Chapter 1, General Information
In the rapidly changing world of computer technology, every computer owner wonders if their system could one day become obsolete. ALR has conquered the fear of obsolescence with the introduction of the PowerFlex, a 286-based system enhanced with ALR’s unique 108-pin 386/1486 Feature Connector. This unique feature currently allows you to upgrade the standard
12.5-MHz 286 PowerFlex system to a 16-MHz 386SX or 25-MHz 1486 system by plugging in either a PowerFlex 16-MHz 386SX or 25-MHz i486 Module. That’s all there is to it. There are no switches to change on the 286 motherboard. When you plug a PowerFlex Module in, it simply takes over and you instantaneously attain the higher technological level that you were seeking.
Furthermore, ALR has no intention of limiting the PowerFlex to the 386SX and i486 modules. Future PowerFlex modules with even higher levels of technology are already being developed. When you’re ready to move up from 286 technology, simply contact your authorized ALR dealer to learn what PowerFlex modules are being offered, and to decide which upgrade module would best suit your needs.

PowerFlex system

The PowerFlex is a flexible IBM AT-compatible computer. The motherboard provides embedded I/O ports, floppy and hard disk controllers leaving all six IBM PC/AT expansion slots available for individual requirements. The PowerFlex also features a unique hardware and software Expanded Memory Specification (EMS) device driver that allows the user to run extended features of many popular software applications such as Lotus 1-2-3, Ventura Desktop Publishing, and Microsoft Windows. Add to this ALR’s unique 386/i486 Feature Connector, and you have a system that is almost boundless in its expansion capabilities, making the PowerFlex the ideal entry-level computer.
The standard PowerFlex is a 12.5-MHz 286 CPU system with a 3½-inch 1.44-MB floppy disk drive using the motherboard’s embedded floppy controller. The embedded 40-MB < 40ms AT-style hard disk drive provides full-track buffering and 1:1 page interleave.
The chassis is ALR’s specially designed small footprint AT-style desktop with a total dimension of 6" H x 15" W x 17" D which can accommodate two half-height 5¼-inch and two 3½-inch devices.

Components and performance features

Figure 1-1 shows the major components inside the PowerFlex. The following subsections describe these major components.
Memory
The PowerFlex is based on a 12.5-MHz 286 motherboard. The standard PowerFlex contains 1-MB of paged mode memory that occupies Banks 1 and 2. Banks 3 and 4 each contain two rows of Single Inline Memory Module (SIMM) connectors for mounting additional 256K x 9 or 1MB x 9 SIMMs. The maximum onboard memory is 5-MB. System memory may be expanded to 16-MB with the use of third party 16-bit memory expansion cards. See Chapter 4 of this manual for complete memory configuration and installation details.
PowerFLEX Users Manual 1-2

General Information Components and performance features
Drives and controllers
The PowerFlex chassis accommodates two 3½-inch and two 5¼-inch devices. The floppy disk drive included with the PowerFlex is a 1.44-MB 3½-inch floppy drive. The drive is springloaded and ejects diskettes about an inch. The floppy controller, integrated on the 286 motherboard, supports up to two 3½-inch drives with 720-KB or 1.44-MB capacities or, up to two 5¼-inch drives with 360-KB or 1.2-MB capacities.
The standard PowerFlex includes a 3½-inch 40-MB (<40ms) embedded hard disk drive. This drive is a special AT-interface drive that contains controller functions; hence, the name embedded hard disk drive. In addition, the controller functions can accommodate up to two hard disk drives allowing for storage expansion.
The PowerFlex chassis can accommodate two other half-height devices. You can use these storage bays to install optional floppy drives (any combination of 3½ and 5¼-inch drives are possible), hard disk drives, or tape backup systems. See Chapter 5 for further details.
BIOS EPROM
The Basic Input/Output System (BIOS) from Phoenix Technologies Ltd. controls the input/output (110) devices in the system. The I/O protocol for peripheral devices such as terminals, printers, and scanners is completely IBM-compatible.
There are no switches to set on the PowerFlex as all configuration changes are made through the PowerFlex SETUP program. A special SETUP screen, dedicated solely to select Soft Switch options, is one of three SETUP screens specially designed for the PowerFlex (see Chapter 2). An additional feature of the BIOS allows you to activate the SETUP program by pressing simultaneously the CTRL-ALT-ESC keys at the DOS prompt, or if the system’s setup configuration is incorrect, the system prompts you to press the F2 key.
Keyboard features
The PowerFlex includes an enhanced IBM AT-compatible keyboard with the added feature of audible keystrokes. Plus, you can change the operating speed by simply pressing the CTRL-ALT-MINUS or CTRL-ALT-PLUS sequences (see Chapter 2).

Standard software

The utility programs in the utilities diskette include hard disk formatting programs, drivers for two versions of Novell’s NetWare, and the Expanded Memory Specification (EMS) device driver. The diskette provides separate subdirectories containing each set of utility programs. Each subdirectory includes a README file explaining the functions of the associated utility. Chapter 3 describes how to use the utilities diskette.
ALR does not provide standard DOS with the PowerFlex. However, the PowerFlex is compatible
PowerFLEX Users Manual 1-3

General Information Components and performance features
with MS-DOS 3.3x and IBM PC-DOS version 3.3. ALR provides MS-DOS version 4.01 as an option. Note: The BASIC and BASICA software from IBM PC-DOS will not run because they require BASIC support in the BIOS and therefore will run only on IBM systems. We do include GW-BASIC in our MS-DOS option; this will provide the same function as BASICA (GW-BASIC is written by Microsoft).

Chapter 2, Getting Started

Charging the system battery

This system is equipped with a Nicad rechargeable battery with a built-in trickle-charge circuit. A completely charged battery will maintain its charge for two months. Upon delivery this system battery requires an initial charging period of approximately 12 hours. Prior to complete charging, the system may power up with an error in the setup configuration. Should this occur, simply press the F2 key to run the SETUP program. Refer to the section entitled, “SETUP program,” later in this chapter for further information on the SETUP program.
To charge the Nicad battery, simply plug your PowerFlex into a 3-prong, 115-volt AC surge control outlet station and turn the system ON. Leave the system running for at least 12 hours to fully charge the battery.
After charging, the Nicad battery should provide approximately a two-month backup charge without a recharge (recharging is done by running the system). The total lifetime of the battery is approximately 10 years.

Hooking up the monitor and keyboard

The monitor and keyboard are completely assembled at the factory; however, you must connect cables between the system, the monitor, and the keyboard. Figure 2-1 shows the rear of the PowerFlex chassis. This figure shows input/output (I/O) connectors for the keyboard, monitor (A.C. OUT), and optional equipment (COM1, LPT1 and Expansion Slots).
Connect your monitor and keyboard securely into the proper connectors. Most monochrome monitors have a separate ON/OFF switch and a power connector that plugs into the rear of the chassis. Refer to the appropriate manual that came with your monitor for further details.

Power-up operation

Turn the power ON. The ON/OFF switch is at the front of the chassis as shown in Figure 1-2. Turn the monitor power ON. The power LED lights if power is on.
On power-up, the PowerFlex checks its system memory. This occurs whether or not the monitor is also on. The system memory check (called the Power-On Self-Test or POST) takes from 3 to 15 seconds to complete, depending on system memory capacity. It ends with a single beep and a display of the time and date. The monitor displays the power-on message, as shown in Figure 2-2.

WARNING: You must allow the PowerFlex POST sequence to be completed before you turn the PowerFlex off. If you turn your system off immediately after a power-up sequence, wait until your DOS or OS/2 prompt appears on the screen. Failure to do this may cause errors in the SETUP configuration requiring you to re-run the SETUP program.

Getting Started Power-up operation
If the system fails the memory test, the monitor displays an error message preceded by two beeps. If the video adapter is not initialized when the error occurs, a beep code signals the error message. Appendix A lists the power-on self-test (POST) error messages. Most messages are nonfatal or offboard failures. If a fatal error message occurs, contact ALR for field service support. Do not return any equipment to the factory without obtaining a Return Material Authorization (RMA) number.
Insert your DOS diskette in Drive A. Press Fl to reboot the system, as follows:
F1
The system responds with the following:
Current date is Wed 06-14-1989 Enter new date (mm-dd-yy): <¿> Current time is 14:10:45.05 Enter new time: <¿>
Run the SETUP program by pressing the F2 key if the date or time is incorrect or if the system powers up with the message INVALID CONFIGURATION INFORMATION. The section entitled SETUP program later in this chapter explains how to use the SETUP program.

Initializing the hard disk drive

You must initialize (partition and format) the hard disk drive before you can run any software. To initialize the hard disk (to prepare it for DOS), use the FDISK and FORMAT commands.
NOTE: To eliminate major problems during partitioning (FDISK) or formatting (FORMAT), make sure the system is running in LOW speed during these operations. Refer to the next section of this chapter for information on selecting an operating speed.
Use the following procedures to partition and format the hard disk:
1. Partition the hard disk drive using FDISK.
Insert your DOS diskette in Drive A and boot the system by entering:
F1 (F1 = function key)
Partition the drive by entering:
A> FDISK <Enter> The FDISK program displays a series of menus to help you partition your hard disk for
MS-DOS. The system reboots after it completes the FDISK program. If the system does not allow you to complete the FDISK procedure, make sure the system setup information is correct. More specifically, you need to make sure the drive type is correct. A label indicating the
PowerFLEX Users Manual 2-3

Getting Started Initializing the hard disk drive
appropriate drive type is attached to the ALR hard drives. The PowerFlex SETUP program is described later in this chapter in the section entitled SETUP Program.
NOTE: The hard disk drive is low-level formatted at the factory —you should use the low­level format procedure only if your hard disk drive has crashed. (If your hard disk drive has
crashed, you normally receive the error message, “Hard Disk Failure.”)
2. Initialize the hard drive.
With the DOS diskette still inserted in Drive A, format the hard disk by entering:
A>FORMAT C:\S <Enter>
You can now boot the hard disk drive. To verify that it is bootable, open the door to Drive A and reboot the system by entering:
CTRL-ALT-DEL (DEL = DELETE key)
The DOS system prompt is displayed from Drive C as
C>
Your PowerFlex hard disk system is now ready to run DOS.

Selecting an operating speed

The system CPU clock is 12.5-MHz for the standard PowerFlex. On some occasions, you may wish to change the operating speed (for example, some software applications, such as Lotus 1-2-3, require a slower speed at installation). You can change to a slower or higher speed via a keyboard command sequence.
A keyboard command sequence changes the speed during normal computer operation. The command sequence changes the speed between low and high speed each time you enter the following commands:
C> CTRL-ALT-PLUS (the numeric keypad + key) C> CTRL-ALT-MINUS (the numeric keypad - key)
The preceding commands change the operating speed to low speed after the MINUS sequence and to high speed after a PLUS sequence. A beep following these commands signals the speed change.
PowerFLEX Users Manual 2-4

Getting Started SETUP program

SETUP program

The PowerFlex SETUP program is located in the system BIOS ROM that sets the system configuration contents in the battery-powered CMOS RAM. The program is similar to the SETUP program on IBM’s AT Advanced Diagnostics Disk. This SETUP program allows the PowerFlex to be a switchless system. The ROM SETUP program provides the following features:
• checks the extended memory and reports its capacity (only on initial setup)
• sets up basic I/O configurations
• provides Shadow ROM/RAM and EMS memory
• recalculates CMOS data and checksums
• shows the presence of a coprocessor (if installed)
Activating the SETUP program
To activate the SETUP program, press the CTRL-ALT-ESC keys at the DOS prompt. Or, if the SETUP configuration is incorrect, the system prompts you to press the F2 key which also activates the SETUP program. The PowerFlex SETUP program is displayed on three SETUP screens. When you first activate the SETUP program, the system responds with the Main SETUP Screen that lists the copyright message, time and date, and current system configurations.
WARNING: The PowerFlex is shipped with the SETUP program having no keyboard or monitor installed. On the Main Setup Screen you must change the “Display” setting to the appropriate monitor (e.g., EGA/VGA, CGA4O, CGA80 or MONO), and the “Keyboard” setting to Installed. On the Third Setup Screen for Soft Switch Options, make sure you also change the “PowerFlex Default Video” setting to Mono or Color (see page 23).
Use the following keys to control the SETUP program:
• The up and down arrows to move the shaded cursor to the appropriate option.
• The right and left arrows to select the appropriate configuration.
• F1 to get help regarding the current entry.
• F10 to exit the SETUP program without saving
• Esc key to reboot the system and save the configurations you’ve just set. After running the
SETUP program, you must boot the system so that the configurations you’ve just set can be recorded in CMOS. If you power down instead of rebooting, the data you’ve
entered will disappear.

Getting Started EMS RAM/ROM SWAP features

EMS RAM/ROM SWAP features

The Second SETUP screen provides the EMS RAM/ROM SWAP features used to configure system memory. The keys work the same way for the second SETUP screen as they do for the main screen.
The EMS RAM/ROM Swap features have been included with the PowerFlex to give you more control over the memory in your system. DOS, the most commonly used disk operating system, is limited to a maximum usage of 640-KB of RAM. A system with DOS installed is therefore restrained to the DOS 640-KB limitation. This means that a system (such as the PowerFlex) that has 1-MB of memory, loses the use of 384-KB (640-KB + 384-KB = 1024-KB; 1024-KB = 1-MB). DOS can only access any memory over 640-KB with the use of an expanded memory driver.
The following subsections explain how the EMS RAM/ROM Swap Screen options allow you to utilize that last 384-KB of memory in the standard 1-MB PowerFlex systems, and how to create and use expanded memory.
Shadow features
Shadowing is comparable to copying a file. For example, when you enable the Shadow Video ROM, video instructions found in this file are shadowed (copied) onto the system’s RAM. This in effect speeds the system up as the CPU will not have to go to the Video ROM BIOS for video instructions and then go back to the RAM for data processing. Instead all instructions will be found in the RAM and can be acted on immediately. The PowerFlex achieves its best performance level by enabling the Shadow ROM features; however, certain expansion cards may not be compatible. When enabling the Shadow features, please follow these guidelines:
• Shadowing is functional only if the 640 - 1024K Relocation feature is disabled
• ALR recommends that you turn Shadow ROM Features OFF for 1-MB memory systems to
free memory for EMS features
• For systems with more than 1-MB of memory, turn the Shadow ROM Features ON. This will
allow the 384-KB of RAM not accessible by DOS to be used by the Shadow BIOS ROM and the Shadow Video ROM which therefore speeds up your system. (See the README file on the Utilities diskette.)
640 - 1024K Relocation feature
The 640 - 1024K Relocation feature opens a gate to allow you access to the 384-KB of memory blocked by DOS limitations by turning it into extended/expanded memory.
Extended memory, simply put, is any memory that is above 640-KB. However, extended memory, which in the case of the standard PowerFlex is 384-KB, is in a protected mode. Only
PowerFLEX Users Manual 2-7
Page 16
Getting Started EMS RAM/ROM SWAP features
software applications designed to use extended memory (such as UNIX and Novell) can access it. To be able to use the 384-KB of RAM in the PowerFlex with software not designed to access it, follow the guidelines below:
• If only 1-MB of memory is installed, this feature, when enabled, allows the additional
384-KB of memory to be accessed and used as EMS, or, expanded memory
• In a 1-MB system, the 640 - 1024K Relocation feature must be used in conjunction with the
EMS Memory feature described below
• If you are going to have more than 1-MB of memory installed in your system, the 640 -
1024K Relocation feature must be disabled
EMS Memory feature
The EMS Memory feature reassigns extended memory as expanded memory to be used with software (such as Lotus 1-2-3) that requires more memory than 640-KB and which can support EMS. EMS is memory beyond 640-KB that is accessed through memory paging. Memory paging, or a reassignment of the memory’s address, is provided in the LIM40 utility program on the PowerFlex Utilities diskette. This utility provides an EMS device driver which enables a DOS system to use expanded memory. (Please see the section entitled LIM4O subdirectory in Chapter 3.) When using the EMS Memory feature, please follow these guidelines:
• EMS Memory, if “ENABLED,” must be used with a physical memory of 1-MB or more
• The 640 - 1024K Relocation feature must be DISABLED whenever the EMS Memory
feature is ENABLED
• The EMS device driver in LIM4O must be activated in conjunction with the EMS Memory
feature
• The EMS Memory Size feature in the EMS ROM/RAM SWAP screen must be changed
(through direct entry as per the instructions in the Activating the SETUP program section earlier in this chapter) to reflect the amount of expanded memory currently resident in your PowerFlex system
EMS Memory Size feature
When you go beyond 1-MB of system memory, you must disable the 640 - 1024K Relocation feature. When you disable the 640 - 1024K Relocation feature, DOS can no longer access 384-KB of the standard 1-MB memory as described previously.
In a standard 1-MB memory configuration, you will see that the EMS Memory Size is 0.5-MB. This 0.5-MB represents the 384-KB of memory that has been converted to EMS memory as explained earlier. When you disable the 640 - 1024K Relocation feature, you lose that 0.5-MB of EMS. Therefore, when you go beyond the 1-MB of standard memory, you must adjust the EMS Memory Size configuration.
PowerFLEX Users Manual 2-8
Page 17
Getting Started EMS RAM/ROM SWAP features
For example, if you have 2-MB of system memory, the EMS Memory Size should read “1-MB.” Remember, EMS memory is any memory above 640-KB. When you disabled the 640 - 1024K Relocation feature, you closed the gate to that extra 384-KB of memory. You therefore now have 0-MB of EMS. When you add a second megabyte of memory to your system, you have 640-KB of RAM and 1-MB of EMS, hence, you change the EMS Memory size to read 1-MB. The following statement will hold true to the maximum memory system configuration of 5-MB — your EMS Memory Size will be 1-MB less than the total system memory configuration.
Memory installation and configuration is further explained in Chapter 4 under the section entitled Memory installation and configuration. This section will describe how to install SIMMs onto the motherboard.

Logging hard disk drive characteristics

ALR recommends that you run the SETUP program to check characteristics of the hard disk installed in your system. Knowing your drive configuration helps if you must set up the system after a crash that destroys the contents of the CMOS. If your system loses its configuration information, check the label on the drive for the drive type or call your dealer.
Appendix B lists all available drive types and their associated characteristics. This list is invaluable if you install a new drive and must define its drive type.
Follow the procedure described in the previous section to display and change the system configuration. Paste a label on your system listing the configurations.
Press F10 to exit the SETUP program. If you have made any changes, make sure that you press ESC to boot the system and save the new system setup.

Using the Utilities Diskette UTIL subdirectory
UTIL subdirectory
The UTIL subdirectory contains the hard disk Park & Ride program, PARKIDE, and a disk­caching program called SpeedRead. The following subsections describe these very important utilities programs.
PARKIDE
PARKIDE is a park and ride program designed to immobilize the hard disk’s head during movement. It basically works on the same principle as a needle return on a stereo. When you use PARKIDE, you lock the hard disk’s head into one position so it can’t damage your data files by skipping across them during transportation. Imagine a needle bouncing across your favorite record, and you’ll know why this feature has been included.
WARNING: The Park & Ride utility program must be activated every time you transport your PowerFlex. ALR recommends that you use this program regardless of the length of distance that the PowerFlex will be moved.
To activate PARKIDE, follow this procedure:
1. Insert the PowerFlex Utility Diskette into drive A:.
2. Type:
A>CD\UTIL <Enter> A>PARKIDE
3. Turn your system OFF. DO NOT touch any keys on your keyboard as this will deactivate
PARKIDE.
4. After you have moved your PowerFlex, to reactivate the hard disk, simply turn your system
back on.
Speed Read
Also included in the PowerFlex subdirectory UTIL is a program called SpeedRead. SpeedRead is a disk-caching program that speeds up the hard disk access rate. As the system is used, SpeedRead monitors how often certain parts of the disk are used and copies the most recently used parts into its internal buffers. If the CPU attempts to read the data again, SpeedRead retrieves the data from its buffers instead of the disk, thus speeding the transfer of data.
To learn more about this program and how to use it, read the README file and the SR.TXT file on the PowerFlex Utilities Diskette in the subdirectory UTIL. The SR.TXT file contains a brief usage guide that will explain how to use SpeedRead. To access the README and SR.TXT files, or to print the SR.TXT file, follow the procedures below.

If you purchase a second hard disk drive through ALR you will receive a high-performance embedded 3-1/2 inch 40-MB <40ms 1:1 interleave hard disk drive that supports one type of drive parameter configuration: 17 sectors, 5 heads, 977 cylinders.
If you choose to purchase one of these optional drives as a second hard disk drive, make sure you purchase and/or receive the following:
• An embedded hard disk drive
• Cabling for two-drive support
PowerFLEX Users Manual 5-2
Page 33
Options Storage devices
• A user’s manual for the second embedded hard disk drive detailing its installation and
configuration
Installing and configuring an embedded hard drive
If you install a second embedded 40-MB hard disk drive, both drives may be accessed via a common two-drive interface cable using the same range of I/O addresses. The drives are jumpered as drive 0 or 1 and have a master/slave relationship. Drive 0 is the master drive, and drive 1 the slave. In a single drive system, no jumper is required; the unit will default to drive 0. In a two drive system, drive 0 should be jumpered as “master” and drive 1 should be jumpered as “slave.”
Figure 5-2 shows how to install an AT-interface embedded hard disk drive into a PowerFlex chassis. Connect the 40-pin ribbon cable between the hard disk drive housing and the JP7 connector on the PowerFlex 286 motherboard. Be sure to align pin 1 (same side as red piping) on the cable to pin 1 (where the notch is) on the connector. If a second hard disk drive is installed, it must be daisy-chained to the first hard disk drive via the 40-pin connector on the above mentioned cable.

Error Messages Fatal system board error beep codes

Fatal system board error beep codes

If an error occurs when the monitor is not available to display the message, the self-test issues a series of beeps to signal the error. The self-test does not issue a beep if a test is aborted while in progress.
For example, a failure of bit 3 in the first 64-KB of RAM causes a 2-1-4 beep code (a burst of two beeps, a single beep, and a burst of four beeps). Additionally, the self-test writes a value to I/0 port 08H. This code enables debugging tools to help technical users identify the failed area.
Errors are either fatal (those that halt the system) or nonfatal (those that are not serious enough to halt the system). Fatal errors contain the word “failure”.

Appendix E, Low-Level Formatting

THE HARD DISK DRIVE HAS BEEN LOW-LEVEL FORMATTED AT THE FACTORY. DO NOT PERFORM THIS PROCEDURE UNLESS YOUR HARD DISK HAS CRASHED.
The HDFORM subdirectory of the utilities diskette contains the WDFMT program which is a versatile formatting utility for performing a low-level format of the high-performance drives.
Follow the procedures below for performing a low-level format on your hard disk drive:
1. Insert the setup/utilities diskette in Drive A.
2. Access the HDFORM subdirectory and view the README file by entering
A>CD\HDFORM<Enter> A>DIR <Enter> A>TYPE README <Enter>
3. Execute the WDFMT program by entering
A>WDFMT <Enter>
4. Use the parameters listed in Table E-1 as responses to the menu.
Table E-1: WDFMT Parameters List
ENTER THIS VALUEPARAMETER
Model 40
Drive (0/1) 0 Cylinders 977 Heads 5 Sectors 17 Interleave 1 Precomp 300 Skew 0 Alt Sector No
5. After the low-level format is completed, the system displays several prompts. Respond to the
prompts with the bolded items, as follows, replacing the <CYD#> and <HEAD#> with the actual cylinders and heads that have been marked as bad on the label on your hard disk drive.

Glossary

386/486 Feature Connector
An ALR designed 104-pin connector that when used in conjunction with the ALR PowerFlex 386SX or i486 Module, automatically upgrades the standard PowerFlex 286 system into a 386SX or i486 system.
387SX math coprocessor
A chip, supported by the PowerFlex 386SX Module, whose task is to do computations in mathematics-intensive applications so as to eliminate this activity and its associated overhead from the CPU. Applications packages must be specifically written to support the 3875X coprocessor.
80286 microprocessor
A 16-bit microprocessor used as the CPU of the PowerFlex.
80287 coprocessor
A chip, supported by the PowerFlex, whose task is to do computations in mathematics­intensive applications so as to eliminate this activity and its associated overhead from the CPU. Applications packages must be specifically written to support the 80287 coprocessor.
base memory
Memory between 0 and 640-KB in which most DOS applications are run.
byte
The basic unit of measure for computer memory. For example, a character uses one byte of memory. Each byte is made up of 8 bits.
CMOS
Complementary Metal-Oxide Semiconductor. The memory that stores the configuration
information entered when you run the SETUP program. CMOS memory uses almost no power.
CONFIG.SYS
A file on the boot disk that configures MS-DOS.
PowerFLEX Users Manual GL-1
Page 57
Glossary
default
The way a switch or jumper is set at the factory.
directory
A list of distinct files containing the names and locations of all the files in a disk. Directories are useful for locating files.
DISKCOPY
A DOS command that copies the contents of the diskette in the source drive to the diskette in the target drive. The target diskette is formatted, if necessary, during copy.
DOS
Disk Operating System. Software used by personal computers that controls the execution of
programs such as resource allocation, scheduling, input/output control, and data management. There are several versions of DOS such as MS-DOS and PC-DOS. The PowerFlex system uses MS-DOS but is also compatible with PC-DOS.
DMA
Direct Memory Access. A method of transferring data between main memory and peripheral devices without processor intervention.
EPROM
Erasable Programmable Read-Only Memory. A storage device whose contents can be
changed by electrical means. EPROM's can be reprogrammed repeatedly.
expanded memory
Memory beyond the 640-KB limit that is accessed through memory paging.
extended memory
Memory above 1-MB.
FDISK
A DOS command that allows you to create, set up, display, and delete the DOS partitions on a fixed disk.
FORMAT
A DOS command that initializes the disk in the designated drive to a recording format acceptable to DOS. It also analyzes the entire disk for any defective tracks and prepares the disk to accept DOS files by initializing the directory.

Glossary
interleave
The number of fixed disk drive revolutions required to read/write one track of data. How sectors are read directly affects the data transfer rate of a disk. For example, a 3:1 interleave requires at least three complete disk revolutions to read/write an entire track of data. Similarly, a 1:1 interleave can read/write an entire track of data in just one disk revolution.
I/O
Input/Output. Refers to peripheral devices such as keyboards or printers.
jumper
A wire (usually encased in plastic) that electrically connects wires on a jumper block.
jumper block
A set of bare (uninsulated) pins on a circuit board.
kilobyte (KB)
1,024 bytes
logical drive
A portion of memory or of a storage device which is perceived and treated as an independent physical drive by the computer’s logic. A partition of a physical fixed disk drive or a virtual drive can be referred to as a logical drive.
low-level formatting
Synonymous with hard disk formatting. This is usually done at the factory. The hard disk drive must be low-level formatted before performing a partition (FDISK) and high-level format (FORMAT).
megabyte (MB)
1,024 kilobytes
MFM
Modified Frequency Modulation. A coding scheme which uses magnetic flux-field reversals
to store data.
POST
Power-On Self Test. A test performed by the computer upon boot-up. The POST checks system integrity.
