Power Management Features

The system comes with Advanced Power Management (APM) and Advanced Configuration and

Power Interface (ACPI). Included as a subset to ACPI is Instantly Available Technology.

APM features Soft Power Off, which automatically powers down the system when exiting

Windows 98 or Windows 2000 (not available for Windows NT). This feature is enabled or disabled through the system’s BIOS (see Section 2, “System Configuration,” for Power

Management BIOS settings).

Instantly Available Technology features the ACPI sleep mode which maximizes power savings.

When in the sleep mode, the system appears to be off. The power supply and fans are off and the power lamp is amber. Pressing a key or moving the mouse instantly wakes up the system and returns it to where it was before going into the sleep mode. This feature is enabled or disabled by setting jumpers on the system board (see Section 2, “System Configuration” for information on setting system board jumpers).

If the system has an optional internal or external modem installed, the Wake On Ring (WOR) and Resume On Ring (ROR) features of the system can be used. With WOR, the system can be powered up through the modem from either the Soft Power Off or ACPI modes. The first call through the modem powers on the system and the second call allows access to your system.

The ROR feature allows a single call on the modem to resume system operation and to allow system access. The ROR feature can be used while the system is in the sleep mode or the ACPI power on state.

See Section 2, “System Configuration” for information on setting the WOR and ROR features through the system’s BIOS. In addition, for the WOR feature, a cable must be connected to a modem and to the WOR connector on the system board.

Security Features

The system has hardware, software, and mechanical security features that offer protection against unauthorized access to the system and data. The following security features are available.

Password Security

The BIOS Setup Utility includes a feature that allows a user to set either a user or supervisor password, or both.

The user password controls booting of the system and controls access to the Setup Utility and the keyboard. User access to the BIOS Setup Utility is limited when a supervisor password is set. The supervisor password allows full access to the system and the BIOS.

See Section 2, “System Configuration,” for further information on setting and using passwords.

Windows Network Security Features

The Windows Network Security feature is available through the Windows operating system.

Check the Windows documentation for details.

Keyboard/mouse Anti-theft Bracket

The keyboard/mouse anti-theft bracket secures the keyboard and mouse cables to the system, making it difficult to remove the keyboard and mouse from the system.

Locking Tab

The system has a locking tab on the rear of the system. The tab fits through a mating slot in the rear edge of the chassis cover. Securing a padlock (not supplied) in the locking tab prevents removal of the system cover and access to the interior of the system.

Chassis Intrusion Notification

Whenever the system cover is removed, a hidden switch (if installed) sends a signal to the

LANDesk Client Manager (LDCM). LDCM logs the incident and then reports it on screen the next time the system is rebooted.

Hard Drive Password Protection

The system supports password protection for the hard drive. Hard drive password protection restricts access to the drive if the drive is removed and installed in another system. The system does not prompt for hard drive passwords while the drive remains in the current system.

The passwords are written to the system BIOS and to the hard drive to ensure that the password protection travels with the drive if it is moved to another system. See Section 2, “System

Configuration,” for additional information on using hard drive security.

Your system ships from the factory with the correct system parameters for your configuration.

Unless you add optional hardware, you do not need to run the BIOS Setup Utility to operate the system. However, you might wish to run the BIOS Setup Utility to set features that customize the system, such as security features.

NECC recommends that you print out or write down the current BIOS Setup parameters and store the information in a safe place. This lets you restore the system to the current parameters if you need to replace the CMOS battery (see “CMOS Battery” in Section 3).

How to Start Setup

To start the BIOS Setup Utility, follow these steps.

1. Turn on or reboot the system.

2. Press F2 at the NEC startup screen ( F2 appears on the bottom of the screen). You have about five seconds to press F2 .

Setup’s Main Menu window appears similar to the following screen.

Note

The following screen is a typical screen for a system with a 10.0-GB hard drive. The actual settings on the menu screen depend upon the hardware installed in the system.

Hard Drive Security

The NEC PowerMate CT system allows establishing password protection for the internal hard drive. Hard disk drive (HDD) password protection restricts access to the drive only if the drive is removed from the PowerMate CT system and installed in another system. The system does not prompt you to enter your HDD passwords while the drive remains in the current system.

The HDD passwords are written to the system BIOS and to the hard drive to ensure that the password protection travels with the drive if it is moved to another system.

Establishing Hard Disk Drive Passwords

To establish password protection for the system’s hard drive, you must establish a master password, establish a user password, and enable the established passwords for the internal hard drive. Use the following procedure to establish HDD passwords and to enable HDD password protection.

If you set the master and user password on a hard drive, you can never remove the passwords. You can change the passwords. If you forget the master password and install the drive in another system, you cannot access the data on the hard drive.

Once you set these passwords, NEC Computers Inc. has no capability of removing them.

If you install the hard drive in another PowerMate system with hard disk drive security enabled, you must enter the password to allow access to the hard drive. If this PowerMate system does not support hard disk drive security, you cannot access the data on the hard drive.

1. Boot your system. Press F2 when prompted to enter BIOS Setup. The Main Menu screen appears.

2. Using the arrow keys, select the Security Menu.

3. Use the down arrow key to highlight Assign HDD Password and press Enter . The system prompts you to enter a master password.

4. Enter a master HDD password and press Enter . The system prompts you to reenter the password to verify.

5. Reenter the master HDD password and press Enter . The system confirms the creation of the master password and prompts you to enter a user password.

6. Enter a user password and press Enter . The system prompts you to reenter the password to verify.

7. Reenter the user password and press Enter .

8. Highlight and select Primary Master HDD Password . Use the + (plus) and – (minus) keys to enable the selection. (This enables password protection for the internal HDD.)

Changing Hard Disk Drive Passwords

Use the following procedure to change hard disk drive passwords.

1. Boot your system. Press F2 when prompted to enter BIOS Setup.

2. At the Main Menu screen, select the Security Menu.


3. Highlight Assign HDD Password and press Enter .

!

If you enter the current master password, you are prompted to enter a new master password.

!

!

If you enter the current user password, you are prompted to enter the new user password.

If you do not want to establish a new master or user password, press Esc instead of entering a new password.

4. Save the changes and exit BIOS Setup.

Using Hard Disk Drive Password Protection

To facilitate the transfer of one or more HDDs between systems, establish a single master password (and store the password in a secure place). Forgetting the master password results in the inability to access the data on the hard drive. Establish different user passwords to limit access to specific systems.

If you set the master and user password on a hard drive, you can never remove the passwords. You can change the passwords. If you forget the master password and install the drive in another system, you cannot access the data on the hard drive.

Once you set these passwords, NEC Computers Inc. has no capability of removing them.

If you install the hard drive in another PowerMate system with hard disk drive security enabled, you must enter the password to allow access to the hard drive. If this PowerMate system does not support hard disk drive security, you cannot access the data on the hard drive.

With hard disk drive security enabled on the original NEC PowerMate CT system, the system boots normally.

If you install the hard drive in another NEC PowerMate system with security enabled, you must enter the master password to access the hard drive. If the hard drive is installed in another NEC

PowerMate CT system with security disabled, the system prompts you to enter the master password and then a new user password.

Moving the Hard Drive

When a password protected hard drive is moved from its original system and installed in another system, error messages appear indicating that the drive is locked. Next, the Security Setup screen appears requiring the user to enter the master password to unlock the drive. Enter the master password, when prompted.

To take advantage of HDD password protection in another system, the system must be equipped with the same HDD password protection feature. To determine if the system has HDD password protection, check the Security Menu in the BIOS Setup to see if there are provisions for establishing HDD passwords.


FLASH Utility

The system BIOS resides on a flash read only memory (ROM) chip in your system. The FLASH

ROM can be updated using the following procedure. Before starting the BIOS update, NECC recommends that you first contact NECC for assistance (see Section 8 for contact information).

Update the FLASH ROM with a BIOS FLASH diskette. The diskette contains the latest version of the BIOS code. You can get the diskette from NECC or download the BIOS from the NECC website. See Section 8 for download and website information.

Update the BIOS from the BIOS FLASH diskette as follows.

1. Write down the BIOS Setup parameters currently set on your system.

2. Turn off the system.

3. Put the flash diskette in drive A, and turn on the system.

4. When the flash upgrade menu appears, choose Update Flash Memory Area from a file .

5. When the menu asks you to enter a path/filename, use the arrow keys to select the “.bio” file and press Enter .

6. The utility asks for confirmation to load the new flash into memory. Select Continue with

Programming .

7. After the upgrade completes, remove the diskette.

8. Reboot the system and start the Setup program. Press F9 to reset the BIOS defaults. Use the recorded Setup selections you made at the beginning of this procedure to set the parameters.

Intel Processor Serial Number Control Utility

The Intel Processor Serial Number Control Utility is a Windows program that enables or disables the reading of the Pentium III processor serial number by software. This function lets you control which software programs or websites have permission to read the processor serial number. When installed, the utility runs automatically each time the system powers on.

Note

The Intel Processor Serial Number Control Utility is for use with systems shipping with the Intel Pentium III processor. Installing this utility on a system that does not contain a

Pentium III processor generates an error message.

This utility places an icon in the Windows system tray. The icon provides a visual status of the processor serial number. You have the option of hiding the system tray icon. You can enable or disable the processor serial number at any time. However, enabling the serial number requires restarting the system.

System Requirements

!

!

!

The Intel Processor Serial Number Control Utility requires: a Pentium III processor-based system

Windows 98, Windows 2000, or Windows NT 4.0 (or later)

2 megabytes of hard drive space.

Installation

The Intel Processor Serial Number Control Utility (version 1.0) comes already installed on the system. The system ships with the processor serial number feature turned off.

Processor Serial Number

The Intel processor serial number, a feature of the Pentium III processor, is an identifier for the processor. The processor serial number is unique, and when used in conjunction with other identification methods, can be used to identify the system or user. This number can be used in a wide variety of applications that benefit from stronger forms of system and user identification.

The processor serial number is analogous to a conventional serial number, with these important differences:

!

A software application can read the processor serial number.

!

You can enable or disable the reading of the serial number via utility programs such as this one, or via the BIOS, depending on the system configuration.

For additional information about the Pentium III processor and the processor serial number, visit

www.intel.com/pentiumiii.

Frequently Asked Questions

What are the benefits of the processor serial number?

You can use the processor serial number in applications that benefit from stronger forms of system and user identification.

Why would I want to turn off my processor serial number?

Intel believes the processor serial number can provide compelling benefits to users. They are developing features in conjunction with the processor serial number to allow responsible service providers to provide services that maintain your privacy. However, if you are concerned that a given application/service using your processor number might impact your privacy, you can turn off the processor serial number using the utility.


What is the default state of the processor serial number?

The default state of the processor serial number is on, until the Processor Serial Number Control

Utility is installed. Once the Processor Serial Number Control Utility is installed, it turns the processor serial number off by default. You can use the utility to turn on the processor serial number.

Can a website read my serial number without my knowledge?

No, generally not. Websites cannot read serial numbers unless you allow them to download a program that can read the processor serial number. Almost all browsers are configured to warn users whenever they download executable software. Unless you disable the warning in the browser, you should receive a notification.

Does Intel track serial numbers?

Generally not, other than related to the manufacturing process. Intel does not, in the absences of advance and express consent of a user, collect serial number data that is otherwise identified with a user.

Which programs and/or websites currently use the processor serial number?

You can find a complete list of programs that can take advantage of the processor serial number and other new capabilities of the Pentium III processor at ttp://www.intel.com/pentiumiii/utility.htm

.

!

!

How can I tell if my processor serial number is turned on?

The vast majority of Pentium III processor-based systems ship with the processor serial number enabled. The control utility allows you to check the status by:

Viewing the icon itself. The disabled icon shows a red circle with a white “x.”

Clicking the task tray icon and selecting the “Status” menu item. Or you can select the menu from the tool tip shown when you position the mouse over the task tray icon.

5 1/4-Inch Accessible Devices

!

!

!

!

The chassis is designed so devices within it are easy to install and remove. Note these guidelines before installing or removing a 5 1/4-inch device.

!

!

Special rails are used on 5 1/4-inch devices that allow them to be easily inserted and removed.

The rails are designed to be stored in an empty bay when they are not attached to a device.

The bay cover cannot be secured over an empty bay if the bay has no rails.

Always place a bay cover over an empty bay.

NECC recommends that you always keep the rails if you remove a device from the system.

Use your stored rails on a new device if it doesn’t have the correct type of rail.

When you convert the chassis to a desktop or a minitower, always move the stored rails for the new position as well.

For procedures on removing or replacing rails, covers, or devices, see the following sections:

!

“Removing or Replacing a Bay Cover”

“Storing and Retrieving Unused Rails”

“Removing or Installing Device Rails”

“Removing a 5 1/4-Inch Accessible Device”

“Installing a 5 1/4-Inch Accessible Device.”


Removing or Replacing a Bay Cover

If the system has an empty 5 1/4-inch device bay, it is covered with a special bay cover. This cover physically protects the inside of the chassis, and its metal shielding also offers EMF protection.

See the following sections for information on removing or replacing a bay cover.

Removing a Bay Cover

Remove a bay cover as follows.

1. Remove the system cover and front panel, if not already removed (see “System Covers”).

2. Press the tabs on either side of the cover toward each other until they are released from their slots. The tabs are at the end of the rails inside the chassis.

3. Still holding the tabs, slowly slide the cover out along the rails. As soon as the cover is free of the chassis, the cover and the rails disassemble.

Removing a 5 1/4-Inch Device Bay Cover

4. Use these rails on the new 5 1/4-inch device if its rails are the wrong type (see “Removing or Installing Device Rails”).

If the device already has the right type of rails, set aside the rails you just removed for future use.

Note

Always keep unused rails; the bay cover cannot be replaced if there are no rails within the bay.


Replacing a Bay Cover

Replace a bay cover on a bay as follows.

Note

Place unused rails back in the empty bay before attempting to replace a bay cover. The bay cover cannot be secured over the bay if the rails are absent.

1. If necessary, put the rails back in the bay. The cover cannot be secured if there are no rails within the bay. (See the next section, “Storing and Retrieving Unused Rails.”)

2. Position the cover so the arrows on either side point up for the chassis orientation you are using.

3. Line up the cover tabs with the slots on the rails. These slots are about 1/4 inch in from the ends of the rails (see the following figure).

4. Place each cover tab in its slot.

Replacing a Bay Cover

A – Slot on Rail

B – Tab on Bay Cover

C – Bay Cover

Note: Rails are shown partially out of the system in this figure to show in detail the tabs at the end of each rail; make sure rails are fully inserted before attaching a bay cover.

Storing and Retrieving Unused Rails

The device rails on the 5 1/4-inch devices in the system are designed specially for the chassis. If the system has an unused 5 1/4-inch bay, there should be rails stored within it. Use these rails on new devices (if necessary). If you remove an old device, remove the rails and store them. If there is an empty 5 1/4-inch bay, store the rails in the chassis; otherwise set the rails aside for future use.

To store a rail in an empty bay:

The system power must be off before removing the cover and

2. Remove the system cover (see “System Covers” in Section 3).


3. Locate the jumper on the system board (see the preceding figure, “System Board Jumper

Locations”).

4. Remove any subassemblies blocking access to the jumper (see Section 3, “Disassembly and

Reassembly,” for procedures).

5. Change the jumper setting by moving the jumper to or from the pins as indicated in the jumper settings tables (see “System Board Jumper Settings” in Section 2).

For some functions, a jumper is moved or removed for only a few seconds. The jumper change takes effect immediately, even if the jumper is moved back to its original setting. Check the jumper settings tables carefully and be sure to move the correct jumper so you don’t inadvertently change important settings.

6. Replace any removed disassemblies and the system cover (see Section 3).

7. Connect any peripherals and power cords and power on the system.

Upgrade Sockets

The system board has the following upgrade sockets:

!

C – RIMM 2 Socket


Processor Socket

The processor installs in a 370-pin Socket 370 on the system board. The processor is held in place in the socket by a locking lever attached to the socket and a removable retention clip. The retention clip anchors both the processor and the processor heat sink to the Socket 370.

To remove or install a processor, see Section 3, “Disassembly and Reassembly.”

RIMM Sockets

Memory upgrades are installed into two memory module sockets on the system board. The sockets support up to 512 MB of high-speed memory. The system supports 184-pin, 800-MHz

RDRAM modules in 64-, 128-, and 256-MB unbuffered memory configurations.

Use the following guidelines for selecting and installing RIMM modules:

!

!

RIMM modules can be installed in one or two sockets if installing a RIMM module in only one socket, a continuity module must be installed in the second socket


!

the size of the RIMMs can vary between sockets but the memory operates at the speed of the slowest module

!

!

for sample memory configurations, see the following table, “Sample RIMM Upgrade Paths” to determine the memory you need for a memory upgrade, see “Checking System Memory” later in this section

!

to locate memory module sockets on the system board, see the previous figure, “System

The BIOS provides Power-On Self-Test (POST), system Setup program, PCI auto-configuration utility, and BIOS recovery code.

The FLASH ROM allows fast, economical BIOS upgrades. The FLASH ROM is a reprogrammable EPROM containing both the system and video BIOS. Using the FLASH ROM to change the ROM BIOS provides the following advantages:

!

BIOS upgrade is performed quickly and easily

!

expense of replacing ROM BIOS chips is eliminated, so system maintenance costs are reduced

!

less chance of inadvertently damaging the system board than when physically replacing

ROMs

!

network administrators can exercise company-wide control of BIOS revisions.

The BIOS programs execute the Power-On Self-Test (POST), initialize processor controllers, and interact with the display, diskette drive, hard drives, communication devices, and peripherals. The system BIOS also contains the Setup Utility.


The FLASH ROM allows the system and video BIOS to be upgraded with the BIOS Update

Utility, without having to physically remove the ROM (see Section 2 for further information on the BIOS Update Utility). The FLASH ROM supports the reprogramming of the system BIOS and the video BIOS.

System Memory

The system comes with between 64 MB and 512 MB of RDRAM installed in two RIMM sockets on the system board.

The RIMM sockets accept 184-pin, 64-, 128-, and 256-MB RIMMs. See the “Sample RIMM

Memory Upgrade Paths” earlier in this section for a list of supported RIMMs.

Plug and Play

The system comes with a plug and play BIOS in support of plug and play technology. Plug and play simplifies setup procedures for installing plug and play expansion boards. With plug and play, adding a plug and play expansion board is done by turning off the system, installing the board, and turning on the system. There are no jumpers to set and no system resource conflicts to resolve. Plug and play automatically configures the board. (Some plug and play devices might need to be jumpered if used in a system running the Windows NT operating system.

PCI/IDE Ports

The system board has two high-performance PCI/IDE ports: a primary port and a secondary port. The primary PCI/IDE port has an enhanced IDE interface that supports PIO Mode 4 devices with 66 MB per second maximum burst rate data transfers on the high-performance

Ultra DMA bus. The primary port supports Ultra DMA/66.

The installed hard drive is connected as a master device on the primary PCI/IDE port. The installed CD-ROM drive or DVD-ROM drive is connected to the secondary PCI/IDE port as a master device. The hard drive is connected to the primary port with a three-connector Ultra

DMA/66 40-pin, 80-conductor cable. The CD-ROM or DVD-ROM is connected to the secondary port with a standard three-connector IDE cable.

Parallel Interface

The system has a 25-pin bidirectional parallel port on the system board. Port specifications conform to the IBM-PC standards. The port supports Enhanced Capabilities Port (ECP) and

Enhanced Parallel Port (EPP) modes for devices that require ECP or EPP protocols. The protocols allow high-speed bi-directional transfer over a parallel port and increase parallel port functionality by supporting more devices.

The BIOS has automatic ISA printer port sensing that works with most devices. If the BIOS detects an ISA printer port mapped to the same address, the built-in printer port is disabled.

(Verify in the BIOS Setup that printer ports mapped to the same address are enabled or disabled appropriately.) The BIOS also sets the first parallel interface port it finds as LPT1 and the second port it finds as LPT2. The interrupt is set at IRQ7 via the BIOS Setup Utility. Softwareselectable base addresses are 378h, 278h, and 3BCh.

Sets of I/O addresses for the parallel port are given in the following table (see Section 2,

“System Configuration,” for interrupt levels). This is a list of all possible configurations; the parallel port uses only one set.

Parallel interface signals are output through the system board’s 25-pin, D-subconnector. The connector is located at the back of the system unit.

Serial Interface

The system has two 16C550 UART compatible serial ports (COM1 and COM2) integrated on the I/O controller. The serial ports support the standard RS-232C interface. The buffered highspeed serial ports support transfer rates up to 115.2 KB. The ports allow the installation of highspeed serial devices for faster data transfer rates.

Sets of I/O addresses for the channels are given in the following table (see Section 2, “System

Configuration,” for interrupt levels). Soft-selectable base addresses are 3F8h, 2F8h, 3E8h, and

2E8h.

See Section 2, “System Configuration,” for information on resetting the port through the BIOS

Setup Utility. See Section 9, “Specifications,” for the serial interface specifications.

Serial interface signals are output through the system board’s 9-pin, D-subconnector. The connector is located at the back of the system unit.


USB Interface

The Universal Serial Bus (USB) ports allow plug and play serial devices to be added without having to open the system. One USB device can be plugged into each USB port for direct system connection. With a hub and the proper cabling, up to 127 USB devices per port can be addressed by the system.

The USB determines system resources for each peripheral and assigns them without user intervention. Boot support for a USB keyboard is present so the system can be booted with a

USB keyboard instead of a standard keyboard.

Accelerated Graphics Port

The system board contains an AGP connector for the system’s AGP video board. The AGP board has a graphics controller, video memory, and a VGA-compatible connector. The AGP port supports graphics-intensive, 2D/3D applications.

The 4X AGP graphics controller on the video board is specifically designed for graphicsintensive operations, including 3D and 2D effects, texture mapping, text and color pixel amplification, and video acceleration. The controller minimizes bus traffic by off-loading the tasks normally performed by the processor, providing 64-bit, high resolution performance for demanding True Color displays and other sophisticated graphics functions.

Connect a monitor to the AGP video board’s VGA connector on the back of the system.

Integrated Audio

To support multimedia applications, an Yamaha YMF 752-S audio chip is integrated on the system board. The chip provides 16-bit stereo, Sound Blaster Pro-compatible audio.

The sound system provides all the digital and analog mixing functions required for playing and recording audio on personal computers. Features include stereo analog-to-digital and digital-toanalog converters, analog mixing, anti-aliasing and reconstruction filters, line and microphone level inputs, digital audio compression, and full digital control of all mixer and volume control functions.

This section contains general information for cleaning and checking the system, keyboard, and monitor.

The system unit, keyboard, and monitor require cleaning and checking at least once a year, and more often if operating in a dusty environment. No other scheduled maintenance is required.

Unplug all power cords before performing any maintenance. Voltage is present inside the system and monitor even after the power is off. All voltage is removed only when the power cord is unplugged.

System Cleaning

Use the following procedure for cleaning the system.

1. Power off the system and unplug all power cables.

2. Wipe the outside of the system, keyboard, mouse, and monitor with a soft, clean cloth.

Remove stains with a mild detergent. Do not use solvents or strong, abrasive cleaners on any part of the system.

3. Clean the monitor screen with a commercial monitor screen cleaning kit. As an alternative, use a glass cleaner, then wipe with a clean lint-free cloth.

4. Local distributors and dealers may sell diskette drive head cleaning kits. These kits contain special diskettes and cleaning solution. Do not use the abrasive head cleaning kits (kits without cleaning solution).

Insert the diskette immediately after powering on the system, before disk bootup. Allow the diskette drive heads to clean for about 30 seconds.

Keyboard Cleaning

As necessary, inspect and clean the inside of the keyboard as follows.

1. Turn the keyboard over and remove the screws holding the keyboard enclosure together.

The keyboard and cable together are considered a whole-unit, fieldreplaceable assembly. Therefore, disassembly of the keyboard is necessary only when cleaning the inside.

2. Separate the two halves of the enclosure.

3. Clean the enclosure and keys with a damp cloth. Use a small, soft-bristle brush to clean between the keys.

Do not wet or dampen the keyboard’s printed circuit board. If the board gets wet, thoroughly dry it before reattaching the keyboard to the system unit.

6-2 Preventive Maintenance

Mouse Cleaning

The mouse has a self-cleaning mechanism that prevents a buildup of dust or lint around the mouse ball and tracking mechanism under normal conditions. Periodically, however, the mouse ball must be cleaned. Use the following procedure to clean the mouse.

Glossary

A

access time

The time period between the supply of an access signal and the output or acceptance of the data by the addressed system. Examples are the access times for DRAMs, SRAMs, hard drives, and CD-ROM drives. Hard drive access time is the time it takes for a computer to get data from the drive. A hard drive with an 11 ms access time is fast. A CD-ROM drive with a 280-ms access time is fast.

ACPI

Advanced Configuration and Power Interface. A power management specification developed by Intel, Microsoft, and Toshiba. When installed on the system, ACPI enables the operating system to control the amount of power given to each device attached to the computer. With ACPI, the operating system can turn off peripheral devices (such as CD-

ROM drives) when they are not in use. As another example, ACPI enables manufacturers to produce computers that automatically power up as soon as you touch the keyboard.

adapter

An expansion board or component on the system board that communicates with peripherals

(such as the display monitor or network devices).

address

A hexadecimal number that represents a location in storage or memory. Also used to identify communication ports. To communicate with a storage device.

AGP

Accelerated Graphics Port. A high-speed, high-performance video standard supported by a dedicated connector on the system board. The connector allows the connection of an AGP board to the system board’s AGP bus. AGP boards feature

64- or 128-bit graphics acceleration with an integrated digital video engine and accelerated

3-D graphics, texture mapping, and shading functions. Fast refresh rates, high resolution, and color depth allow for incredible graphics suitable for multimedia and graphic intensive applications.

algorithm

Any set of instructions to be followed in order.

anti-aliasing

Making jagged edges look smoother by filling in the jags with an intermediate color.

Usually used in reference to the edges of shapes, especially letters, on a computer screen.

API

Application Programming Interface. An API is a series of functions that programs can use to make the operating system do routine or repetitive tasks. Using Windows APIs, for example, a program can open windows, files, and message boxes (as well as perform more complicated tasks) by passing a single instruction. Windows has several classes of APIs that deal with telephony, messaging, and other issues.

Glossary 1

2 Glossary

APM

Advanced Power Management. An API developed by Intel and Microsoft that allows developers to include power management in the BIOS. APM defines a layer between the hardware and the operating system that effectively shields the programmer from hardware details.

application programs

Software designed to perform specific functions or a group of functions, like solving business or mathematical problems. Examples of applications include word processing, communications, or database management.

architecture

A general term for the design and construction of computer systems, particularly hardware, but also operating systems and networks. The circuitry within a chip is called its architecture; for example, Intel architecture can refer to a computer based on the Intel

Celeron, Pentium II, or Pentium III chips.

archive

Copying one or more files to a different location for long-term data storage, especially for backup and security purposes. Files can then be added to or deleted from the archive. Also refers to the location where data is stored.

ASIC

Application Specific Integrated Circuit. A chip designed for use on a particular circuit board, or for a very narrow range of use. The digital signal processor chip on a modem is an

ASIC.

asynchronous

Refers to operations that do not require the clocks of communicating devices to be coordinated. Instead, the devices send signals to each other indicating readiness to receive or send. Compare synchronous.

asynchronous cache

The slowest, most inexpensive type of secondary SRAM cache, running at speeds of 15 to

20 ns.

ATA

AT Attachment. A standard for connecting hard drives or other devices to an AT bus; synonymous with IDE.

AT bus

The AT bus system with support chips (DMA, PIC, etc) and a 16-bit bus slot. The AT bus is strictly defined by ISA.

audio

Relating to or capable of producing sound. Multimedia computers make extensive use of audio.

AVI

A digital movie format created by Microsoft. AVI is short for “audio/video interleave,” a method of including a digital movie and its accompanying sound in the same file. Files in the AVI format have the .AVI extension.

B bad sector

Part of a hard drive or diskette drive storage medium that doesn’t hold data. Formatting generally detects and marks these areas so they won’t be used. Certain utility programs do, too, and it is a good idea to run this type of utility occasionally to prevent data loss if the condition of the drive changes.

bandwidth

A measure of how much information something can carry. Specifically, data path times frequency. For example, the ISA bus has a data path of 16 bits (it can send 16 bits at a time) and typically operates at 8.33 MHz, so it has a bandwidth of

133.28 megabits per second (Mbps).

base RAM

Area of system memory between 0 and 640 kilobytes available to the user for operating system and application programs.

batch file

A file that contains a series of DOS commands. Batch files have the extension .bat. If you execute a batch file, DOS attempts to carry out all the commands in the file, in order.

baud

A unit of measure for modem speed. Literally, the number of voltage transitions per second.

Phone line limitations limit the actual baud rate of modems to 2400 baud, although the data transmission rate (bps) may be higher because of data compression.

BBS

Short for Bulletin Board Service. Software that serves as a communication and information source for computers that communicate by modem.

BIOS

Basic Input/Output System. A program or set of programs permanently stored in ROM chips installed on the system board. The BIOS contains functions that control the real-time clock, keyboard, disk drives, video display, and other peripheral devices. For example, the

BIOS Setup utility program is contained in the BIOS, and when you change the drive type, you change the BIOS.

bit

Binary digit. The smallest unit of computer data. A single digital piece of information, generally represented by the numeral 0 or 1. Usually the transition between the states of

+5V and -5V within a computer, the charge of a transistor in an integrated circuit, or the change in polarity of a magnetic region on a disk. See byte. Data compression schemes can enable the transmission of more than one bit per voltage transition.

bit block transfer

Moving part of a screen image as a single block rather than moving a pixel at a time. Bit block transfers are much faster than moving the same pixels individually, and it is common in accelerated video cards.

bitBLT

Bit Block Transfer.

Glossary 3

4 Glossary

bitmap

Any occurrence where a single location in memory and a single pixel correspond. Usually applies to screen or printer output. .BMP files are bitmapped graphics files.

bits per second

(bps) A unit of transmission. Also called baud rate.

block

A contiguous section of bits considered as a whole, especially in memory. On a disk, the data in one sector; in modem data transfer, the bits between checksums.

board

Printed circuit board. Board onto which computer components are soldered and thin wires are printed to connect the components.

boot

To start up a computer. The computer is generally booted in one of three ways: by turning on the power switch (cold boot), by pressing the reset switch, or by simultaneously pressing the Ctrl, Alt, and Del keys (warm boot). Booting the system after it has already been powered up and booted is referred to as rebooting. Also the process of booting itself. Boot is from “bootstrap,” a reference to a computer’s ability to set itself up, or pull itself up by its own ‘bootstraps.’ See cold boot and warm boot.

bootable device

Any type of hardware that carries the information (software) required by the computer to start properly. This device must also have the capacity to be recognized by the computer in the first stages of the boot process.

boot block

The part of a disk that contains the software (such as the operating system loader) that enables the computer to start.

boot sector

The part of the boot block that contains the operating system loader, a program that starts by itself and loads the operating system.

bps

Bits per second. The number of bits of data that can be transmitted in one second. Because data compression schemes enable more than one bit per voltage transition, bps is equivalent to baud only if no compression is used.

buffer

A place, especially in RAM, for the temporary storage of data for the purpose of speeding up an operation such as printing or drive access. Data from a buffer is available more quickly than data from where the buffer got it. Typically buffers get data before it is needed so it is ready quickly when needed. Similar to cache.

burst mode

When a device seizes control of the bus, sends data, then relinquishes control of the bus.

Any time a device sends data without interruption instead of taking turns with other devices.

bus

A parallel electrical pathway on the system board, connecting and shared by the parts of a computer system (especially the CPU, its support circuitry, memory, and expansion cards), used for transmitting data or electrical power from one device to another. Typically the lines in a bus are dedicated to specific functions, such as control lines, address lines, and data lines. Different bus architectures have different numbers and arrangements of these lines, and different names (for example, ISA, PCI). The most useful way of distinguishing bus architectures is by the number of simultaneous data bits they can carry. The ISA is a 16-bit bus, while PCI is a 32-bit bus.

bus master

The ability of an expansion card to control the bus without needing intervention from the

CPU.

byte

Group of eight contiguous bits. Frequently written as an eight-digit binary number or a twodigit hexadecimal number. One letter of the alphabet in ASCII code takes one byte.

C cache

A special block of fast memory used for temporary storage of frequently used data for quick retrieval. A memory cache, sometimes called a cache store or RAM cache, is a portion of memory made of high-speed static RAM (SRAM) instead of the slower and cheaper dynamic RAM (DRAM) used for system memory. Memory caching is effective because most programs access the same data or instructions over and over. By keeping as much of this information as possible in SRAM, the computer avoids accessing the slower DRAM.

See “write-back” and “write-through.” chassis

The metal frame to which the electronic components of the computer (such as the system board, power supply, and drive bays) are attached. The chassis goes inside the system unit cover.

checksum

A number, calculated from a block of data, used to verify the integrity of that data. For example, a modem could send a block of data and include the number of 1’s that occur in the block. The receiving modem could count the number of 1’s it receives and compare its own number with the transmitted number. If the numbers are the same, the transmission was probably OK.

clock

Electronic timer (oscillator) used to synchronize computer operations. The oscillator generates the timing pulses that coordinate and enable the flow of data within a digital device. Also a circuit powered by battery that keeps track of the date and time for human and various system requirements.

clock speed

The frequency at which a clock oscillates. In microcomputers, measured in MHz. The faster the clock, the faster the computer can compute.

hot plugging

The ability to add and remove devices to a computer while the computer is running and have the operating system automatically recognize the change. The Universal Serial Bus

(see USB ) external bus standard supports hot plugging. This is also a feature of PCMCIA.

Hot plugging is also called hot swapping.

I

IDE

Intelligent Drive Electronics. A hard drive type that has controller electronics built into the drive and delivers high throughput.

interface

A connection that enables two devices to communicate.

interrupt

A signal from part of a system, such as an I/O device, asking to use the CPU. Interrupts are hierarchical, which prevents interrupts from interrupting each other. (Whichever interrupt has higher priority makes the other interrupt wait.) When the CPU receives an interrupt signal, it saves what it is doing, processes the routine associated with the interrupt, then returns to what it was doing.

I/O address

Input-Output address. How the CPU sees an I/O port. It puts data into this address or reads the data in it. The device at the other end of the I/O port gets the data from that address or puts the data there, respectively.

IRQ

Interrupt Request. A signal that, when received by the CPU, makes it stop what it is going to do something else. An interrupt is a way in which a particular device in a computer communicates with the CPU. PCs have 16 IRQ lines that can be assigned to different devices (for example, printers, scanners, modems). No two devices can have the same IRQ address. See interrupt.

ISA

Industry Standard Architecture. The bus architecture used in the IBM PC/XT and PC/AT.

The AT version of the bus is called the AT bus and has become an industry standard. The apparent successor is the PCI local bus architecture found in most of today’s computers.

Most modern computers include both an AT bus for slower devices and a PCI local bus for devices that need better bus performance. In 1993, Intel and Microsoft introduced a new version of the ISA specification called Plug and Play ISA. Plug and Play ISA enables the operating system to configure expansion boards automatically so that users do not need to fiddle with DIP switches and jumpers. See plug and play.

PCI

Peripheral Component Interface/Interconnect. A self-configuring personal computer local bus designed by Intel. Most modern PCs include a PCI bus in addition to a more general

ISA expansion bus. PCI is a 32-bit bus, but supports a 64-bit extension for new processors, such as the Pentium II. It can run at clock speeds of 33 or 66 MHz. At 32 bits and 33 MHz, it yields a throughput rate of

133 megabits per second. 64-bit implementations running at 66 MHz provide

524 Mbps. See ISA.

R

RAM

Random Access Memory. A storage device into which data is entered and from which data is retrieved in a nonsequential manner. On the system board, RAM is semiconductor-based memory that can be read and written to by the microprocessor or other hardware devices. In

RAM, data can be directly and randomly read or written (with any choice for the address).

It’s the storage location for data that needs to be immediately available for every application in use on your computer.

RDRAM

Rambus Dynamic Random Access Memory: Memory used to store data in computers.

Rambus technology is incorporated onto dynamic-random-access-memory (DRAM) chips and the logic devices that control them. The Rambus DRAM delivers more than ten times the performance of conventional DRAMs. A single RDRAM transfers data at speeds up to

800 MHz over a narrow, Rambus Channel to Rambus compatible ICs. See DRAM.

read

RIMM

Rambus Inline Memory Module: Circuit board with pins connecting up to eight RDRAM memory chips on each side of the board, which allows for wider and faster data transfer.

See RDRAM and DIMMs.

ROM

S

SEC

Single-Edge Contact. The SEC cartridge containing the Pentium processor. See Slot 1.

serial interface

An interface that communicates information one bit at a time.

serial printer

A printer with a serial interface.

SGRAM

Synchronous Graphic Random Access Memory. A type of DRAM used increasingly on video adapters and graphics accelerators. Like SDRAM, SGRAM can synchronize itself with the CPU bus clock at speeds of up to 100 MHz. In addition, SGRAM uses several other techniques, such as masked writes and block writes, to increase bandwidth for graphics-intensive functions. Unlike VRAM and WRAM, SGRAM is single-ported (it can only be accessed by one device at a time). However, it can open two memory pages at once, which simulates the dual-port nature of other video RAM technologies (access by two different devices simultaneously). See VRAM and WRAM.

SIMM

Single Inline Memory Module. A small circuit board holding a group of memory chips.

Typically, SIMMs hold up to nine RAM chips. On PCs, the ninth chip is for parity error checking. Unlike memory chips, SIMMs are measured in bytes rather than bits. In today’s

SIMMs, each chip holds 2 MB, so a single SIMM holds 16 MB. SIMMs are easier to install than individual memory chips. The bus from a SIMM to the actual memory chips is 32 bits wide. A newer technology, called dual in-line memory module (DIMM), provides a 64-bit bus. To take advantage of the 64-bit bus on Pentium processors, use either DIMMs or pairs of SIMMs. See DIMMs.

Slot 1

The form factor for Intel Pentium processors. The Slot 1 package replaces the Socket 7 and

Socket 8 form factors used by previous Pentium processors. Slot 1 is a 242-pin daughter card slot that accepts a processor packaged as a Single Edge Contact (SEC) cartridge. A system board can have one or two Slot 1s. See SEC.

SMART

Self-Monitoring Analysis and Reporting Technology. A hard drive feature that works in conjunction with system software (for example, LANDesk Client Manager, NEC Auto

Backup) for identifying a potential problem on the hard drive and automatically backing up system files to a user-specified device, such as a tape or Zip drive.

U

Ultra DMA

A protocol developed by Quantum Corporation and Intel that supports burst mode data transfer rates of 33.3 MBps. This is twice as fast as the previous disk drive standard for PCs, and is necessary to take advantage of new, faster Ultra ATA disk drives. The official name for the protocol is Ultra DMA/33.

USB

Universal Serial Bus. An external bus standard that supports data transfer rates of 12 Mbps

(12 million bits per second). A single USB port can be used to connect up to 127 peripheral devices, such as mice, modems, and keyboards. USB also supports Plug-and-Play installation and hot plugging. It is expected to eventually replace serial and parallel ports.

V

VESA

Video Electronics Standards Association. The source of a SuperVGA standard used on many video boards.

virus

Software that copies itself onto hard drives and diskettes without user intervention, usually when a diskette is placed into the drive of a computer. Viruses usually trigger a harmless or destructive occurrence on the system, activated by some preset condition. Viruses are frequently written with antisocial intent.

VGA

Video Graphics Array. Graphics technology that supports up to 256 K colors and a graphics resolution of 640 by 480 pixels.

volatile memory

Storage media that loses its data when system power is turned off. Standard memory and memory added to the system are volatile memory. See nonvolatile memory.

VRAM

Video RAM. VRAM is special-purpose memory used by video adapters. Unlike conventional RAM, VRAM can be accessed by two different devices simultaneously. This enables a video adapter to access the VRAM for screen updates at the same time that the

CPU provides new data. VRAM yields better graphics performance but is more expensive than normal RAM. A special type of VRAM, called Windows RAM (WRAM), yields even better performance than conventional VRAM. See SGRAM and WRAM.

W warm boot

Process of resetting the computer without turning off the power through keyboard input

(pressing Ctrl , Alt , and Del keys simultaneously) or the reset button. The system returns to an initial or arbitrarily selected condition.

WRAM

Windows RAM. A type of RAM that supports two ports. This enables a video adapter to fetch the contents of memory for display at the same time that new bytes are being pumped into memory. This results in much faster display than is possible with conventional singleport RAM. WRAM is similar to VRAM, but achieves even faster performance at less cost because it supports addressing of large blocks (windows) of video memory. See VRAM and

SGRAM.

write

To record or store information to a storage device.

write-back

Also called copy back. A cache strategy where write operations to data stored in the internal microprocessor L1 cache aren’t copied to system memory until absolutely necessary. In contrast, a write-through cache performs all write operations in parallel; data is written to system memory and the L1 cache simultaneously. Write-back caching yields somewhat better performance than write-through caching because it reduces the number of write operations to main memory. See cache and write-through.

write-through

Also write-thru. Write-through characterizes a cache strategy where data is always written into system memory when data is written by the CPU. See cache and write back.
