1.  CD-ROM Drive Support
=-=-=-=-=-=-=-=-=-=-=-=-=

Adaptec's CD-ROM driver, ASPICD.SYS, has been written to fully support
any SCSI-2 CD-ROM drive.

The following drives have been tested by Adaptec with Adaptec 
EZ-SCSI 3.1.  All drives support both audio and data.  Photo CD is
supported where indicated:

*    These drives do not directly support Photo CD.  However, by adding
     /XAEMUL to the ASPICD.SYS command line, in your CONFIG.SYS, we will
     emulate support for single-session Photo CD on these drives.

**   These drives do not support parity.  Please consult the troubleshooting 
     section of the users manual for information on using these drives.

***  These jukebox CD-ROM drives are fully supported.  A drive letter will
     be assigned for each CD.

2.  Troubleshooting/Limitations
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

o  SMARTDRV 5.0 (in MS-DOS 6.2, Windows for Workgroups 3.11) now includes
   caching for CD-ROM drives.  There is a problem with SMARTDRV in its
   support for XA formatted Compact Discs.  If you experience "Not Ready"
   errors, using SMARTDRV 5.0, add /E:2048 to your SMARTDRV command line.
   For example:

   C:\DOS\SMARTDRV /X /E:2048

o  EZ-SCSI for Windows (SETUP.EXE) will not load its 3-D look DLL (CTL3D.DLL)
   if you are using Central Point PC Tools for Windows Desktop.  The
   installation will still proceed without any loss of functionality.

o  You should install Adaptec EZ-SCSI to a drive letter that exists at boot
   time.  This would NOT include RAM drives, network drives, removable
   drives, etc.

o  We have seen at least one case where an unstable video driver would
   cause EZ-SCSI for Windows to hang during installation.  If you are
   experiencing similar problems, try using the standard VGA driver that
   comes with Windows.  If EZ-SCSI for Windows then installs properly,
   you may want to contact your video card company for updated drivers.

o  In the unlikely event that you encounter a timeout failure when EZ-SCSI
   for Windows scans the SCSI bus, you should run EZ-SCSI for DOS first.
   Let it modify your CONFIG.SYS to load the appropriate ASPI managers;
   reboot your system.  You should then be able to run EZ-SCSI for Windows.

o  If you have an IBM ThinkPad 360Cs or an IBM ThinkPad 755, and are using 
   the Adaptec APA-1460 SlimSCSI, you need to move the following line to 
   the last line inside your CONFIG.SYS file:

         DEVICE=C:\EZPLY\$ICPMDOS.SYS

   Note: If the directory for EZ-Play is different than the default, use
   that directory instead. The above line uses the standard directory as
   an example.
