ULTRAPLEX 40X OPERATION MANUAL
Troubleshooting
If you followed the previous instructions, you should be up and running without
any problems. If things are not working correctly, there are three likely problems:
1) You might have inadvertently copied the SCSI controller support files
on the Plextor Manager disk into your Windows subdirectory. It is
possible the SCAM files on our disk are not properly supporting your
controller. To solve this problem, delete the applicable *.MPD file(s)
from C:\Windows\System\Iosubsys and then reinstall the correct
support file using the Windows 95/98 Add New Hardware Wizard.
(See Add New Hardware, page 83, in the Upgrading to Windows
95/98 from DOS/Windows Using CD-ROM” section.) Restart your
system and everything should work fine.
2) The second likely cause is that your previously purchased SCSI
controller supports some Plug and Play features, but it is not PCI and
is not SCAM capable, and you also have no Plug and Play BIOS on
your motherboard. You will need to disable Plug and Play on your
controller. Turn off your computer. Review the controller’s
documentation (check the Quick Start Guide or similar document
first) to determine the location of the disable switch. Double-check for
proper termination. Restart your computer.
3) Finally, you may have failed to set a unique SCSI ID for each of your
peripheral devices connected to your controller. Turn off your
computer. Review SCSI ID selection (Chapter 6) and then check the
physical selection of SCSI IDs 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. After your IDs are set properly, restart
your system.

Install Hardware
If you are installing your Plextor drive in a Plug and Play environment (Plug
and Play BIOS on the motherboard and a SCAM capable controller), refer to
Install Hardware of the Plug and Play Installation section on page 72.
If you are installing your Plextor drive in a non-Plug and Play environment (no
Plug and Play BIOS on the motherboard, and your interface card is not PCI but
is SCAM capable), refer to the Install Hardware portion of the Non-Plug and
Play Installation section on page 76.
