drive icon is shown in this Window, everything should be functioning properly. If it
is not, then support for your SCSI controller did not load properly (Windows 95 can’t
look ‘‘through’’ your controller to see your drive). Select ‘‘Control Panel’’ and then
double-click the ‘‘Add New Hardware’’ icon and follow the instructions. This process
will take some time but hopefully will find the files necessary to support your SCSI
board. If it does not, it is possible that Windows 95 does not have the necessary file
available, or that non-SCAM capable support was loaded even though you purchased
a SCAM capable controller. You may need to contact the manufacturer of the SCSI
controller to get the correct file. It is also possible that your older controller simply
does not have support available for Windows 95 and will need to be replaced.
Plextor Provided SCSI Controller
•
If your Plextor-provided SCSI controller is
not
supported by Windows
95, you will be prompted to insert a disk that includes the appropriate
file. At this point you can insert the Plextor Manager disc, point
Windows 95 to the root directory, and it will automatically select and
install the proper file.
•
If your Plextor provided SCSI controller
is
supported by Windows 95,
it will automatically install non-SCAM capable 32-bit support for your
SCSI board. If your SCSI controller was not SCAM capable, this would
present no problem. However, since you purchased a SCAM capable
Plextor kit, you may experience problems. After the installation is
complete, copy the *. MPD file(s) from the Plextor disc to the correct
Windows 95 subdirectory using Windows Explorer or the following
DOS command:
copy A:*.MPD C:\windows\system\iosubsys
The non-SCAM capable file originally installed will be overwritten.
Disable Plextor Manager
Our preliminary tests indicate that Plextor’s device driver will operate your Plextor
drive under Windows 95. However, our device driver is written in 16-bit code and
has not been fully tested under Windows 95. In addition, all the utilities (and more)
available in 16-bit code Plextor Manager are also available in 32-bit code Plextor
Manager. Therefore, we recommend that you disable the driver. If you choose to
operate your Plextor drive under Windows 95 using the Plextor device driver and
subsequently encounter any problems, your first step should be to disable the driver.
To disable Plextor’s DOS/Windows driver, click on the ‘‘START’’ button. From the
pop-up menu select ‘‘RUN.’’ Type NOTEPAD C:\CONFIG.SYS. This allows you to
edit the CONFIG.SYS file using the notepad editor. Find the lines that refer to the ASPI
Manager (example: BTDOSM.SYS or ASPI4DOS.SYS) and device driver called
PLEXTOR.SYS. Type ‘‘REM’’ in front of each of those two lines. This disables these
