=================================== 
A. Setup and configuration 
=================================== 
 
A-1. Upgrading Corel CD Creator from Windows 3.1 to Windows 95
--------------------------------------------------------------
If you upgrade your system to Windows 95 after having previously 
installed Corel CD Creator, reinstall both CD Creator and the 
Corel CD-ROM device driver from within Windows 95. This will 
ensure that the software is properly configured for Windows 95.


A-2. Installing CD Creator on a dual boot system
------------------------------------------------
If you are configuring a dual boot system and intend to run CD 
Creator from both Windows 3.1 and Windows 95, you should install 
both CD Creator and the Corel CD-ROM device driver from within 
Windows 3.1, then reboot your system, start Windows 95 and reinstall 
both CD Creator and the CD-ROM device driver from within Windows 95. 
Although both installations can install the software to the same 
target directory, the dual installation is necessary to ensure that 
the software is properly configured to run under both versions of 
Windows.

The complexity of configuring a dual boot system increases if 
you are using two SCSI host adapters, since the two operating 
systems may initialize the SCSI host adapters in a different order. 
You can resolve this by installing the CD-ROM driver software into 
different target directories for the two operating systems. This 
will allow you to configure the 16 bit CD-ROM driver separately 
for each operating system.


=================================== 
B. Running on Windows 95 
=================================== 
 
B-1. Unknown device message when starting Windows 95
----------------------------------------------------
The first time Windows 95 starts after you attach a CD recorder 
to your system, the system may display a message stating that 
it has detected an unknown device. This message should be ignored. 
The drivers necessary to access supported CD recorders are installed 
with CD Creator.

B-2. Power on all devices before starting Windows 95
----------------------------------------------------
If you are not using a plug and play host adapter, it may not be 
possible for CD Creator to detect a SCSI device which was powered 
on or connected after Windows 95 started. Ensure that all devices 
are properly connected and powered on before starting Windows 95.


=================================== 
C. 16 bit CD-ROM device drivers 
=================================== 
 
C-1. Using 16 bit MS-DOS compatibility mode CD-ROM drivers
----------------------------------------------------------
Windows 95 provides a default set of 32 bit protected mode CD-ROM 
drivers. These drivers, however, do not support some of the more 
advanced features available on many of the current generation 
CD-ROM drives and CD recorders. The 16 bit MS-DOS compatibility mode 
CD-ROM device drivers (CUNI_ASP.SYS and CorelCDX), which are supplied
with CD Creator, can be used to make these advanced CD-ROM drive 
features available to CD Creator on Windows 95 when using supported 
SCSI CD-ROM drives. These advanced features include:

	- digital audio extraction
	- session selection
	- use of a CD Recorder as a CD-ROM drive

When installed while running under Windows 95, the CD-ROM driver 
setup program will make all of the necessary changes to allow these 
drivers to operate properly under Windows 95. If you upgrade your 
system to Windows 95 after having previously installed CD Creator, 
reinstall both CD Creator and the Corel CD-ROM device driver 
from within Windows 95. This will ensure that the software is properly 
configured for Windows 95.

Although Windows 95 was intended to fully support the use of 16 bit 
MS-DOS compatible device drivers, it is primarily designed to make 
use of 32 bit drivers. Because of this, there are certain caveats 
to be aware of when using the 16 bit MS-DOS compatibility mode 
device drivers supplied with CD Creator on a Windows 95 machine.

1) the overall performance of some CD-ROM drives may decrease 
   when using a 16 bit device driver. Depending on the drive, 
   the difference may vary from very little to quite significant.

2) loading 16 bit device drivers will decrease the amount of 
   conventional memory available to Windows. The CD-ROM driver 
   uses about 26K, while CorelCDX typically uses about 33K.

3) the Windows 95 autorun (or autoplay) feature is not operational 
   when using a 16 bit CD-ROM device driver. The setting of the
   devices 'auto insert notification' parameter has no effect.

4) when using a 16 bit CD-ROM driver with Explorer, attempting to 
   access a CD-ROM drive with no disc inserted will display an 
   empty directory listing rather than generating an error message.

5) an anomaly in the way the Windows 95 Explorer handles media
   changes for CD-ROM drives results in seemingly strange behavior
   after media or session changes. When a new disc is inserted, or
   the Corel Session Changer is used to select a new session on a
   CD-ROM drive, Explorer does not correctly register the media 
   change (or session change) when the drive letter icon is selected.
   You can, however, force the Explorer to resynchronize its display 
   with the actual contents of the disc by selecting Explorers View/
   Refresh menu option. This problem does not exist with the Windows 
   95 version of File Manager, nor when accessing the CD-ROM drive 
   from a DOS box. This behavior is not caused by the use of a 16 
   bit device driver, but is generally more apparent when a 16 bit 
   driver is in use due of the absence of auto insert notification
   (autorun) support. Similar behavior can be observed when using 
   the Windows 95 32 bit CD-ROM driver if auto insert notification 
   disabled.

6) the Performance page in System Properties (access via Start/
   Settings/Control Panel/System) will show that CD-ROM drives are 
   using MS-DOS compatibility mode file systems when 16 bit CD-ROM 
   drivers are being used.

7) due to the way in which Windows 95 implements support for 16 bit
   CD-ROM device drivers, it may not be possible to access some 
   non-SCSI CD-ROM drives when the Corel 16 bit CD-ROM driver is 
   installed. If you are using a non-SCSI CD-ROM drive, you may be 
   able to install the 16 bit MS-DOS compatible driver for your 
   drive. Alternately, Windows 95 may make the non-SCSI interface 
   card for your CD-ROM drive appear to the system as another SCSI 
   Host Adapter. In such cases, you may actually be able to use 
   Corel's 16 bit SCSI CD-ROM driver to control the non-SCSI 
   CD-ROM drive. To try this:

      - make a backup copy of the CRLSCSI.INI file which is in your 
        CD Creator directory.
      - run the Corel SCSI Config program.
      - select Corel CD-ROM Drivers, Included devices and then click
        the Edit, Add>>, and Scan buttons.
      - if the non-SCSI CD-ROM drive shows up in the resulting device
        list, highlight it and click the Select button.
      - select one of the Generic SCSI-2 compatibility options, and
        click the Install and Close buttons.
      - restart Windows 95.

   If you encounter problems accessing your non-SCSI CD-ROM drive,
   restore the original CRLSCI.INI file and restart Windows.
 
If, after installing the 16 bit drivers, you want to revert back to 
the use of the 32 bit Windows 95 CD-ROM drivers, you should:

	- rem out the 'device=CUNI_ASP.SYS' line in your CONFIG.SYS file
	- rem out the 'CorelCDX' line in your AUTOEXEC.BAT file
	- restart Windows 95
 

C-2. Configuring Corel's 16 bit CD-ROM driver for Windows 95
------------------------------------------------------------
When operating on DOS and Windows 3.1 platforms, Corel's 16 bit 
CD-ROM device driver communicates with SCSI devices via an ASPI 
manager. As the CD-ROM driver loads, it can scan the SCSI bus and 
automatically detect attached CD-ROM and CD Recorder devices. 
However, when running on a Windows 95 machine, the ASPI manager 
software is not loaded until after the CD-ROM driver. Consequently, 
you must use the supplied SCSI Config program to manually configure 
CD-ROM device driver. Please note that the CD-ROM driver Scan option 
within the SCSI Config utility detects only CD-ROM devices, and not 
CD recorder devices. If you need to scan the SCSI bus to locate the 
host adapter and device id of your CD recorder, you can use the 
SS.EXE utility from within a DOS box.


============================================ 
D. Known problems when running on Windows 95
============================================ 

1) on Windows 95 systems which use 2 or more different types of 
   host adapters, you may experience problems trying to access 
   the CD recorder from CD Creator. On such systems, if you can 
   not successfully run the CD Recorder System Test from within 
   CD Creator, please contact Corel Technical support as you may 
   require an updated driver.

2) if Windows 95 is installed on a hard disk other than drive C:, 
   the setup program will create CONFIG.SYS and AUTOEXEC.BAT files 
   on the Windows 95 disk rather than modifying the boot files on 
   C:\. This can be corrected by manually copying the changes over 
   to the proper boot files.
