new non-Plug and Play device you want to install. Click No, I want to select the hardware from a list if you know the type and model of the device you are installing and you want to select it from a list of devices.
• Click Next, and then follow the instructions that appear on your screen.

Monitor, configure, and troubleshoot I/O devices, such as printers, scanners, multimedia devices, mouse, keyboard, and smart card reader.

To Monitor, configure, and troubleshoot I/O devices

• Right click My Computer select properties
• Select Hardware Tab
• Click Device Manager button
• Then Click and select properties for the device you want to configure

Install, configure, and manage modems.

A modem is a device that makes it possible for computers to communicate over telephone lines. The word modem comes from Modulate and Demodulate. Because standard telephone lines use analog signals, and computers digital signals, a sending modem must modulate its digital signals into analog signals. The computers modem on the receiving end must then demodulate the analog signals into digital signals.

Modems can be external, connected to the computers serial port by an RS-232 cable or internal in one of the computers expansion slots. Modems connect to the phone line using standard telephone RJ-11 connectors.

Check Device Manager to see if the modem is listed and working properly if not reinstall drivers, if this does not work:

• Check for conflicting IRQ's
• Check port number
• Check that card is seated in the mother board properly

Install, configure, and manage Infrared Data Association (IrDA) devices.

Most internal IrDA devices are installed by Windows 2000 Setup or when you start Windows after adding one of these devices.

Installing an IrDA device if it was not installed automatically by Windows after restarting your computer.

1. Install the internal IrDA device or Attach the IrDA transceiver to the serial port.
2. Open Add/Remove Hardware.
3. Click Next.
4. Click Add/Troubleshoot a device, and then click Next.
5. In Devices, click Add a new device, and then click Next.
6. Click No, I want to select the hardware from a list, and then click Next.
7. In Hardware types, click Infrared devices, and then click Next.
8. In Manufacturers, click the manufacturer, and in Infrared Device, click the infrared device.
9. If you have an installation disk for the infrared device, click Have Disk.
10. Click Next, and then follow any additional instructions to install the device.

Install, configure, and manage wireless devices.

After an infrared device is installed, (see Above) the Wireless Link icon appears in Control Panel. When another IrDA transceiver comes in range, the Wireless Link icon appears on the desktop and on the taskbar. You can then send a file over the infrared connection with any of the following actions:

• Specify a location and one or more files using the Wireless Link dialog box.
• Use drag-and-drop operations to move files onto the Wireless Link icon on the desktop.
• Right-click any selection of files on the desktop, in Windows Explorer, or in My Computer, and then click the Send To Infrared Recipient command.
• Print to a printer configured to use an infrared port.

Wireless access points

A wireless network adapter card with a transceiver sometimes called an access point, broadcasts and receives signals to and from the surrounding computers and passes back and forth between the wireless computers and the cabled network.

Access points act as wireless hubs to link multiple wireless NICs into a single subnet. Access points also have at least one fixed Ethernet port to allow the wireless network to be bridged to a traditional wired Ethernet network.

Install, configure, and manage USB devices.

Universal serial bus is an external bus that supports Plug and Play installation, and port is usually located on the back of your computer near the serial port or parallel port.

USB ports have a separate entry in Device Manager. To check the device status, click Universal Serial Bus controllers, right-click USB Root Hub, and then click Properties. If USB is enabled in BIOS but the USB host controller does not appear in Device Manager under Universal Serial Bus controllers, or a yellow warning icon appears next to the host controller name, then the version of BIOS may be outdated, and needs to be updated.

When using USB devices you can:

• Connect and disconnect devices without shutting down or restarting your computer.
• A single USB port to connect up to 127 peripheral devices, including speakers, telephones, CD-ROM drives, joysticks, tape drives, keyboards, scanners, and cameras.

> Update drivers.

To update device drivers:

Open Device manager, from device manager select the device you want to update the driver for, then right click and select properties. Then select the Driver tab, and update driver button, and follow the wizard.

To update printer drivers:

• Open Printers.
• Right-click the printer, and then click Properties.
• On the Advanced tab, click New Driver to install a new or updated version of the printer driver using the Add Printer Driver wizard click next
• Click the appropriate printer manufacturer and printer model if the new or updated driver is on the list. Or Click Have Disk if the printer driver is not included in the list or if you have received a new or updated driver on CD or diskette from the printer manufacturer, type the path where the driver is located, and then click OK.
• Click Next, and then follow the instructions on the screen to finish installing the printer driver.

> Monitor and configure multiple processing units.

To upgrade from a uniprocessor to a multiprocessor computer:

• Open Device Manager.

• Click Next again, and then click Finish.

> Install, configure, and troubleshoot network adapters.

A network adapter (sometimes called a network interface card, or NIC) is a hardware card installed in a computer so it can communicate on a network. The network adapter provides one or more ports for the network cable to connect to, and it transmits and receives data onto the network cable.

Every networked computer must also have a network adapter driver, which controls the network adapter. Each network adapter driver is configured to run with a certain type of network adapter.

A networked computer must also have one or more protocol drivers (sometimes called a transport protocol or just a protocol). The protocol driver works between the upper-level network software and the network adapter to package data to be sent on the network.

In most cases, for two computers to communicate on a network, they must use identical protocols. Sometimes, a computer is configured to use multiple protocols. In this case, two computers need only one protocol in common to communicate. For example, a computer running File and Printer Sharing for Microsoft Networks that uses both NetBEUI and TCP/IP can communicate with computers using only NetBEUI or TCP/IP.

To add a network component

• Open Network and Dial-up Connections.
• Right-click the connection to which you want to add a network component, and then click Properties. Do one of the following: If this is a local area connection, click Install. If this is a dial-up, VPN, or incoming connection, on the Networking tab, click Install.
• In the Select Network Component Type dialog box, click either Client, Service, or Protocol, and then click Add.
• Do one of the following: If you do not have an installation disk for the component, click the appropriate client, service, or protocol, and then click OK. If you have an installation disk for the component, click the appropriate client, service, or protocol, click Have Disk, insert the installation disk into the selected drive, and then click OK.

The most common network adapter problems are interrupt conflict and transceiver setting.

Things to Check:

• Do the setting on the card match the setting in the network software you using
• Is there a conflict between IRQ's
• Is there an I/O address conflict
• Is there a memory conflict
• Is the cable attached securely
• Is the adapter card set to the correct speed setting for the network
