solutions to the most common types of problems fielded by our technical support staff.
Our Technical Support Department will help you solve problems that relate specifi-
cally to your 12/20PleX drive. In many cases, a problem that appears to be caused by
your CD-ROM drive actually originates in another part of your computer. In such
instances, our technical support staff will try to help you identify the part (e.g., SCSI
interface board) at fault, and will refer you to the manufacturer of that part for further
assistance.
Although we think highly of the capabilities of our technical support staff, we
recognize that they do suffer from some limitations; namely, they do not possess
psychic or telepathic powers. Therefore, their ability to help you depends a great deal
on your ability to help them. You must act as their eyes and ears as they try to diagnose
and fix your problem. If you gather the information requested on the following page
before you contact them, you will find that your problem can be resolved much more
quickly.
Plextor’s Technical Support Department is available Monday through Friday, 6:30

Windows 95 Drivers
and Installation Guide
Quick Install
Windows 95 should automatically recognize and support your SCSI controller and
Plextor CD-ROM drive. Microsoft has included a generic CD-ROM device driver in
the operating system. They have also included numerous controller specific drivers
on the Windows 95 CD-ROM. If you connect your Plextor drive to a previously
installed and operating SCSI controller, Windows 95 will recognize the new controller
and ask you to insert the Windows 95 CD-ROM so it can obtain the necessary file. If
you purchased your SCSI controller in a Plextor kit, you can use either the Windows
95 CD or the Plextor Manager floppy disk to provide the necessary file. If you
purchased your new SCSI controller from another source, you must use the Windows
95 CD. If Windows 95 does not have the necessary file, you will need to use software
provided by the manufacturer of the SCSI controller. If you encounter any problems,
we suggest you read the following detailed instructions.
Detailed Instructions
If the Quick Install description above does not work, this section will tell you a little
about the Windows 95 operating system, help you figure out what your current system
configuration is, and then walk you through the installation. If you are lucky, this
process will be close to ‘‘Plug and Play’’. Either way, don’t worry. You will soon be
using the highest performance CD-ROM drive around. If you have any problems at
all, our technical support staff will help you out. They can be reached toll-free at
800-886-3935.
Microsoft has incorporated ‘‘Plug and Play’’ software into Windows 95. Theoretically,
this enables true Plug and Play peripherals, such as your Plextor CD-ROM drive, to
configure themselves automatically after installation. You have been hearing about
Plug and Play for a long time now from everyone and their brother. The reality: Anyone
telling you their product was Plug and Play prior to August 24, 1995 (the Windows
95 release date) was pulling your leg. The unfortunate thing is that even now things
are not quite as automatic as they should be. That’s all right though----Plextor will make
it work for you.
For a true Plug and Play experience while installing a SCSI peripheral many things are
required. Your system must have Plug and Play BIOS available either on the motherboard or on a Peripheral Component Interconnect (PCI) SCSI controller. All PCI
controllers have this capability. Your controller itself must also have its own Plug and
64 12/20PLEX OPERATION MANUAL
Page 7
Appendix ---- Windows 95 Drivers
Play capabilities. Again all PCI controllers include these features. Your SCSI controller
must also be SCAM capable. It may sound like a con game, but actually SCAM stands
for SCSI Configured Auto Magically (sure it sounds hokey, but we didn’t make it up).
Others may refer to it as SCSI Configured AutoMatically.
Any combination of up to seven internal and external devices can be attached to a
single SCSI controller. Each must be set to a unique ID number (0--6) for identification
purposes in your computer system. SCAM is the Plug and Play feature that overrides
whatever a device’s SCSI ID is set to (physically, via jumpers or switches on the back
of the drive) and makes sure each device has a unique ID.
The problem is that even with all the delays in releasing Windows 95, most peripheral
manufacturers were not fully prepared to implement SCAM. As a result, this was
removed from the final list of requirements for obtaining the ‘‘Designed for Microsoft
Windows® 95’’ certification.
Your computer’s capabilities are pretty much out of our control. On the other hand,
your Plextor drive is fully SCAM capable. Benevolent folks that we are, if you bought
a Plextor ‘‘kit’’ you also have a SCAM capable SCSI controller in front of you----wouldn’t
make much sense to sell you a true Plug and Play drive and some old technology
controller board, would it? You can also buy SCAM capable controller kits off the
shelf at most computer stores by now. It is possible that you have a PCI SCSI controller,
which means you are in really good shape, especially if you have already installed
Windows 95. We also include a floppy disk that gives you some great utilities and
makes this whole Plug and Play thing work (more on that coming up).
To the best of our knowledge, Plextor’s 4PleX Plus was the first ever SCAM capable
CD-ROM drive----another first for Plextor. Of course, as we revise this in 1997, those
other guys are still pulling your leg. Just because they say Plug and Play it doesn’t
mean it’s true. And all those Windows 95 logos you see do not really promise Plug
and Play; they only promise functionality once you finally get the device installed and
configured properly.
So, let’s say your computer is Plug and Play or you have a PCI SCSI controller, your
SCSI controller and Plextor CD-ROM drive are SCAM capable, and you have
successfully installed Windows 95. No problem, right?
Wrong. In Windows 95
various files are used to support different SCSI controllers (think of them as device
drivers). Unfortunately, different files are used in a SCAM environment than are used
in a non-SCAM environment. To make matters worse, some Windows 95 releases
will not recognize when your controller is SCAM capable and load the correct file.
Instead, since SCAM was not a requirement for logo certification by the time Windows
95 was released, and most devices were not yet capable, it automatically loads the
files that support the non-SCAM device.
As you might suspect by now, Plextor fixes this problem for you. Just pay close
attention to the instructions and everything will work out fine. Now that we have bored
you with the history and current state of Plug and Play, it’s time to get that great new
CD-ROM drive up and running. Turn the page and let’s get you started.

Configuration Identification
The first thing you want to do is figure out exactly what your configuration is and what
you are trying to accomplish. Review the following descriptions and then go to the
appropriate section of this manual.
• You have purchased a new SCAM capable Plextor CD-ROM drive kit
with a SCAM capable SCSI controller. If you purchased just the drive
without a SCSI controller, it is also possible (though unlikely) that you
already had, or separately purchased, a SCAM capable SCSI controller
board. Your computer has a Plug and Play BIOS or your SCSI
controller is of the PCI variety. You have Windows 95 installed. You
may have purchased a new computer with Windows 95 installed, or
you purchased an upgrade to Windows 95 on floppies and already
installed it. You may also have upgraded to Windows 95 from a CD
using an older CD-ROM drive. If this scenario describes your situation, consider yourself a state-of-the-art computer jockey. Go to the
section titled ‘‘Plug and Play Installation,’’ page 67.
• You have a SCAM capable controller as in the Plug and Play configuration, but your computer is a little older and does not have a Plug
and Play BIOS. You also do not have a PCI class SCSI controller to
provide Plug and Play BIOS. Go to the section titled ‘‘Non-Plug and
Play Installation,’’ page 70.
• You did not buy a Plextor kit and have an older SCSI board that is not
SCAM capable. Go to the section titled ‘‘Non-SCAM Installation,’’
page 72.
• You are currently running DOS or Windows 3.x and have purchased
an upgrade to Windows 95 on CD-ROM. Since you do not have an
old CD-ROM drive, you need to install your new Plextor CD-ROM
drive first. But you need to run the upgrade while in a DOS/Windows
environment, and you need a device driver. Problem? Not with
Plextor. We provide all the software you need to run under DOS/Windows and upgrade to Windows 95. It’s a bit complex, but we’ll get
you there. Go to the section titled ‘‘Upgrading to Windows 95 From
DOS/Windows Using CD-ROM,’’ page 74.
By the way, our instructions generally assume you are installing a SCSI controller as well
as a Plextor CD-ROM drive. Of course, it is quite possible you already have a SCSI
controller installed and operating under Windows 95. If so, you can make appropriate
adjustments to the procedures. For instance, since your controller is already functioning
under Windows 95, it will not ask for a disk or CD to get support for the controller. We
have addressed some potential problems this may cause in the troubleshooting portion
of each section.

Appendix ---- Windows 95 Drivers
Plug and Play Installation
Install Hardware
You should be able to simply install your SCSI controller, CD-ROM drive, and all
cabling without any concern for things like SCSI ID selection. First, turn off your
computer system, then review the Hardware Installation chapter of your drive’s
Operation Manual for installation instructions. You should also familiarize yourself
with the chapter on Termination. However, the quick solution here is to place your
internal drive at one end of the SCSI ribbon cable and the SCSI controller at the other
end of the cable. Your drive ships from the factory with termination enabled so
everything should be fine. If you put another SCSI device between the controller and
the drive, you need to make sure termination is disabled on that device. For external
devices, if your Plextor drive is the last in a chain of devices, leave termination
enabled. If it is not last in the chain, disable termination. All SCAM capable boards
should have the ability to automatically set termination of the board itself so you
should not have to deal with this. Once your hardware is Plugged in, it is time to Play.
But of course we first have to take care of that little device driver problem.
Install Software
After your CD-ROM drive and SCSI controller are installed, it is time to make the right
software file available to complete your Plug and Play environment. Turn on your
computer, and your system should automatically detect and configure your SCSI
controller. When you start Windows 95 it will then recognize that it does not have the
right driver available for your new SCSI controller. A dialog box named ‘‘New Hardware
Found’’ appears, followed immediately by a dialog box named ‘‘Insert Disk.’’ At this
point, click on ‘‘OK’’ in the ‘‘Insert Disk’’ dialog box and a second ‘‘New Hardware
Found’’ dialog box will appear. It will ask you to insert the Windows 95 disk or CD.
Please, DON’T DO IT. If you do put in your Microsoft disk or CD, Windows 95 may
automatically load the non-SCAM capable file for the SCSI controller we provided.
Instead, if you purchased a Plextor kit with SCSI controller, insert the Plextor Manager
disk. This disk has the SCAM capable support file for your SCSI controller to complete
your Plug and Play CD-ROM environment. After inserting the disk, select ‘‘Browse’’
in the dialog box and then select the appropriate drive letter (probably A:\). The
Windows 95 configuration process should select the correct file off the floppy disk
and copy it to the correct Windows 95 subdirectory on your hard drive.
If you purchased a SCAM capable SCSI controller separately, the correct file is
hopefully located on a disk provided with the controller. We suggest you first try using
this disk, supplied by the manufacturer of your SCSI controller, rather than inserting
the Windows 95 disk. If you do not have such a disk (or cannot find it among all the
12/20PLEX OPERATION MANUAL
67
Page 10
Appendix ---- Windows 95 Drivers
other disks you have), you can try using the files provided by Windows 95, but we
cannot guarantee you will get SCAM support.
Reboot Your Computer
Reboot your machine by selecting ‘‘SHUT DOWN’’ from the START Button. In the
shut down dialog box select ‘‘Restart the Computer’’ and select ‘‘YES.’’ This will reboot
your computer with the new configuration. As your system goes through all its self
checks, you might find it interesting to watch the display and note the SCSI ID that
has been assigned to your CD-ROM drive. Your drive came from the factory physically
set to ID #3. It is possible (especially if you have other SCSI devices) that once you
reboot your computer, the configuration process will reassign the drive to some other
SCSI ID number. If so, you have just seen visual proof of Plextor’s SCAM capabilities.
Get out your favorite or most useful CD and enjoy.
Troubleshooting
If you followed the previous instructions, you should be up and running without any
problems. If things are not working correctly, there are four likely problems.
• First, you might have overlooked our instructions to use the Plextor
Manager disk to get the necessary driver support for your SCSI
controller. If you used the Windows 95 disk or CD, the configuration
process may have copied the wrong (i.e., non-SCAM capable) driver
support. Then, if some other SCSI device attached to your SCSI
controller is physically set to the same ID as your CD-ROM drive, a
conflict will occur. To solve this problem, insert the Plextor Manager
disk or use Windows Explorer or the following DOS command to copy
the correct file to the applicable Windows 95 subdirectory:
copy A:\*.MPD C:\windows\system\iosubsys
Reboot again and everything should work fine.
• The second likely cause is that your motherboard may not have a Plug
and Play capable BIOS and your Plug and Play SCSI controller is not
of the PCI variety. You will need to turn off your computer and disable
the Plug and Play capabilities on your SCSI controller. Review the
controller’s documentation (check the Quick Start Guide or similar
document first) to determine the location of the disable switch. After
disabling, review the ‘‘Install Hardware’’ portion of the Non-Plug and
Play Installation section of this manual. Make sure termination is set
properly on your controller and all devices attached to it. Restart your
computer.
68 12/20PLEX OPERATION MANUAL
Page 11
Appendix ---- Windows 95 Drivers
• It is also possible that the SCSI controller you may have purchased
separately is not really SCAM capable as you thought. Not to worry,
though. You simply need to deal with SCSI ID selection. First, turn off
your computer. Review the Operation Manual discussion of SCSI ID
selection (Chapter 6) and then check the physical selection of SCSI
ID on your CD-ROM drive and any other SCSI devices connected to
your controller. Make sure that all devices are physically set to unique
IDs. Since your board is not SCAM capable, it will probably not have
automatic termination. You will also need to make sure the termination of your board is set properly. If you have both internal and
external devices attached, the termination on your controller should
be disabled. Review the controller’s documentation to determine how
to do this. If you have ONLY internal devices, or ONLY external
devices, termination of your SCSI controller should remain enabled.
After your IDs and termination are set properly, restart your system.
• Finally, it is possible that your previously or separately purchased
SCAM capable controller is not being supported properly by Windows 95. If you had to use the Windows 95 disk or CD to get support
for the controller, it may not have existed, or it may have loaded a
non-SCAM capable version of the file. If the file did not exist, you will
have to contact the SCSI controller manufacturer to obtain the necessary file (you might first look through your own stack of disks one
more time). Once you have the correct file, you can then use the
Windows 95 ‘‘Add New Hardware Wizard’’ to load it. If Windows 95
did load a file during the configuration process, AND you have
another SCSI device besides your Plextor CD-ROM drive, then you
probably have a conflict with your SCSI IDs. In other words, Windows
95 loaded a non-SCAM capable support file. The quick fix here is to
leap out of the Plug and Play environment and reset the SCSI ID on
one of your devices per the previous paragraph. Alternatively, you
can find or obtain the SCAM capable file from the manufacturer of
your SCSI controller. You will then need to copy that file to a Windows
95 subdirectory using Windows Explorer or the following DOS
command:
copy A:\filename.ext C:\windows\system\iosubsys
The SCSI controller documentation should tell you which file to copy.
If not, you should contact the technical support department of the
SCSI controller manufacturer. If you cannot reach them, or they cannot
help you, contact Plextor’s Technical Support Department.

Non-Plug and Play Installation
Install Hardware
Refer to the Operation Manual for instructions on installing your SCSI controller,
cabling, and CD-ROM drive. If your non-PCI controller has Plug and Play features but
your computer system is not supporting Plug and Play, you will need to disable the
Plug and Play capabilities on your SCSI controller. Review the controller’s documentation (check the Quick Start Guide or similar document first) to determine the location
of the disable switch.
You might want to familiarize yourself with the chapter on Termination in your drive’s

computer and start up Windows 95, and your system should automatically detect and
configure your SCSI controller. If you have just installed it, Windows 95 will then
recognize that it does not have the right driver available. A dialog box named ‘‘New
Hardware Found’’ appears, followed immediately by a dialog box named ‘‘Insert
Disk.’’ At this point, click on ‘‘OK’’ in the ‘‘Insert Disk’’ dialog box and a second ‘‘New
Hardware Found’’ dialog box will appear. It will ask you to insert the Windows 95
disk or CD. Please, DON’T DO IT. If you do put in your Microsoft disk or CD, Windows
95 will automatically load the non-SCAM capable file for the SCSI controller we
