3) It is also possible that the SCSI controller you may have purchased
separately is not really SCAM capable. Not to worry, though. You
simply need to deal with SCSI ID selection. First, turn off your
computer. Review the 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.
4) It is possible that your previously or separately purchased SCAM
capable controller is not being supported properly by Windows
95/98. If you had to use the Windows 95/98 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 95/98 Add New Hardware Wizard to load it. If Windows
95/98 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 95/98 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 95/98 subdirectory using Windows Explorer or the
following DOS command:
COPY D:\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.
5) Finally, if you still suspect the CD-ROM drive as the source of the
problem, you should boot the system to DOS from a floppy. The
