two floppy disk drives. Any combination of
two 360K, 720K, 1.2M or 1.44M floppy diskdrives may be
connected. The JEI043 has been tested at expansion bus
speeds of up to 12MHz. The bus speed is often
independent of processor speed; consult your computer
owner's manual for information on bus speed.
• Operational
at expansion bus speeds up to 12MHz
• Fully compatible
with AMI and most other BIOS
• Compatible with 8088/8086,80286 and 80386 systems

Precautions yvhen working with any circuit board or IC, some
precautionsneedto beobserved for thesafestinstallation.
Many
parts arestaticsensitive and max be easily damaged
by static electricity that may have buIlt up in your body.
Thebest
way toassure thatno damage comesto your new
equipment IS to observe a few precautions: .
1. Whenever you move your body, you can easily build
up enough static electricity to damage a circuit board.
When handling a board or ICs, ground yourselfoften. The
best
way to do this is with a grounding wrist strap that is
properlyconnected to a ground. These
may be purchased
through Jameco Electronics; order part WS. Another wax
to ground yourself would be to plug the computer s
power supply into a grounded outlet (but leave it turned
off), then touch the frame of the power supply often to
dissipate
any static charge that you may have built up.
2. Make sure that the power supply is turned OFF before
installing
or removing anything. .
3. Hold all circuit boards and Ies by the edges.

Configuration
This section will cover the necessary hardware
configurations of the JEI043 and your computer.
Whenever possible, diagrams and tables have been
provided to clarify proper configuration. Default or
recommended settIngs will appear in italic type.
Since a
computer sy:stem must never have two floppy
controller
cards installed at the same time, you must make
sure that you remove (or disable) any existing floppy
controller card.
If
you have only one floppy disk drive installed in your
computer, 'DOS will consider it to be both logical drive A:
and lo~cal drive B:. if you have t':Vo floppy disk ~rives
installed in your computer, DOS wIll consIder the fIrst to
be logical drive A: and the second to be logical drive B:.
Refer to the glossary for a description of a logical drive
and a physical drive. .
All references to locations
on the JEI043 will be made as
if you were holding it in front of you, with the expansion
card edge to the bottom, and the mounting bracket to the
right. All pertinent jumpers and connectors are labeled
on the board. Please refer to the following diagram.

BIOS
Address
Jumper block JP1 allows you to select the address of the
ROM BIOS
that is on the JE1043. This jumper block is
located
at the lower left corner of the board. On most
computers, the factory default setting will not cause
conflicts.
However, as more and more expansion options
are developed, the possibili~ for two devices to be
addressed at the same location increases. To
accommodate this, the JE1043 can be addressed at either
of two memory addresses, in case conflicts arise. If you
experiencea conflict with another expansion board, such
as a hard disk controller card, try addressing the JE1043
at the alternate location. Set the address according to the
following table; defaults are in italics.

This jumper block allows you toenable or disabletheBIOS
on the JE1043. The BIOS provides the routines necessary
to
run the four floppy disk drive types supported by the
JEI043, without relying on whether or not the
motherboard is capable of supporting them.
If
your motherboard BIOS ROMisableto provide support
for all floppy disk drive types that you are using, you do
not need to enable the JEI043 BIOS ROM. It is only when

Installatio-n
This section will assist you in mounting your JEI043 and
preparing it for operation. Information is provided for
IBM and Jameco computers. If you have another type of
computer,
read thjs section and apply the information
contained here to
your application.
Open up ' your computer so you can access the
motherbOard. Pleasereferto thedocumentationthatcame
with your computer for information on how _to remove
the cover to access the motherboard.
On some computers there is a set of DIP switches or
jumpers that confi~re the motherboard for the number
and type of floppy disk drives installed in the system.
The
IBM PC has two switch blocks on the motherboard
labeled
SWl (near the center) and SW2 (near the power
supply). Each switch block has 8 DIP switches. Set the
switches 1, 7
and 8 ofSWI as follows:
Number of Drives

2 Off Off On
The IBM PC/XT and compatibles, have only one switch
block
on the motherboard that has eight DIP switches. It
islocated
near the power supply connectors. Setswitches

The IBM PCIAT (80286) and most AT comEatible
computers, including the Jameco Electronics JEl003,
JEloo7, JE3005, JE3010, JE3020, JE3025
and JE3030
motherboards,
do not require any DIP switch or jumper
changes that concern floppy disk drives configuration.
These
computers have a SETUP program that tells the
CMOS
parameters to recognize the types of floppy disk
drives connected. The CMOS parameters are usually
battery
backed-up so that the parameters are kept while
the
computer power is off.
There
may be some AT compatible computers that have
a DIP switch bank that needs to be configured when
installing the JEI043. Please consult the owner's manual
that came with your computer or contact your dealer for
information
regarding settingthemotherboardfor proper
floppy disk drIve/types.
At this
point your JEI043 should now haveall jumpersset
pro~rly and your motherboard should have its switches
set, if any.
If
you have an existing floppy controller card in your
system, you must remove (or disable) it. The computer
can only accept one floppy controller card. Remove the
existing cable
that had connected the original controller
card to
your floppy disk drives, if applicable.
If the above step
had not left an empty hole for the
mounting bracket on the JEI043, you should select a slot
9
that is convenient for routing cables to the floppy disk
drives and remove its ernpty bracket. Save the screw to
use later to secure the JEI043 in place.
Again
make certain that the computer's power is OFF.
SlIde theJEI043 into the selected slot. DONOT ROCK IT
FROM LEFT TO RIGHT OR DAMAGE TO YOUR SLOT
MAY RESULT. As
you slide it in, make certain that the
gold-plated connector fingers are correctly started in the
motherboard connector, tfien slowly and firmly press the
card into place. Check to see that the controller card is
fully
and properly seated in the connector.
Some
motherboards may be mounted too low in thecase,
causing
the metal bracket on the JEI043 to prevent you
from plugging it into the slot completely. This may be
corrected in one of the following ways: .
1. Ifthe motherboard is mounted withall metal standoffs,
it
may be possible to put insulated washers under each
one to raise the motherboard slightly.
2. Some cases allow for up and down adjustments of the
rear Fanel; simply loosen the its screws and adjust the
pane to a lower position. Tighten the screws only after
all expansion cards
have been installed and attached to
the rear panel.
3. The last possible method would be to bend or remove
the metal bracket of the JEI043. .
SecuretheJEI043
in place with thescrewpreviously used
to hold the empty bracket or old controner card. When
screwed in place, it should remain fully seated in the
motherboard connector.

Floppy Disk
Drive
Settings
Find the "drive select" jumper block or shunt located on
the floppy disk drive(s) you plan to use. Depending on
the manufacturer of your floPRY disk drive, the drive
select jumper blocks may be labeled many different ways
(e.g. 0 through 3, 1 through 4, A through D, DSO through
DS3, D1 through D4, and so on). Make sure each floppy
disk drive connected to the JE1043 is set to the.second
"driveselect". Forexample,if
you ha ve an FD55GFV drive
which has four "drive select" jumper blocks labeled DSO
through DS3, you would want to put a jumper acrossDS1.
Install
the floppy disk drive(s) you plan to use into the
computer if tney are not installed already. Be aware that
most floppy disk drives will not work if they are mounted
incorrectly. Forexample, the TEAC drives will not work
if they are mounted upside-down. If you are not sure how
this IS accomrlished, refer to your floppy disk drive
manufacturer s manual for recommended mounting
conditions. If this information is not included in your
manuals, consult your dealer.
Look
at the cable that came with the JE1043 and refer to
the figure below. You will notice a red or blue stripe on
one side of thecable. Thisstripesignifiesline one (1). You
will also notice
that between two of the connectors, the
cable has been split and "fliEped." Theconnector opposite
this "flip" connects to the JE1043. If the cable had come
connected to the JE1043 already, takea moment to ensure
that it is connected properly. If it is not connected to the
JE1043, connect it
now.
