1.0 Introduction
Congratulations on your decision to purchase mega mate, the easy-to-install 3.5
inch drive for PCs, XTs, ATs, and compatibles. This manual provides information
regarding the installation and use of both megam ate and mega1nat e 2. 8. Follow
the appropriate instructions for the model you have. Both mega mates give you
diskette compatibility with IBM PS/2 and laptop computers using 3.5 inch
diskettes.
As personal computers have evolved there have been many changes in the type of
diskettes used for storage. The introduction of laptop computers and the IBM PS/2
series has us hered in the use of 3.5 inch diskettes. While they do have their
advantages, 3.5 inch diskettes pose a problem for the existing base of computers
using 5.25 inch drives. Mega mate solves this problem by providing a 3.5 inch
disk drive for your computer. Both megam ates let you use 1.4MB PS/2 and
nOKB laptop formats in your PC, XT, or AT. Mega mate 2.8 lets you use 2.8MB
3.5 inch diskettes too.
Before you start the installation of mega mate, take just a moment to read about
the conventions used in this manual.
1.1 Conventions Used in This Manual
To make reading this guide a little easier, we have clarified certain conventions
and phrases:
• ".J" means that you should press the RETURN or ENTER key.
• When acommand to the computer is shown, your inputs will appear
in boldface.
• PCDOS and MSDOS are functionally the same operating system.
If the system comes with an IBM computer, it's called PCDOS; if
itcomes with acompatible model, it'scalled MSDOS. We will refer
to them both as DOS.
• Your computerneeds
to have a special type of disk to load the DOS
operating system after the power is turned on. We will refer to this
type of disk as a "DOS system disk." It must contain at least the
DOS operating system, and it probably has one or two more utility
programs on it.
If your computer loads DOS from a hard disk, the
hard disk is considered your "DOS system disk."
Introduction -

1.2 System Requirements
Check the system requirements listed here to make sure that you have everything
needed for proper operation
of megamate:
• IBM PC, XT, AT , or 100% compatible computer with:
o 128K memory
o DOS version 2 or above
o One half-size expansion slot
1-2 Introduction
2.0 Installation
The megamate card and software must be installed in your computer before you
can use the
megainate drive. The step-by-step instructions in Sections 2.1 and
2.2 will help you perform the installation.
If you are experienced at installing cards
and software, you may wish to follow the quick start instructions listed
in Appendix
A.
2.1 Card Installation
Installing the megamate card is a straightforward process. It consists of plugging
the card into one
of your computer's existing expansion slots and making sure that
some jumper blocks on the
megamate card are positioned properly. The
instructions
in this section will guide you step by step through the installation
procedure. Perform the following steps to install the
megamate card:
1) With the power off and the computer unplugged, remove any screws
necessary to allow you to get access to the expansion slots in your
computer.
2) Make sure the interface card is set according to the following table:
megamat e megamate 2.8
J1=A J1=C
12=B 12 = INT 6 and both DMA 2 jumpers
J3=A
14=A
15 =B
16 = B
SWI switches 2 & 5 ON, all others OFF
SW2 switches 5 & 6 ON, all others OFF
3) Find an available expansion slot. If there is a blank metal face plate on
the back
of the computerimmediately behind the slot, remove it and save
the screw. Seat the
megamate card squarely and firmly into the slot in
such a way that its mounting bracket lines up with the mounting hole in
the cabinet. Screw the megamate mounting bracket down securely.
(Don't use the slot next to the power supply on IBM XTs.)
4) Putthe cabinet back together and replace any screws that were removed.
Connectthe powercable and anythingelse you mighthave disconnected.
Installation

5) Plugthe mega mate drive into the megam ate card. Screw the retaining
screws in finger tight. Be sure the power is off whenever you connect or
remove the
mega mate drive.
Once you have completed the installation successfully, yourcomputershould work
exactly as it did before. If it doesn't, review the installation procedure and check
for mistakes. If the problem persists, refer to Appendix B (Troubleshooting) to try
to isolate the cause.
2.2 Software Installation
The MEGAPREP program will install the megamate software for you
automatically. Use the following procedure to run MEGAPREP:
I) Tum on your computer and insert your DOS system diskette. Wait for
your computer load DOS.
2) Place your mega mate master diskette into drive A. Make su re that you
have your DOS system prompt "A" before you proceed to the next step.
3) Run the MEGAPREP program with the following command:
A>megaprep.J
Follow the instructions given by the MEGAPREP program.
4) The
megamate di skette contains a file called PRINT.ME, which has
been copied to your DOS diskette. PRINT.ME contains information
gathered since this guide was printed. Use the following command
to
print this file on your printer:
A>copy print.me prn:.J
The megamale software should now be installed on your DOS system diskette.
Remove the megamate masterdiskette and put it in asafe place. You must re-start
the computer to activate the megamate software. Either power the computer off
and then back on or hold down CTL-AL T and press DEL on the keyboard.
2-2 Installation
3.0 Using Megamate
Megamate is usedjustlike yourotherfloppy disk drives. Ithas i ts owndrive letter.
You can access it from your programs by referring to the drive letter. The DOS
utilities DIR, COPY, CHKDSK, CD, MD, RD, etc. can be used with megam at e.
The DOS commands FORMAT, DISKCOMP, and DISKCOPY will work with
megamat e .if you are running DOS version 3.2 or above. The MMFORMAT
command provided with
mega ma te can be used with DOS versions 2.0 or above.
3.1 Megamate's Drive Letter
Just as your primary floppy drive is referred to by the letter A, megamat e also
has a drive letter associated wi th it. The actual letter to be used is assigned by DOS
and is determined by which letters are already in use on your system. Megam ate
will get the next available letter in alphabetical order. Forexample, ifyou have two
floppy drives, using letters A and B, megama te will be drive C. In a typical hard
disk system where the floppy drives are A and B and the hard disk is C, mega mate
wi ll be drive D.
When your computer
is powered up, a message will appear on the screen to tell
you the megam ate drive letter. The message wi ll look like the following:
The following Megamate dri ve is available :
DriveD : - 3 . 5 inch High Capacity
In this case, you would refer to megam ate as drive D when accessing it via any
software packages.
Youcancheck the megama te drive letterat any time by entering theMMDRIVES
command. Invoking MMDRIVES will cause the drive letter message to be printed
on the screen. (Be sure the MM DRIVES.COM program is on your disk before you
invoke MMDRIVES.)
Usina Meaamate 3-1

3.2 720KB, 1.4MB, and 2.8MB Disks
There are now three 3.5 inch disk formats for IBM and compatible computers. One
is the nOKB format which is used by the IBM iaptop computer and several other
laptops. Another popular diskformat is the IAMB high-density format introduced
on the PS/2 model 50 and higher-level models. The PS/2 models that support the
1.4MB format are also capable of using the nOKB disks. The 2.8MB format is
new and at the time of this writing has not been available from IBM. 2.8MB drive
upgrades (like megamate 2.8) are also capable of using the IAMB diskettes and
the nOKB diskettes.
Megamate will automatically sense the format of the disk being used, whether it
is nOKB, 1.4MB, or2.8MB and adjust itselfaccordingly. The only time you have
to select a format is when initializing a new blank disk to one of the three formats.
High-density diskettes can be easily distinguished from double density diskettes
because they have an extra hole molded into the case. Holding a 3.5 inch diskette
in your hand with the spindle hole facing down and the access door facing away
from you, the write protect hole will be in the left hand comer nearest you. If the
disk has a similar hole in the righthand comer nearest you, it is a high-density disk.
Extended Density diskettes, used for the 2.8MB format, have two holes molded
into them, just like high-density diskettes. They will also have an
"ED" printed on
them to signify that they are extended density.
3.3 Initializing Disks
Brand new diskettes are blank and must be initialized to the nOKB, 1.4MB, or
2.8MB format before they can be used. Diskettes that have already been used can
be re-initialized as a way of completely erasing them.
High-density 3.5 inch diskettes are actually a different type
of diskette than the
double-density variety. Diskettes should only be initialized to the format for which
they were intended. Initializing double-density diskettes to 1.4MB format will
result
in unreliable operation, as will initializing high-density diskettes to nOKB
format. The same holds true for extended density diskettes.
Two programs are included for initializing diskettes with
megamate :
MMFORMAT and BACKFMT. MMFORMAT is a command line driven disk
initialization utility, similar in usage to the DOS FORMATcommand. BACKFMT
is a "pop-up"disk initializer that can be used in the background while you continue
working on another application.
3-2 Usin Me amate
3.3.1 MMFORMAT
Syntax
MMFORMAT drive letter options
Purpose
MMFORMAT is a diskette initialization utility for use only with your
megamate drive. Similar in use to the DOS FORMATutility, MMFORMAT
allows you to initialize blank diskettes into all DOS 3.5 inch formats.
Options
/no creates a nOKB diskette
/1A creates a 1.4MB diskette
/2.8 creates a 2.8MB diskette
(megamate 2.8 only)
N prompts for a volume label after the diskette is initialized
/S copi~s the operating system files to the diskette after initialization
Description
The drive letter, followed by a colon(:), shou ld be your megamate drive.
The format option determines which format will be used. It consists of a
forward slash (f) followed by three character s. Ifyou enter the MMFORMAT
command without specifying a format option, the highest capacity format
supported will be used. This conforms to the precedent set with the DOS
FORMAT command.
Make sure you have high capacity diskettes if you are trying to use a high
capacity format, orelse initialization errors and dala loss will probably occur.
You may initialize a blank diskette or reinitialize an existing diskette, but
remember that initialization will erase any existing data on the diskette.
For this example, assume that drive D is a megamate 1.4MB drive:
A> mmformat d: /720.J
would initialize the diskette in drive D to the nOKB format.
A> mmformat d: /1. 4 /s.J
would initialize the diskette in driveD to the IAMB high capacityformat used
by the IBM PS/2 computers and place a copy of DOS on the disk, making it
a DOS system disk.

A>mmformat d:.J
would also initialize the diskette in drive D to the 1.4MB high capacity format
used by the IBM PS/2 computers. Since no capacity is specified, the highest
capacity supported for the type
of drive is used.
3.3.2 BACKFMT
Initializes diskettes while other programs are running.
Syntax
BACKFMT options
Purpose
BACKFMT
is a background diskette formatting program that allows you to
initialize diskettes while you continue running other programs.
Options
/C reconfigures some BACKFMT options after the initial installation
ID disables BACKFMT and removes it from memory
Description
Background formatting is initiated when you press a user-definable "access
key," which displays a menu from which you can select the drive and capacity
of the diskette to initialize. After you select the drive and capacity,
BACKFMT will start initializing the diskette while returning you to your
original program. You can conti nu e working while BACKFMT performs the
initialization.
Tomake the background formatter available, you have to run the BACKFMT
program. Enter the following command at the DOS prompt:
A> backfmt.J
Configuration
The first time the BACKFMT program is run, it will display a message
indicating that it has not been configured yet. Configuration consists of
answering a few simple questions. Each question has a default answer (in
square brackets) that can be used for the first-time installation. Listed here
are some points you will be asked about:
• Would you like to change the background formatter access key?
This allows you to change the access key to a different combination
of keys. The access key is initially set to Ctrl-Alt-F.
• What would you like BACKFMT to do when it completes the
initialization
of a diskette? You can select how to be informed when
BACKFMT finishes initializing a diskette.
• Would you like the diskette to be verified after formatting? You
should always have the diskette verified for normal operation. If
you tell BACKFMT not to verify, it will always verify the first
cylinder, where the directory is placed. If that area is good, it will
continue without verifying the re st of the diskette. Turning
verification off allows diskettes to be initialized about 20-30%
faster.
• Are you using a color monitor? You should answer Yes to this
question only if you are really using a color monitor. If you have a
monochrome (white, green, or amber) monitor, answer No. Menu
readability will be improved by a correct response.
Once you answer the configuration questions, the BACKFMT.COM file will
be updated with the new information. From that point on, when BACKFMT
is run, it will not ask for configuration information. Ifyou want to change the
configuration, you should specify the /C option when you are running the
BACKFMT program, as follows:
A> backfmt /c.J
IfBACKFMT is reconfigured with the /C option, all the changes will be made
to the BACKFMT.COM file. The changes will take effect immediately.
The currently defined access key will be displayed near the end of the
BACKFMT signon message. It will look similar to this:
While holding Ctrl & Alt, press F
When the DOS prompt returns, BACKFMT is ready for use. If you need to
removeBACKFMTfrom memory, use the following commandfrom the DOS
prompt:
A> backfmt /d.J
Using BACKFMT
To initialize a diskette with BACKFMT, use the following procedure:

•
1) Press the BACKFMTkey sequence. The default is Ctrl-Alt-F unless you
changed it during configuration. A window displaying the available
drives and formats should appear near the top
of your screen.
2) Using the cursor keys, select the format capacity that you would like to
use.
3) When you have selected the desired format capacity, press ENTER to
get the program to accept your choices.
4) Another window will appear, displaying your selection and giving you
one last chance before the initialization starts. Pressing ENTER will start
the diskette initialization, and you will be returned to the program you
were originally running.
Ifyou press the BACKFMT access key while a diskette
is being initialized, a
status window will appear. The current cylinder and head being initialized
will be displayed
in this window. Press any key to remove the status window.
Depending on how you configured BACKFMT, a window may appear when
the initialization is finished or if
an error exists. This display will be
self-explanatory.
If you configured BACKFMTso it won't display a window,
the result will be displayed when you press the access key again.
Notes
BACKFMT will work only with your megamate drive.
If you attempt to access a diskette that
is currently being background
formatted, you will get a "Drive not ready" error message. The drive will be
accessible as soon as the initialization
is complete.
You may notice the drive light going off on a drive being background
formatted when you access anotherdiskette drive.This is normal because only
one diskette drive can
be used at a time. BACKFMT will give priority to
another program if it
is accessing a diskette drive. When the program seems
to be done with the diskette drive, BACKFMT will continue.
The BACKFMTmenu
is not available while yourscreen is displaying graphic
images.
If you try to access the BACKFMT menu while your display is in a
graphic mode, you wiil hear a beep.
Don't remove BACKFMT from memory with any memory management
program. While
in memory, BACKFMT is closely linked to
MEGAMATE.SYS; and if
it is improperly removed, it will cause system
failure. Remove BACKFMT from memory only with the
(D option.
Appendix A Quick Start
This section is only for experienced installers who don't want detailed instructions.

If there seems to be a problem using the computer or megamate after
installation, read the following problem descriptions to see
if they match those you
are experiencing.
If you can't resolve the problem, call Micro Solutions and ask
for
megamate technical assistance.
B.I Symptoms
When trying to access megamate, an "Invalid drive specification"
message appears on the screen.
This can occur if you are not using the correct drive letter to access
megamate. Be sure the letteryou use is the one indicated on the screen when
the computer loads DOS. Review section 3.1 for information on drive letters.
Thiscan also
occur if you have not run MEGAPREP to install the megamate
software, or if you have notrestarted thecomputerafter running MEGAPREP.
Review section 2.2 for information on software installation.
The activity light on megamate never illuminates. When you are
trying to access megamate, nothing happens. Eventually a "drive
not ready" or other failure message appears.
megamate (1.4MB version only)
This can
occur if the setting of jumpersJ I and]2 on the megamate card
does not match the software configuration. Make sure that you have run
MEGAPREP to install the software. 11 should be in position A and 12
should be in position B for a standard installation. Read Appendix C for
more information on
jumper settings and software configuration.
The activity light on mega mate illuminates. However, when you are
trying to access megamate, nothing happens. Eventually a "drive
not ready" or other failure message appears.
This problem may occur if another card in your computer uses the same I/O
addresses that megamate is trying to use. You may need to try jumpering
the
megamate card for a different address range. Read Appendix C for more
information on
jumper settings and the associated software configuration.
Trnllhh: .. ::hnntinn R_1

megamate 2.8
This problem can also occur because of a DMA channel conflict. Try
selecting
an alternate DMA channel for the megamat e card. Review
Appendix C for information about DMA channels.
The activity light on megamate illuminates at the same time as the
activity light on one of the other floppy disk drives. When trying to
access megamate, nothing happens. Eventually a "drive not ready"
or other failure message appears.
This problem indicates that another card in your computer is using the same
I/O addresses that megamate is trying to use. It will be necessary to jumper
the
megamate card for a different address range. Read Appendix C for more
information on jumper settings and the associated software configuration.
The activity light on megamate illuminates. When trying to access
megamate, the disk rotates. Eventually a failure message appears.
This problem can occur if another card in your computer is using the same
I/O addresses that megamate is trying to use. It may be necessary to jumper
the
megamate card for a different address range. Read Appendix C for more
information on jumper settings and the associated software configuration.
This problem could also occur if you have a disk drive alignment problem.
Either the drive that created
th e diskette or megamate may be out of
alignment. Try initializing a new 3.5 inch diskette on megamate using
MMFORMAT and accessing
it. If it works, one of the drives is probably
misaligned. Try reading your diskettes on a different PC to pinpoint the
problem. Yourlocal servicecentershould beable to perform adrivealignment
for you.
megamate 2.8
This problem can also occur because of a DMA channel conflict. Try
selecting
an alternate DMA channel for the megamate card. Review
Appendix C for information about DMA channels.
After megamate is installed, one of your existing cards, devices, or
programs doesn't work properly.
This problem may occur if another card in your computer uses the I/O
addresses that megamate is using. Remove the megamate card and the
MEGAMATE.SYS software to see ifthe problem goes away.
If itdoes, there
appears to be an I/O address conflict.
If it doesn't, megamate is not the
B-2 Troubleshooting
source of the problem. Read Appendix C and try another jumper option if
necessary.
With megamate installed on an AT&T PC 6300, the activity light il-
luminates when you are trying to access the drive, but megamate
doesn't function properly. Errors in reading or writing occur.
Replace the AMD 9517 DMA controller with an equivalent DMA controller
of another brand. The NEC 8237-5 is known to be agood substitute. The9517
is located on the mainboard of the computer and will require a computer
service technician to replace
it.
Alternately, you can try the following solution:
megamate (1.4MB version only)
Use the NODMA option. After you have completed the hardware and
software installation
of megamate , use your text editor or word
processor to edit the CONFIG.SYS file on the disk drive that
MEGAMATE.SYS was installed to. Locate the line that contains the
statement"DEVICE=MEGAMATE.SYS". Add a blank space to the end
of the line and then add NODMA. Your edited line in CONFIG.SYS
should look something like:
device=megamate.sys /08,7,3 NODMA
megamate 2.8
Try selecting an alternate DMA channel for th e megamate card.
Review Appendix C for information about DMA channels.
The MMFORMAT and MMDRIVES commands don't work. Invoking
them results in a "Bad command or file name" message.
The MMFORMAT.COM and MMDRIVES.COMfiles are not located on the
di sk you are trying to access them from. For either command to be used, the
files must be located on the
di sk you are invoking them from. After you run
MEGAPREP, the files will be located on your DOS system floppy diskette or
in the root directory of your DOS system hard disk. You may copy them to
another floppy diskette or to the utilities subdirectory
of your hard disk by
using the DOS COPY command. You may wish to experiment with the DOS
PATH command to make your computer find them automatically.
TrnlJhl~~hnntinn R-~

The MMFORMATand MMDRIVES commands don't work. Invoking
them results in the following message: "The megamate device
driver 'MEGAMATE.SYS' is not installed."
The megamate controlling software was not installed on your DOS system
disk. The CONFIG.SYS file on your DOS system disk may have been
modified or deleted, eliminating the reference to
megamate . The
MEGAMATE.SYS file on your DOS system disk may have been deleted.
If
either of the above is true, you must perform the software installation
procedure again. Refer to section 2.2
of this manual for instructions.
The message will also occur ifyou loaded DOS from a DOS system disk other
than the one
megamate was installed on. (For example, you might have
loaded DOS from a floppy diskette after installing
megamate on your hard
disk, or you might have used a DOS floppy diskette other than the one
megamate was installed on.) In this case, restart your computer using the
proper DOS system disk.
The activity light on the drive goes on. You are able to initialize a
diskette with MMFORMAT, but when you try to use the diskette you
get a "Non DOS disk" error.
This can occur if there is a DMA channel conflict between the megamate
card and something else in your computer.
megamate (1.4MB version only)
Use the NODMA option. After you have completed the hardware and
software installation
of megamate, use your text editor or word
processor to edit the CONFIG.SYS file on the disk drive that
MEGAMATE.SYS was installed
to . Locate the line that contains the
statement"DEVICE=MEGAMATE.SYS". Add a blank space to the end
of the line and then add NODMA. Your edited line in CONFIG.SYS
should look something like:
device=megamate.sys /08,7,3 NODMA

is interfering with it. Move the 12
interrupt jumper to another setting (2 through 7) and try again. This
problem could also occur
if no interrupt was jumpered. You must select
oneand only one interrupt. Referto section C.2.5 for further information.
Troubleshooting 8-5

CC4: You have a bad or upside-down cable.
During its self-test, the megamate 2.8 card determined that a drive
cable is either shorted
or plugged in backwards. Check your cables
carefully.
The same message will occur ifa drive that is properly connected to the
megamate 2.8 card does not have DC power connected to it. Check
your
DC power connections.
This error could
al so occur ifan I/O conflict exists with another card in
your system. If you still g et this error with no cables connected to the
megamate 2.8 card, try using a different card address.
8-6 Troubleshooting
Appendix C Card Options
Your computer communicates with the megamate card through some electronic
Input/Output locations called "I/O ports." The I/O ports on the
megamate card
can be electronically located at one
of three different "addresses."
Your existing disk controller uses I/O ports also, as do most other cards in your
computer.
If two or more cards try to use the same I/O port address they will
conflict, which will preventproperoperation.
By allowingyou to selectone of three
different addresses for the
megamat e card we can prevent conflicts with cards
already
in your computer.
Megamate is shipped to you with the address selected the way that works with
most computers.
If you experience problems using megamate which seem to be
related to an I/O port conflict, you will need to try one
of the other two
configurations. Please note that while there are actually four possible
configurations,one
of them is reserved because it wouldconflictwith yourexisting
disk controller.
The following sections provide further details on the configuration options
available on the interface card.
e.1 Jumper Settings (1.4MB version)
The megamate software needs to know what I/O port addresses the card will be
using. MEGAPREP sets up your software assuming that the jumpers are in the
factory-set position.
If you select a different address position you will need to run
MEGAPREP again and tell it so.
Setjumpers J1 and J2 on the
megamate card to correspond to one of the optional
positions in the table below. Next, run the MEGAPREP program again using the
following syntax:
MEGAPREP.J
MEGAPREP will ask you for the position
of jumpers J1 and 12. MEGAPREP will
make the necessary changes to the CONFIG.SYS file on your DOS system disk to
reflect the
jumper changes.

C.2 Card Options (2.8MB version)
The megamate 2.8 card has several options that you may wish to take advantage
of. In addition
to being able to change the card address to avoid address conflicts,
you may also change the DMA channel and interrupt number to avoid conflicts
of
those types. You may also allow yourcomputerto bootfrom the megamate drive.
It is even possible to add up to three more drives to the card.
The
megamate 2.8 card is also sold separately as the CompatiCa rd IV floppy
controller. This section contains a condensed version
of the CompatiCard IV
documentation that should be sufficient to allow the use of the additional features
of CompatiCard IV . The complete CompatiCard IV documentation and a
software diskette can be purchased from Micro Solutions for a nominal fee. Read
the following sections to learn how to make the most

C.2.2 Card Address (Jl)
You must set jumper J1 to one of three positions (B through D) that sets the
electronic "address" that the computer uses to communicate with
CompatiCard
IV.
Positions B, C, and D select Secondary Controller addresses. Use anyone of these
settings. Three choices are provided to avoid interference with other add-on cards.
You may use any
of the three that works in your computer. Position C is known to
work
in most brands of computers. Table C-4 lists the I/O port addresses used for
each J1 setting.

Table
C-4 I/O Ports Used
Place the jumper block on the pins corresponding to the address you wish to use.
Write down the setting you choose. You may need to refer to
it during software
installation.
Suppose you have installed
Compati Card IV as a Secondary
Controller but
it does not work. After reading the section on
troubleshooting, you conclude that the problem may be from another
card
in the computer trying to use the same electronic "address". Set
11 to a different secondary address (B, C, or D) and try again.
C.2.3 BIOS Address (SWl-l, 2, 3)
You must set the address the computer will use to read the BIOS ROM. This is
done by setting switches 1, 2, and 3 on switch bank SWI to correspond to the
desired address.
Choose
an address location from the following table and set the switches
accordingly. The factory setting has been found to work well
in many computers.
Depending on what other cards are installed
in your computer, you may have to
select another option. The symptoms
of a BIOS address conflict will be that
Compati Card IV does not access the floppy drives properly, the computer does
not load DOS, orone
of your other cards will not function when this BIOS address
is selected. In any of these cases, try another switch setting. Always tum the power
off before you make a switch change, otherwise the computer will lock up.
If you are unable to find a BIOS address that works for you, you will have to use
the NOROM option. Set the switches according to the table and use the NOROM
option (see section C.2.11) when installing the device driver software. When the
NOROM option is used, the auto boot feature will no longer work, You will also
lose the ability to boot from certain types
of drives.

Table C-5 BIOS Address Switch Settings
To perfonn a nonnal first-time installation of Compati Card IV you would use the
factory setting of the BIOS address. Make sure that SWI positions 1, 2, and 3 are
set to OFF, ON, OFF respectively.
Suppose you have
al ready perfonned the installation and your
computer exhibits the symptoms of a BIOS address conflict (won't
boot or locks up). Try another BIOS address setting. Tum off the
power to your computer and set SW1 switches
1,2, and 3 to one of
the other six address choices.
You may have tried all
of the BIOS address options with no success.
Either the problem is not with the BIOS address or else your
computer has no BIOS space available. Try using the NOROM
option. Set switches SW 1 1 ,2, and 3 to the OFF position. Install the
NOROM software option as explained in section C.2.II of this
manual. IfNOROM doesn't solve your problem,
it is not a BIOS
address problem.
C.2.4 DMA Channel Selection (J2)
You must select the DMA channel to be used. This is accomplished by positioning
both jumper blocks to the corresponding DMA channel position on header
connector 12 on the card and by appropriately setting switches 5 and 6 on switch
bank
SWI.
Choose the appropriate DMA channel number (1 ,2, or3) from table C-6 and move
both DMA jumper blocks to the correct numbered position on header 12. Set
switches SWl -5 and SWl-6 to the position corresponding to the selected DMA
channel. This indicates to the BIOS software which channel is in use. For most
applications the correct
DMA channel will be 2.

3 3 ON ON Optional in PC, AT only-not XT
2 2 OFF OFF Must also jumperfor Interrupt 6
Table C-6 DMA Channel Switch and Jumper Settings
SWl-5 off and SW1-6 off is a specialcase that should be used only as a last resort.
When both switches are off, the DMA channel must bejumpered for channel 2 and
the interrupt must be jumpered for 6 on header 12 of the card. This option defeats
the automatic sensing
of which interrupt is being used. It has been provided for use
when interrupt sensing does not work. It should not be necessary in most cases.
DMA channel 2 will not work on a few types of computers. If it doesn't work, the
computer will appear to function nonnally but operations involving disk access
using CompatiC ard IV will fail. If your computer shows this symptom, try one of
the optional DMA channels.
Suppose you have installed
Compati Card IV using DMA channel 2
and your computer will not access the drives properly. After reading
the section on troubleshooting you decide
it may be a problem with
the DMA channel. You have
an IBM AT. From Table C-6 you see
that you may select either DMA channel I or DMA channel 3. Do so
and try again. Set the
12 DMA jumpers to the new channel setting
and set
SWI-5 and SWl-6 accordingly.
Suppose you have installed
Compati Card IV using DMA channel 2
and your computer will not access the drives properly. After reading
the section on troubleshooting you decide it may be a problem with
the DMA channel. You have an IBM XT. From the DMA Channel
Selection table you see that you may select DMA channel I
as an
alternate. Set the 12 DMA jumpers to the channel I setting and set
SWI-5 OFF and SWI-6 ON.
Suppose you have installed Compati Card IV using DMA channel 2
and your computer will not access the drives properly. After reading
the section on troubleshooting you decide
it may be a problem with
the DMA channel. You have a PC compatible. You may select
either DMA channel 1 or DMA channel 3 and try again. Set the 12
DMAjumpers to the new channel setting and set SWI-5 and SWl-6
accordingly.

C.2.S Interrupts (J2)
You must select the interrupt number to be used when the floppy controller
communicates with the computer. This is done by placing a jumper block on the
position corresponding to the desired interrupt on header connector 12 of the card.
For almost all computers, the correct setting will be 6. If interrupt 6 does not work
in your PC, move the jumper to one of the other five optional positions until you
find one that does.
If the selected interruptdoes not function with Co mpatiCard IV in yourcomputer,
a message will print on the screen telling you that there is an interrupt conflict.
The interrupt number
in use is automatically sensed by the BIOS software when
the power is turned on. If you are unableto make any combination ofDMA channel
and interrupt work
in your computer, try using DMA 2 and interrupt 6 with SWl-5
off and SW 1- 6 off. Th is unique setting defeats the automatic sensing of interrupts.

After you install Com pa tiCard IV, if a message appears on your
screen indicating an interrupt conflict, you must change J2 to another
interrupt position. Move J2 to a different interrupt position and try
again.
If you have tried all of the interrupt positions but still get the message
about an interrupt conflict, it is possible that the automatic sensing of
interrupts doesn't work on your computer. Try using interrupt 6 and
DMA channel 2 with SWl-5 OFF and SWI-6 OFF. This special
setting defeats the automatic sensing of interrupts.
C-8 Card ODtions
C. 2.6 Dual Sp eed Drives (S Wl - 7)
Youmustset switch SWl-7 to correspond to the type of 1.2MB drive you are using.
There are two popular types
of 1.2MB drives available. The original type used in
the AT has only one spindle speed of 360RPM; 360KB density and 1.2MB density
are achieved by using data transfer rates of 300Kbps and 500Kbps respectively.
Almost all aftermarketdrives have two spindle speeds available, 300RPM and 360
RPM. With a dual speed drive the data transfer rates to achieve 360KB and 1.2MB
densities would be 250Kbps and 500Kbps. Co mp a ti Card IV can handle both types
of drives properly but needs to be told which type has been installed. Set switch
SW
1- 7 according to the following table.
1.2MB Drive Type
SWI-7
Notes
Single speed OFF Factory Setting
Dual speed ON Optional
Table C-8 1.2MB Drive Spindle Speed Switch Settings
Most 1.2MB drives beingsold today can operate
in eithersingle speed ordual speed
mode. The mode of operation is controlled by ajumperblock orswitch on the drive
electronics board. It is common for these boards to be shipped jumpered for single
speed operation. This is a good guess to start with if you don't know which kind
you have.
The symptoms of having SWI-7 set improperly will be that you can read 1.2MB
disks but not 360KB disks. You must restart your computer after changing switch
SWl-7.
If you have achoice, use your 1.2MB dr ives in single speed mode.You will acheive
faster data transfer on 360KB disks.
Let's assume you are installing Com p at iCard IV and one of the
drives attached to it will be a single speed 1.2MB drive. In this case
you will set switch SWl-7 to the OFF position.
Perhaps you are installing Compat i Card IV in a computer with a
dual speed 1.2MB drive, a 360KB drive, and a nOKB 3.5 inch drive.
In this case, because the 1.2MB drive is a dual speed drive, you will
set switch
SWl-7 to the ON position. It does not matter which other
types of drives are connected.
As another example, assume you have installed Com pati Card IV in
a computer with what you believe is a dual speed 1.2MB drive and
you have set switch SWI-7 to the ON position. You find that you are
able to read 1.2MB diskettes but cannot access 360KB diskettes.
This will occur
if the drive itself h as been jumpered for single speed
operation. Try setting switch SW
1-7 to the OFF position.

C.2.7 Auto Boot (SWl-S)
You must decide if you want Compati Card IV to load DOS from any drive
attached to
it that has a disk in it. Switch SW 1-8 must be set appropriately.
CompatiC ard IV has the unique ability to be able to boot from more than one
floppy drive. In fact, it will try to boot from the first drive it checks that contains a
diskette. This feature is usef
ul for people who usually boot from one type of disk
but wish to boot from another type on occasion (e.g. who normally boot from
360KB 5.25 inch diskettes but sometimes boot from
nOKB 3.5 inch diskettes).
Use the following switch settings to control the Auto Boot feature.
Auto Boot
SWI-8
YES ON
NO OFF
Table C-9 Auto Boot Feature Switch Settings
When Auto Boot is enabled, Compati Card IV will check each drive for about 1
second, looking for a DOS system disk.
If none is found, your computer will
proceed toboot
in its normal fashion. If aDOS system disk is found, Compati Card
IV will boot from that drive. The drive that Compati Card IV boots from will
become drive A for the duration
of that computing session. This is desirable since
most diskettes that contain DOS have been configured to run as drive
A. The drive
that
is normally drive A will be assigned drive 16 and unavailable for the duration
of the session. For this drive to be accessed, the DOS DRIVER.SYS file (DOS
Version 3.2 and above) must be invoked at boot time to assign drive 16 a letter.
If your application is such th at you need to access what is normally the A drive
after using the Auto Boot feature, perform the following steps:
1) Copy the DOS DRIVER.SYS file to the diskette you will boot from.
Make sure it is the same version as the DOS you will be booting.
2) Add a line to the CONFIG.SYS
fi le on the diskette you will boot from
to include a reference to DRIVER.SYS. (Create the CONFIG.SYS
fi le
if it doesn't already exist.) Select the appropriate line from table
6-4,
depending on which type of drive is normally your A drive:
Drive Type Add to CONFIG.SYS
5.25 inch 360KB device=driver.sys Id:

Table
6-4 DRIVER.SYS Commands to Retain Drive A after Auto Boot
Assume your computer has one 360KB drive and you use
Compati Card IV to add a 2.8MB 3.5 inch drive. At some point you
wish to boot from a 3.5 inch diskette but you want to retain the use
of
the 360KB drive. To do so, you will need to copy DRIVER.SYS to
the 3.5 inch diskette. Then you will need to add the following to the
CONFIG.SYS file on the 3.5 inch diskette:
device=driver.sys Id:
16 1f:0 It:40 Is:9 /h:2
When you boot from the 3.5 inch diskette, your 360KB drive will be
accessible as drive C (or the next available letter on your system).
Let's assume that your computer has a 360KB 5.25 inch drive as
drive
A. You want the 360KB drive to be drive A except when you
occasionally boot from a 3.5 inch system disk. You have installed a
2.8MB 3.5 inch drive connected to
Compati Card IV. In this case
you should set switch SW
1-8 to the ON position. Compati Card IV
will check the 3.5 inch drive for the presence of a diskette each time
you boot your computer.
If a DOS system disk is present, your
computer will boot from the 3.5 inch diskette and the 3.5 inch drive
will become drive A until the next time DOS
is loaded.
Let's assume that you have installed
Compati Card IV with several
drives attached. You
don't want Compati Card IV to boot from
drives other than your normal drive
A. Set switch SW1 -8 to the OFF
position. This will disable the Auto Boot feature.
C.2.S External Power Jumpers (J3, J4, J5, J6)
You must set the jumper blocks 13, J4, J5, and J6 to the appropriate po si tions in
order to enable DC power on the external DB-37 connector P4. Set 13 and J4 to
position
A, J5 and J6 to position B.

C.2.9 Drive Types (SW2)
You must setthe switches on switch bank SW2 thatcorrespond to each of thedrives
attached to
Co mpatiCard IV. For each of the four possible drives there are two
switches to set.
Co mpat iCard IV follows IBM's conventions for disk drive cable wiring and
addressing. All drives attached should have their drive select jumper set to the
second drive position (e.g.,
DSI ifthe sequence is DSO, DSI, DS2, DS3; and DS2
if the sequence
is DSI, DS2, DS3, DS4). Each drive connector is capable of
handling two floppy drives. The low-order/high-order addressing of the drives is
determined by the type
of cable used for the connection. A cable connector that has
wires
10 through 16 twisted overconnects to the low-order drive; a cableconnector
in which wires
10 through 16 run straight through connects to the high order drive.
Many internal drive cables have both the low- order and high-order connector on
them.
The
megam ate 2.8 drive is connected to P4 using a twisted cable wiring. Be sure
SW2-5 and SW2-6 are both ON.
Compati Card IV supports up to four drives. Use table C-II to determine the drive
position numberfor each
of thedrives you will beconnecting. Write down the drive
position number; you'
ll need it later for software setup.

Table C-II Drive Position Numbers and Drive Type Switch Settings
Thesetting for both 360KB and 1.2MB 5.25 inchdrives is the same.
Compati Card
IV will automatically determine which type of 5.25 inch drive you are using. If you
C-12 Card ODtions
are using a 3.5 inch IAMB or 2.8MB drive, set the switches accordingly. For all
other drive types (e.g.,
nOKB and 8 inch) or when no drive is in use, set both
switches OFF.
If you connect a 1.2MB 5.25 inch drive to connector P2 of
Compati Card IV using a twisted cable, you will use the preceding
tables to find that the drive position number is
O. Using this
information you find that you should set switches 1 and 2 on SW2.
Since you have a 5.
25 inch drive, set SW2-I OFF and SW2-2 ON.
Perhaps you have connected a 360KB 5.25 inch drive to connector
P2 of Compati Card IV using a straight cable and you have
connected a 1.4MB 3.5 inch drive to connector P2 using a twisted
cable. Using the preceding table you find that the drive position
number for the 5.25 inch drive is I. The drive position number for
the 3.5 inch drive is
O. You then find that you should set SW2-I ON,
SW2-2 OFF, SW2-3 OFF, and SW2-4 ON.
C.2.10 Drive Cable Connections (P2, P3, P4)
Co mpati Card IV has three disk drive connectors to accommodate a variety of
cable configurations. Two of the connectors are for internally mounted drives. The
third is for externally mounted drives. Each connector has a name associated with
it (P2 to P4). The name is printed on the card near its associated connector. Table
C-12 describes each connector and the drive positions associated with it.
Connector Drive Drive
Designation Positions Location Connector Type
P2 0& 1 Internal 34 Pin Header
P3 2&3
Internal 34 Pin Header
P4 2&3
Exte rn al DB-37 (female)
Table
C-I2 Connector Designations
When you are installing cables for internally mounted drives, make sure the pin I
side
of the cable (usually marked with a colored stripe) is connected to the side of
the connector that is marked "1." On all Compati Card IV internal disk drive
connectors (P2 and P3), pin I is toward the top
of th~ card.
Connector P2 may be used
fo r drives in drive position 0 or 1. Connectors P3 and
P4 may be used interchangeably fo r drives in drive position 2 or 3.
f'<>rrl nnt i nnc> "" _1 ':t

Be careful not to connect a drive with a twisted cable to P3 while the megamate
2.8 drive is connected to P4. Since the megamate 2.8 drive is always given
position 2, this would assign drive position 2 to both drives. You may not have two
drives with the same position number.
C.2.II The NOROM Option
Your computer uses the MEGAMATE.SYS device driver to access the
Co m patiCa rd IV drives. The MEGAMATE.SYS device driver uses the ROM
BIOS software on CompatiCard IV to do its work. Somecomputers have so many
ROMS in them already that there is no address space for the BIOS on
CompatiCa rd I V. The NOROM software option solves this problem. When you
use NOROM, a temporary copy of the BIOS software is written to your program
memory each time you tum on the power to your computer. MEGAMATE.SYS
uses the memory resident copy of the BIOS to do its work. The ROM BIOS on the
card must be turned off (SW 1-1 ,2,3 all OFF).
The NOROM option is utilized when you add a line to your CONFIG.SYS file
causing the MM28BIOS.SYS device driver to be executed each time the computer
boots up. Perform the following steps to install the MM28BIOS.SYS device driver.
1) Using a suitable text editor or word processor, bring up the
CONFlG.SYS file from your DOS system disk for editing.
2) Substitute the J I card address setting (B-D) for the " x" in the line below.
Add the following line to the CONFlG.SYS file, making sure that it
precedes the line referencing MEGAMATE.SYS:
device=mm28bios.sys Ix
3) Save the modified CONFIG.SYS file on your DOS system disk. Make
sure the CONFlG.SYS, MEGAMATE.SYS,and MM28BIOS.SYS files
are all in the root directory so that DOS can find them when the computer
starts
up.
At this pointyourCONFlG.SYS file shouldcontain at least the following
two lines in the order shown:
device=mm28bios.sys
Ix
device=megamate.s ys
4) Restart the computer by pressing CTL-ALT-DEL.
