Developed using the following state-of-the-art technology, these computers are the most value packed personal computers in their class.

Onboard Video

Plug and Play

Dual, Factory-Installed Operating Systems

Power Management

Acrobat

Network-Ready

Computer Security

Desktop Management Interface (DMI)


Onboard Video

Your computer offers onboard video with high-performance, Matrox Storm accelerated 2-D and 3-D graphics technology.  This technology takes full advantage of your Windows graphic applications, such as AutoCAD and video clips.  It allows for faster data transfers between supported CPUs and memory as well as high-speed screen refresh capabilities.  Major features include:

Graphical User Interface (GUI) Accelerator

PCI Local Bus Video Interface

Window RAM (WRAM) Frame Buffer

Monitor Timing Modes (Operating Frequency)

Display Power Management Signaling (DPMS) Support

Feature Connector


Graphical User Interface (GUI) Accelerator

This high-performance technology uses Window RAM (WRAM) memory to run graphic-intensive applications faster, speed up Windows, Lotus 1-2-3, AutoCAD, and more, eliminating the need for a separate “Windows accelerator” expansion card.  The GUI also provides 2-D and 3-D graphics acceleration for Windows AutoCAD.


PCI Local Bus Video Interface

This 32-bit PCI interface transfers information at up to 33 MHz, enabling your computer and monitor to communicate more efficiently.


Window RAM (WRAM) Frame Buffer

WRAM provides faster video than DRAM or VRAM and is state-of-the-art in video memory.  WRAM provides 20-ns access time, up to 400 MB/sec data bandwidth, video playback acceleration, upgrade memory to 8 MB with optional cards.


Monitor Timing Modes (Operating Frequency)

The onboard video circuitry supports monitors operating at high refresh rates that meet or exceed VESA standards.


Display Power Management Signaling (DPMS) Support

The onboard video circuitry is specifically designed to work with and support your computer’s energy-saving Advanced Power Management (APM) features.


Feature Connector

This standard 26-pin output-only VESA connector allows you to connect your computer’s onboard video circuitry to an additional expansion card (for example, an integrated multimedia card that manages video, sound, and CD-ROM information).


NOTE

Operation with a video card attached to the VGA feature connector is restricted to applications that do not write the palette.  For operation, you must enable the VGA feature connector at the BIOS Setup Menu.


Configuring Monitor, Windows for Workgroups

Your computer has various video applications. To configure your monitor to the resolution and color (pixel) depth you want for your Windows applications, do the following:

1.	From the MGA Millennium PowerDesk group in the Windows Program Manager, double click on the appropriate application icon, such as MGA Millennium Control Panel.

2.	Select the resolution and color depth you want then click on OK.
Your computer will then prompt you to restart Windows so you can use the new configuration.

Every application has a good help program that you can use as desired when using the application.


Configuring Monitor, Windows 95

Your Windows 95 computer has an application to change the color palette, font size, and the display resolution.  To access this application in Windows 95, do the following:

1.	Click on the desktop with the right (third) mouse button or use the Applications key on your keyboard.

2.	Select Properties from the popup menu.

3.	Choose the desired settings.

4.	Click on OK or Apply.

5.	Depending on the settings that you made, you may be prompted to restart windows for your changes to take effect.

Use the help feature with each application as desired.


Plug and Play

Plug and Play technology eliminates the process of manually configuring optional expansion boards for operation in your computer.  With Plug and Play, your computer’s BIOS and the hardware logic built into Plug and Play expansion boards work together to automatically assign the proper computer resources (interrupt requests (IRQs), I/O and memory addresses, and direct memory access (DMA) channels).

Plug and Play technology also makes installing older legacy expansion boards much easier.

Information about Plug and Play depends on what Windows-based operating environment you are using.

•	“Windows for Workgroups” - Refer to the on-line help in Plug and Play.  You can get this from the Program section of “Getting Started” or from the Digital group in the Windows Program Manager.

•	“Windows 95” - Plug and Play is integrated in Windows 95.  Refer to your Windows 95 information set.


Operating System
Dual, Factory-Installed Operating Systems

Most Celebris GL computers have dual, factory-installed operating system software; that is, MS-DOS and Windows for Workgroups, and Windows 95.  Users must choose one operating system or the other; they cannot run both.  When the choice is made, the other operating system is deleted from the hard disk.

Users who choose DOS and Windows for Workgroups, should use the utility inside “Getting Started” to make a copy of the selected operating system software.  The diskettes should then be put away in a safe place.  Should the hard disk fail or if the software is accidentally deleted, the diskettes can be used to reinstall the software.

Users who choose Windows 95 can reinstall the software using the CD-ROM discs and other necessary diskettes that are supplied with the computer.


CAUTION

If you are running or intend to run 32-bit applications, they probably will not run in the 16-bit, Windows for Workgroups environment.


Power Management

The Digital Power Management technology enables you to reduce your computer’s power consumption during system inactivity.  These options can be selected in Setup and include:

Power Management

System standby timeouts

System suspend timeouts

Quick Suspend

You can configure power management options in the BIOS Setup or by selecting Power Management in the Program section of “Getting Started.”  For information on the Windows-based Power Management program, refer to the on-line help with the Power Management program.


NOTE:

Your monitor and hard disk drive must be green ("Energy Star") compatible to use any of the monitor and disk drive power saving features contained in Power Management.

For more information on accessing and selecting these options, refer to the on-line Power Management and to the DOS/Windows documentation.


Power Management

To Enable:

Click your mouse on the check box next to the selection.  An X appearing in the box indicates that Power Management is enabled.  Clicking on the box again causes the X to disappear and disables the Power Management feature.

What It Does:

Enabling the Power Management selection activates the Advanced Power Management  (APM) functions of the POWER.EXE software driver.  Refer to MS-DOS and Windows documentation for additional information on POWER.EXE and APM.  This provides a base level of energy savings and allows you to use other power management features to increase the amount of energy saved.

NOTE
You must set Power Management to Enabled before selecting or using the other features available in the Power Management dialog box.


System Standby Timer

To Set:

Click your mouse on the timer setting you prefer.  The selected timer setting will be highlighted, and the other options dimmed.   To choose a different timer setting, click on that setting.

What It Does:

When the System Standby Timer is activated, and the computer has been inactive for the period of time you selected (for example, ten minutes), it enters a "standby" mode.  In the standby mode, the monitor and CPU operate at reduced power and a moderate level of energy savings is achieved.

You can quickly return your computer to full operation by pressing a key (for example, the Shift key), or moving the mouse.


System Suspend Timer

To Set:

Click your mouse on the timer setting you prefer.  The selected timer setting will be highlighted, and the other options dimmed.   To choose a different timer setting, click on that setting.

What It Does:

When the System Standby Timer is activated, and the computer has been inactive for the period of time you selected (for example, 1.5 hours), it enters a "suspend" mode.  In the suspend mode, the monitor is turned off, the hard disk drive spins down, and the CPU operates at minimum power.  These actions achieve a maximum level of energy savings.

You can return your computer to full operation by pressing a key (for example, the Shift key), or moving the mouse.  (It takes slightly longer for the computer to "wake up" from suspend mode than it does from standby mode.)


Quick Suspend

To Set:

Click your mouse on Quick Suspend to view a list of the available hot-key combinations.  Click on the combination you prefer to select it.

What It Does:

Enabling a Quick Suspend hot-key combination allows you to place your computer in suspend mode -- thus achieving maximum energy savings -- at any time by pressing the hot-key combination you selected from the list of those available.  (Refer to the System Suspend Timer pop-up for information on suspend mode.)

	CAUTION Application software sometimes uses hot-key combinations to perform specific tasks.  If Quick Suspend and a software application both attempt to use a specific hot-key combination for different purposes, unpredictable results may occur.


Acrobat

BIOS Utilities and Drivers
Updating the Computer’s BIOS

Celebris GL computers are equipped with flash memory.  This means that the computer's BIOS can be restored or upgraded simply by running the PHLASH.EXE utility.

There are several distribution channels for updated BIOS including the DECpc BBS.  To reach the DECpc BBS, from outside of Digital, call : 1-508-496-8800.

Select from the following topics for the processes to update the BIOS

Before Using PHLASH.EXE

Creating a Crisis Recovery Diskette

Using PHLASH.EXE to Update The Computer's BIOS

Using a Crisis Recovery Diskette


Multilingual BIOS Diskette (PHLASH .EXE)
Before Using PHLASH .EXE

Before you can upgrade the BIOS using PHLASH.EXE, you need to make a backup diskette (crisis recovery diskette) of the old BIOS.  It is important that you make this diskette.  Should you find the BIOS upgrade unsuccessful, you can use this crisis recovery diskette, to return to the old BIOS.  The following are needed to create this diskette:

•	A blank 3½-inch 1.44 MB formatted diskette

•	A diskette copy of the PHLASH Utility diskette


Creating a Crisis Recovery Diskette

Make sure you create a crisis recovery diskette before upgrading the BIOS.  If the upgrade is unsuccessful, you might find the computer no longer has a working BIOS.  Without a working BIOS you might not be able to operate your computer. With a crisis recovery diskette, you can always return to the previous level of BIOS.  To create this diskette

1.	Turn on the computer and allow the POST to complete.

If POST detects an error, refer to Troubleshooting  to identify and determine how to correct the problem.  After the problem has been resolved, restart the computer.

2.	Insert the PHLASH Utility diskette into the diskette drive and enter:

a:
dir/upgrade

The entry should show that the following files are on the diskette.

MINIDOS.SYS
PHLASH.EXE
MAKEBOOT.EXE
MAKECRD.EXE
DEVTBLS.DAT
PHLASH.INI
CELEBRIS.ROM

Note that there might be some additional files as well.  Refer to any appropriate README files for additional information:

3.	Create an upgrade directory on the hard disk drive.  For example, if the hard disk drive is c:>, enter at the DOS prompt:

c:
md upgrade

4.	Copy the files from the PHLASH Utility diskette into the upgrade directory on the hard disk drive.  For example, from the DOS prompt enter:

copy a:\upgrade\*.* c:\upgrade\*.*

5.	Insert a blank formatted diskette into drive A.

6.	On drive A, make a directory for the files previously copied.  For example, from the DOS prompt enter:

a:
md upgrade

7.	Return to the hard disk drive and copy the files.  From the DOS prompt that is:

c:
cd\upgrade
makecrd

The makecrd command prompts you for a recovery diskette to be placed in drive A and then automatically copies the files to drive A.

8.	Remove the crisis recovery diskette from drive A and store it in a safe place.


Upgrading Your Computer's BIOS
Using PHLASH.EXE to Update the Computer's BIOS

Perform the following steps to update the computer's BIOS in the flash memory to a new updated one.

1.	Locate or create a crisis recovery diskette.  (Do not use a crisis recovery diskette created on any other computer.)

Refer to Creating a Crisis Recovery Diskette.

2.	Insert the PHLASH Utility diskette with the new BIOS in the diskette drive.

3.	Turn on the computer and allow the POST to complete.

The computer now boots from the PHLASH Utility diskette.

If POST detects an error, refer to Troubleshooting  to identify and determine how to correct the problem.  After the problem has been resolved, restart the computer.

4.	At the MS-DOS prompt, type:

a:\upgrade\phlash

A screen appears on the monitor warning that the computer’s BIOS is about to be erased.

5.	Press [Enter] to continue.  Press [Esc] to cancel.

If [Enter] is pressed, PHLASH.EXE automatically updates the computer’s BIOS.

After the flashing process completes, the computer automatically reboots itself so changes immediately take effect.

6.	If a message appears indicating that the boot block is write-enabled, configure the boot block jumper. If not, go to step 7.

7.	Remove the PHLASH Utility diskette.


Configuring the Boot Block Jumper

Perform the following steps to configure the boot block jumper (J6).

1.	Turn off power to the computer.

2.	Disconnect external devices and power.

3.	Unlock and remove the cover.

4.	Change the jumper setting of J6 from position 1-2 to position 2-3.

5.	Replace and lock the cover.

6.	Reconnect external devices and restore power.

7.	Repeat steps 2- 5 of the BIOS update procedure.

8.	Repeat steps 2 and 3 of this procedure.

9.	Restore the jumper setting of J6 to position 1-2.

10.	Repeat steps 5 and 6 of this procedure.  The BIOS should now be successfully upgraded.


CAUTION

Read this procedure carefully and be sure you understand it before completing the steps listed in this procedure.


Using a Crisis Recovery Diskette

The crisis recovery diskette must be used only if the computer’s BIOS fails or if a BIOS upgrade was unsuccessful.  If the computer’s BIOS failed to flash properly or is corrupted in some way, the following sequence of events occurs:

•	POST detects an error after a normal boot cycle or a BIOS upgrade.
This message(s) appears on the monitor screen, indicating that the computer’s BIOS did not flash properly or has failed.

•	The BIOS in the bootblock memory automatically executes.
The computer attempts to find the correct BIOS files to execute the correct boot cycle.

•	The computer beeps several times.
This means the computer cannot properly boot using the BIOS files that were just copied during the flash update.

•	The computer accesses the diskette drive
The computer is searching for the crisis recovery diskette to restore the BIOS to its previous known state.

Restore the computer’s BIOS to its previous known state by performing the following procedures:

1.	Turn off your computer, unlock and remove the cover, and set the recovery jumper (J22) to “Recovery Mode” (jumper on).

Jumper J22 controls whether the computer is in recovery or normal operation.

2.	Replace the cover, insert the crisis recovery diskette into drive A, and then power on your computer.

Your computer automatically boots from drive A and upgrades the BIOS.  Upon completion, the computer sounds a beep code and attempts to restart.

3.	After the BIOS is restarted, turn off power to the computer and remove the crisis recovery diskette from drive A.

4.	Remove the cover and set the recovery jumper (J22) to “Normal” (jumper off).

5.	Replace and lock the left-side cover and turn the power back on for normal operation.

Expansion Slots

Click on the view button for a particular computer:

  Slimline Expansion Slots

  Short Tower Expansion Slots

Your computer automatically assigns the necessary resources to any installed Plug and Play-compatible expansion card so it operates at maximum performance.  If you plan on installing non-Plug and Play expansion cards, you might need to manually set jumpers on the board based on the computer resources already allocated.

Refer to the on-line help information in the ICU.  You can access the ICU through the “Getting Started” program.


NOTE:

When installing expansion cards, always read the accompanying documentation for computer memory address and IRQ requirements.  Compare that information to the computer memory and IRQ requirements in the appropriate CPU module specifications booklet.  If conflicts are detected, you must configure the expansion card to alternate settings.

•	The top device bay (for Slimline computers) or the bottom three device bays (for Short Tower computers) can be accessed from the front of the computer and can hold 3½-inch or 5¼-inch half-height devices.  Examples include diskette drives, tape backup drives, CD-ROM drives, or hard disk drives.

•	The next-lower device bay (Slimline) contains a factory installed 3½-inch diskette drive.

•	The top device bay (Short Tower) contains a factory installed 3½-inch diskette drive.

•	The bottom-front and rear device bays are not accessible from the front of the computer and only support 3½-inch hard disk drives.


NOTE:

Refer to the manufacturer's instructions for your mass storage device to determine if switches, jumper settings, or terminating resistors need to be set or installed on the device.  Set all applicable switches and jumpers, or remove terminating resistors prior to installing any mass storage device.

Installing Video Memory


Installing Additional Computer Memory

Adding more memory allows the computer to run larger, more complicated software and run it more quickly.

Depending on the model you purchased, your computer comes with either 8 MB or 16 MB of onboard memory.  For those with 8 MB computers, memory is installed as two 4 MB SIMMs in bank 1 (socket 0 and 1).  For those with 16 MB computers, memory is installed as two 8 MB SIMMs in bank 1 (socket 0 and 1).  You can increase this amount up to a maximum of 128 MB using the four SIMM sockets on the main logic board.

Note that Extended Data Out (EDO) memory is available in 8 MB and 16 MB SIMMs and Error Correction Code (ECC) memory is available in 16 MB SIMMs only.  EDO memory is faster than standard non-parity memory while ECC memory is for mission critical reliability.

To learn more about adding computer memory click on the following:

Guidelines for Adding SIMMs

Installing SIMMs

Memory Configurations


{bmc DEC565_3.WMF}


Guidelines for Adding SIMMs

When adding SIMMs make sure you:

•	Install 32-bit SIMMs having an access time of 70 ns or less.  Supported SIMM sizes:  4 MB, 8 MB, 16 MB or 32 MB (60 ns for EDO DRAM).

•	For improved performance, Celebris GL and GL [image] computers are designed with paged mode memory.  This feature requires that you populate both sockets in each bank  You must ensure that the SIMM in each socket is the same type, size, and speed.  Therefore, a 4 MB SIMM in SIMM socket 0 requires a 4 MB SIMM in SIMM socket 1.

•	You can mix memory types.  If you choose to do so, you can maximize performance by placing the EDO memory in the first bank.


CAUTION:

You cannot mix memory types in the same bank.


Installing SIMMs

To install a SIMM, perform the following:

1.	Turn off the computer.

address

A specific location or range of locations in your computer's memory or in a port (such as a parallel or serial port).  Memory addresses specify the location of information, while I/O addresses specify the location of a port used by a particular component of your computer.


application

A program or set of programs that operate in conjunction with an operating system, also called “application software”.  Categories of application software include word processors, databases, spreadsheets, and telecommunications software.  Specific examples of application software include WordPerfect, Lotus 1-2-3, and Procomm Plus.


AUTOEXEC.BAT

A special-purpose batch file.  Each time you turn on or reboot your computer, MS-DOS searches for the AUTOEXEC.BAT file and executes the commands in that file.  (If MS-DOS cannot find an AUTOEXEC.BAT file, the computer might not boot properly or operate correctly.)


base memory

Memory accessible to MS-DOS, up to a maximum of 640 KB; also called “conventional memory”.  See also expanded memory (EMS) and extended memory (XMS).


Basic Input/Output System

Abbreviated as BIOS.  The BIOS enables your computer to control major input/output devices such as the keyboard and disk drives.


batch file

A defined series of commands saved in a file, which can then be executed as a unit in order to save time and/or keystrokes.  (MS-DOS batch files have the extension .BAT.  Batch files created for other operating systems, such as Windows, might have other extensions.)


board

A device containing electronic circuitry and microprocessors.  Usually used in connection with a modifying word, as follows:
main logic board	The primary electronic component of your computer.
expansion board	A board which enhances your computer’s abilities in some way
video board	A board which enables your computer to display information on a monitor


booting

The process of self-testing and computer configuration that completes each time your computer is turned on (a “hard boot”) or restarted (a “soft boot” or “reboot”) by pressing the reset button or the [Ctrl]-[Alt]-[Del] key combination.  This might include a memory test, loading of device drivers via CONFIG.SYS, and execution of the AUTOEXEC.BAT file.


bit

The smallest unit of electronically stored information, represented by the binary digits 0 or 1.  (See also byte.)


bits per second

Abbreviated as bps.  The number of binary digits transmitted by an electronic device (such as a modem) in one second.  Also see bit.


byte

The amount of storage space used to represent one character (such as a letter or number).  One byte contains eight bits.  The following table describes other commonly-used units of electronic storage space.  These units are typically used to describe amounts of available memory.

Kb	Kilobit	1,024 bits
KB	Kilobyte	1,024 bytes
Mb	Megabit	1,048,576 bits
MB	Megabyte	1,048,576 bytes
GB	Gigabyte	1,073,741,824 bytes


cache memory

A block of reserved memory that improves computer performance by minimizing the number of CPU memory accesses.  The computer achieves this by storing recently used data or instructions in reserved memory, where it can be retrieved more quickly.


CD-ROM

Compact Disk-Read Only Memory.  The CD-ROM drive and CD-ROM disk comprise an integral part of a multimedia computer system.  The disk stores a very large amount of audio, video, graphic and/or encyclopedic information that is read by the drive for use in a computer application.  Because the disk is read only, you cannot write to the disk from your computer’s hard drive, floppy drive, or from your computer’s memory.


central processing unit

Abbreviated as CPU.  A computer chip; specifically, the microprocessor that forms the heart of your computer.  Examples include Intel’s i486 and Pentium CPUs.


CMOS

A type of memory that uses very little power.  CMOS memory is often used to store information such as the time and date for your computer’s internal clock.


command line

The basic prompt presented by an operating system such as MS-DOS (for example, C:\>), from which you can execute operating system commands or run application software.  An alternative to a graphical user interface.


CONFIG.SYS

MS-DOS uses the CONFIG.SYS file to help configure your computer to correctly operate the specific hardware and software installed in your system.  Each time you turn on or reboot your computer, MS-DOS uses the CONFIG.SYS file to identify and load device drivers needed to operate specific hardware and software.


cursor

A line, block, or other indicator on your monitor screen.  The cursor identifies the point at which typed characters or other information will appear on the screen.  (Note that while a mouse or other pointing device can often be used to move the cursor, the mouse-pointer and a normal cursor might appear in different places on your screen.)


device driver

A file that gives your computer specific information on operating a particular physical device (such as a CD-ROM drive or a mouse) or application software (such as a memory manager).  Device drivers are usually loaded into memory each time your computer boots if they are listed in your CONFIG.SYS file.)


Direct Memory Access

Abbreviated as DMA.  The ability to display or deliver information from your computer's memory without making use of the microprocessor.  Devices with DMA capability (for example, many sound cards) must be properly configured in order for your computer to recognize and make use of this ability.


DPMS

1.	Display Power Management Signaling.  Technology that allows video controller circuitry to control the operating condition of a monitor, thereby decreasing the monitor’s energy consumption.

2.	DOS Protected Mode Services.  A way for software application to access extended memory, often by use of a specialized device driver.  Examples of software that uses DPMS include certain versions of Stacker and PKZip.


ECC

Error Correction Code, main memory system that detects and corrects memory bit errors; eliminates need for memory parity bits.  This memory is for systems that need mission-critical reliability and is only available in 16-MB SIMMs.


Enhanced Parallel Port (EPP)

An option available in your computer's BIOS which affects the way a printer attached to your parallel port communicates with your computer.  If your printer supports this standard, enabling the EPP option will allow faster printing.


expanded memory (EMS)

Memory beyond 640 KB that can only be accessed by use of expanded memory manager software.  Expanded memory can be provided by installing an expanded memory expansion board, or by using software that enables extended memory to simulate expanded memory.  Some application software requires expanded memory in order to operate correctly.


Extended Capabilities Port (ECP)

An option available in your computer's BIOS which affects the way a printer attached to your parallel port communicates with your computer.  If your printer supports this standard, enabling the ECP option will allow faster printing.


EDO

Extended Data Out, a DRAM feature that allows fast, main memory access timing.  EDO memory is faster than standard memory and is available in 8-MB and 16-MB SIMMs.  However, EDO memory should not be mixed with standard memory.


extended memory (XMS)

Memory beyond 1 MB that can only be accessed by use of extended memory manager software (such as HIMEM.SYS, included with MS-DOS).  Some application software, including Windows and Windows-based software, requires extended memory in order to operate correctly.  Extended memory can be added to your computer, within specified limits, by installing SIMMs.


firmware

Information that is permanently stored in your computer’s ROM and cannot be changed.  This might consist of application software and/or configuration information about certain aspects of the computer.  Your computer’s BIOS (see Basic Input/Output System) is an example of firmware.


graphical user interface

Abbreviated as GUI.  The visual “desktop” image generated by software such as Windows, that allows you to operate your computer by using a mouse or other pointing device to manipulate icons that might represent application software, files containing data, and/or operating system commands.  An alternative to a command line.


hardware

Computers, printers, modems and other physical devices for managing electronically stored information.


icon

A symbol or picture on your monitor screen that represents a file, a software application, an operating system command, or some other form of stored information.  Groups of icons might sometimes be referred to as button bars or toolbars.


interrupt

An event, condition, or instruction which causes your computer to temporarily stop performing a task, but does so in a way that permits the task to be resumed and completed later.  For example, not using your keyboard or mouse for several minutes might cause a screen saver program to interrupt another software application.  (Interrupts also occur within your computer's memory that cannot be easily detected by users.)


IRQ

A hardware setting which instructs your computer how to allocate memory resources between various components of the system.  For example, serial ports COM1 and COM3 are often assigned to the same IRQ setting.  If IRQ settings are not properly allocated to the various components of your computer (such as expansion boards), your computer might not be able to operate all of the affected components.

An IRQ setting on a given component establishes an interrupt condition for that component.


legacy

A legacy expansion board is any ISA board that does not comply with the new Plug and Play ISA Board Specification.  Legacy ISA boards must be configured using the ISA Configuration Utility (ICU).


mapping

The process of identifying specific addresses and locations within your computer’s memory, and describing what kinds of information might be found at those locations.  Sometimes referred to as device mapping or memory mapping.


media

Physical objects or devices used for storing information.  These might include floppy disks, hard disk drives, CD-ROM disks, and PCMCIA cards.


memory

The electronic space in which information can be stored and/or processed.  Types of memory include Random Access Memory (RAM), Read-Only Memory (ROM), expanded memory (EMS) and extended memory (XMS).


memory-resident

A condition in which software remains loaded in your computer's memory but does not operate until and unless it is activated by the user or by another software application.  For example, a virus-detection program might be memory-resident.


microprocessor

A computer chip that processes electronic information and instructions, such as Intel’s i486 or Pentium computer chips.  (Note, however, that not all microprocessors are central processing units.)


modem

A device for transmitting electronic information from one computer to another at high speeds over telephone lines.


multimedia

A form of electronic information that combines pictures, sounds, and text in an integrated manner. CD-ROM hardware and software is usually required to make use of information stored in the form of multimedia.


onboard video

Video controller circuitry that is incorporated into a computer’s main logic board, so that you do not need a separate video adapter to display information on a monitor.


operating system

The software that tells your computer how to manage and process electronically stored information, enables it to run application software, and controls the flow of information between various parts of your computer system.  MS-DOS, OS/2, and UNIX are operating systems.


port

The physical connection between your computer and a peripheral device, such as a printer, mouse, or SCSI device.

Parallel ports, also called LPT: ports, are typically used to connect your computer to a printer.  Serial ports, also called COM ports, can be used to connect your computer to a variety of devices, including a mouse, a modem, and some printers.  Other types of ports can include keyboard ports, mouse ports, and SCSI ports.


Power-On Self Test

Abbreviated as POST.  A series of diagnostic tests performed by your computer every time it is turned on (but not necessarily every time it is booted).


Random Access Memory (RAM)

Abbreviated as RAM; also called read/write memory.  The memory your computer uses to manage information and software while that information and software is in use.  Information stored only in RAM is lost when your computer is turned off.


Read-Only Memory (ROM)

Abbreviated as ROM.  Information or software stored in ROM is permanent, cannot be altered, and remains intact when your computer is turned off.  (Note that you cannot move or copy information into ROM from other areas of your computer’s memory.  In some cases, however, you can copy information from ROM into other areas of your computer’s memory.)


ROM BIOS

See Basic Input/Output System and Read-Only Memory.  ROM BIOS software enables your computer to control major input/output devices such as the keyboard and disk drives.


SCSI device

Hardware that communicates with your computer via a specific data-transmission technology (Small Computer System Interface).  Devices that use the SCSI interface include CD-ROM drives and some hard disk drives.


SIMM

A Single In-line Memory Module. SIMMs are small memory boards that can be used to increase the amount of random access memory (RAM) in your computer.


software

A program or set of programs that operate in conjunction with an operating system, also called “application software”.  Categories of application software include word processors, databases, spreadsheets, and telecommunications software.  Specific examples of application software include WordPerfect, Lotus 1-2-3, and Procomm Plus.


system utilities

Software designed to increase your computer’s efficiency, determine whether it is operating properly, and/or correct problems that might arise as you use your computer.  Some system utility software might be provided with your computer (such as a Setup program).  Other utility software is available from various commercial and non-commercial sources.  Examples of utility software include Stacker, PKZip, and PC Tools.


upper memory

The area of memory between base memory (640 KB) and 1 MB.  When properly configured, MS-DOS can load itself, device drivers, and memory-resident software into upper memory.  While the upper memory area can be configured as expanded memory, expanded memory is not limited to the upper memory area.


video adapter

Also called a video controller or video board.  A board that enables your computer to display information on a monitor screen.


video controller

The electronic circuitry which enables your computer to display information on a monitor screen.  This might be provided on a video adapter or on the main logic board.  In the latter case, it is referred to as onboard video.

Introduction

Using the DMI


Introduction

The Desktop Management Interface (DMI) is specialized record-keeping software that you can use to keep track of your computer's installed hardware and software.  This information is stored in a Management Information Format or MIF file database.

The DMI comprises the following:

•	Service Layer - a local program that collects information from products and manages that information in the MIF database.

•	MIF Database - contains the information about the products on the system.

•	Management Interface - allows a management application to query for lists of manageable products.

•	Component Interface - handles communication between manageable products and the Service Layer.

MIF file


Service Layer

The Service Layer is a local program that collects information from products, manages that information in the MIF database, and passes the information to management applications as requested.  It controls communication between itself and management applications via the Management Interface (MI) and between itself and manageable products via the Component Interface (CI).  The Service Layer is started when you enter the Windows environment and continues to monitor your system in the background until you close (exit) Windows.


MIF Database

The MIF Database contains the information about the products on the system.  The information comes from MIF files provided with each manageable product.


Management Interface

The Management Interface allows a management application to query for lists of manageable products, access specific components, and get and set individual attributes.  The MI also allows a management application to tell the Service Layer to send information about indications from manageable products.


Component Interface

The Component Interface handles communication between manageable products and the Service Layer.  The CI communicates with manageable products for get and set operations, receives indications from manageable products, and passes those to the MI.


Management Applications

Management applications are remote or local programs for changing, interrogating, controlling, tracking, and listing the elements of a desktop computer system.  A management application can be a local diagnostics or installation program, or an agent that redirects information from the DMI over a network.


Manageable Products

Manageable products are hardware, software, or peripherals that occupy or are attached to a desktop computer or network server.  These include hard disks, word processors, CD-ROMs, printers, main logic (mother) boards, operating systems, spreadsheets, graphics cards, sound cards, and modems.  Each product provides information to the MIF database by means of a MIF file that contains the pertinent management information for that product.  Once installed, these manageable products communicate with the Service Layer through the CI.


MIF File

A product’s manageable attributes are described in a language called the Management Information Format, or MIF.  The MIF has a defined grammar and syntax.  The MIF file is a simple ASCII text file describing a products manageable attributes, grouped in ways that make sense.  Each product has its own MIF file.  When a manageable product is installed, the information in its MIF file is added to the MIF database.  This information is then available to the Service Layer and thus, to the management applications.


Using the DMI

At present, you must enter information into the MIF file manually, using the DMI Database Editor (MIFWorks).  If you install or remove hardware or software from your computer, you should edit the MIF file to reflect the changes to your computer's configuration.  To do this, perform the following steps:

1.	Double click on the "Digital MIFWorks" icon, found in the Digital program group in Windows.

2.	Examine the data displayed in the MIF editor.  Using the mouse and keyboard, highlight the Component (such as MIF or DMI Service Layer) the desired MIF file group is in.

3.	Highlight the Group that the MIF file is in.

4.	Highlight the MIF file you want to change.

5.	Change any incorrect information and/or add new information as appropriate.

6.	When you are finished updating the MIF information, click the OK button to save your changes.

7.	Exit from the MIF editor.

MIF Database Editor

The MIF database editor (MIFWorks) consists of an application window and five secondary windows.  These windows are:

•	Components - Lists the DMI components, such as Digital Equipment Corp. PC System MIF and DMI Service Layer.  This window is displayed at the top, left-hand side of the application window.

•	Groups - Lists the MIF groups, such as BIOS Characteristics, ComponentID, Keyboard, General Information, and Service Layer Characteristics, within each of the Components.  This window displays at the middle, left-hand side of the application window.

•	Attributes - Lists single characteristics of a manageable product, such as Installation Date and Time of the system, actual system date and time, and DMI Directory.  This window displays at the bottom, left-hand side of the application window, depending on what group is highlighted.

•	Info/Description - This larger window displays at the right-hand side of the application window.  The window title changes to the current window that your cursor is in; e.g., if your cursor is in the Group window, the info window title will be Group.  This window also allows you to change the value of certain attribute window attributes, such as date and time, when they are highlighted.

•	Group Field Editor - This is a full-width popup window that allows you to change values in specific fields of multiple group attributes.


Components Window

Use the Components window to highlight the system component that you want to view for information or for selection of specific groups in the Group window.  Use your keyboard tab and cursor keys or mouse to highlight your selection.  Once you have made your selection, the Group window will display all of the group elements within the selected Component.  The Info/Description window will be titled Components.


Groups Window

Use your mouse or keyboard to select the component Group that you want to view or modify.  Depending on the group, either the Attributes window or the Group Field Editor window will display the attributes that you want to view or modify.  If you select groups such as ComponentsID or General Information, the Attributes window will display the attributes.  Other selections will be displayed in the Group Field Editor window.  The Info/Description window will be titled Groups.


Attributes Window

The Attributes window displays the attributes of certain groups such as ComponentID and General Information.  Use your mouse or keyboard to select the attribute you want to view or modify.  To modify the selected attribute, you will use the Info/Description window.  The Info/Description window will be titled Attributes.


Info/Description Window

The Info/Description window displays pertinent information about Components, Groups, and Attributes of your computer system.  If you select an attribute in the Attribute window, this window becomes an edit window.  To edit an attribute:

1.	Using your mouse or keyboard, select the attribute in the Attribute window.  The window changes from an information window to an edit window.

2.	Click your mouse on the Change Value button or press the Enter key.  An editing window will display the fields of the selected attribute.

3.	Use your mouse or keyboard to highlight the field you want to modify and make the desired changes.

4.	Use the OK button to save your changes, or the Cancel button to discard the changes and return to the previous value(s).  You will return to the Info/Description window.

5.	You may now select another attribute or return to the Groups or Components window.


NOTE:

Certain group attributes cannot be user-edited or modified, even though the Info/Description window becomes an edit window.  For example: attributes of the Service Layer Characteristics.


Group Field Editor Window

To use this window to view or modify the attributes of groups selected in the Groups window:

1.	Use your mouse or keyboard and select the group with the attributes you want to view or modify.  The Editor window will display the attributes of the group and the editable fields.

2.	Using your mouse, select the field you want to modify and click the Change Value button.

3.	Make your changes in the field window that pops up and click on OK to save your changes or Cancel to discard your changes.  You will return to the previous field select window where you can select another attribute field.

4.	Click the OK button to return to the MIFWorks windows.  You may now make another selection.

5.	When you are all done, click on File and then Exit to return to Windows Program Manager.
