  ------------------------------------------

  If you're upgrading from CorelSCSI for DOS or Windows 
  version 1.2 or earlier, you must remove any system patches 
  before installing CorelSCSI 2. You remove patches using  
  the CorelSCSI software.

  To remove a patch
  1. At the command prompt, type PATCH.
  2. Select the Remove Patch option.


  Installing ASPI Managers

   UltraStor Ultra 24FA            1.04              USPI24.SYS


   If you have problems with the ASPI manager, contact the manufacturer
   of your card.
   
   If the ASPI manager for your card isn't included with the 
   installation, you must install your card's ASPI manager and
   load it in your CONFIG.SYS file before installing CorelSCSI.

   To load an ASPI manager in your CONFIG.SYS file

   1. Copy the ASPI manager from the diskette provided with your 
      SCSI card to your hard drive.

   2. Add the device driver line to the CONFIG.SYS file using
      the following syntax:

	 DEVICE=C:\xxxx.SYS

      where xxxx indicates the name of your ASPI manager.

   3. Reboot the system before you start the CorelSCSI installation.
      While the system is rebooting, you should look for status 
      messages from the ASPI manager. If the status indicates 
      unsuccessful installation, the CorelSCSI device driver won't 
      function.


   About Future Domain Host Adapters
   ---------------------------------

   If you're using an 8-bit host adapter with the BIOS version 8.2    
   or a 16-bit host adapter with the BIOS version 3.2, DCAMxxx.EXE
   is optional. However, if you're also using the QEMM memory 
   manager, you must use both DCAMxxx.EXE and ASPIFCAM.SYS.

   TMC-950 HOST ADAPTER:
   DCAM950 can support multiple adapters. The TMC-950 adapter 
   requires that you specify the memory location of the adapter and 
   the IRQ setting of the adapter using the following command line 
   syntax:
							       
     DEVICE=DCAM950.EXE /MEM IRQ [/MEM IRQ [/MEM IRQ]]           
							       
   The default setting for a single adapter looks like this:
							       
     DEVICE=DCAM950.EXE /CA00 5                                  

   Valid memory locations for the TMC-950 are CA00, C800, CE00 and DE00.

   Valid IRQ's are 3, 4, 5, 10, 11, 12, 14, and 15.


   TMC-18XX HOST ADAPTER:
   The TMC-18XX host adapter doesn't require any command 
   line settings:                      
							       
      DEVICE=DCAM1800.EXE                                         


   About DPT ASPI Managers
   -----------------------

   The DPT ASPI managers provided have been renamed because of 
   duplicate names. However the installation will rename the 
   selected ASPI manager to DPTDDL.SYS.
							       
   - DPT ASPI for SCSI BIOS ROM\SMARTROM V.001.K   DPTDDL1K.SYS
   - DPT ASPI for SCSI BIOS ROM\SMARTROM V.002.B   DPTDDL2B.SYS


    Using Memory Managers
    ---------------------

    If you're using a memory manager, you may need to uninstall it
    before installing CorelSCSI, and then reinstall the memory 
    manager. In rare cases, systems may hang if CorelSCSI is 
    installed while a memory manager is loaded.


ABOUT CORELSCSI 2 UTILITIES
===========================

   CD-AUDIO and CDDA: Digital Audio Sampling
   -----------------------------------------

   The following drive models support digital audio sampling, which 
   is used with CDDA (for DOS users) and CD-Audio (for Windows
   users):

   * Toshiba XM3401
   * Sony CDV561 (and OEM versions such as Compaq CDV561)
   * Apple CD300


   CorelCDX
   ---------
   
   DRIVER NAMES:
   If CorelCDX can't find driver names in the CRLSCSI.INI file, 
   try to locate and initialize drivers named 'MSCD001' and 'MSCD099'.
   These are the default names which the CUNI driver will use. 
   If the CRLSCSI.INI file is missing, CorelCDX should
   be able to use the default names used by Corel CUNI device 
   driver(s). This default action should NOT be done if ANY device 
   driver names are given for CorelCDX in the .INI file.

   For information about the CRLSCSI.INI options for the CorelCDX XMS 
   caching program, see "CDXCACHE.BIN" in this file.

   You can configure CorelCDX not to terminate directory searches 
   early. Add the option 'SlowSearch=YES' in the [CorelCDX] section 
   of CRLSCSI.INI. With this option enabled, CorelCDX will find 
   files even though the directory file is not correctly sorted. 

   Note that by enabling this option, the overall system performance
   may be affected. This option is NOT supported by either DOS or
   Windows Configuration programs. You must enter the option 
   manually. 


   VERSION 5.0 OF MICROSOFT'S SMARTDRIVE DISK CACHE UTILITY:
   Version 5.0 of Microsoft's SmartDrive disk cache utility, 
   provided with MS-DOS 6.2, is capable of caching CD-ROM drives. 
   The program is designed to work exclusively with MSCDEX CD-ROM 
   driver. However, Corel's PATCH_SD.COM program can modify the 
   SMARTDRV.EXE to recognize CORELCDX as a valid CD-ROM driver 
   and cache CD data.

   The SMARTDRV cache uses memory more efficiently than Corel 
   CDXCACHE; the same block of memory will be used simultaneously 
   for hard disk and CD disk caches. On the other hand, the CDXCACHE 
   program has smaller overhead and operates faster then SMARTDRV. 
   Note that the CORELCDX /UNLOAD option will not work with
   SmartDrive, as the cache program needs to be loaded after 
   CorelCDX.

   PATCH_SD.COM is designed to modify version 5.0 of SMARTDRV.EXE 
   (45145 bytes in size only). If the binary image does not match, 
   the patch will not be installed. The patching program scans 
   memory to locate the active SmartDrive cache program and from 
   there, locates the original disk image of SMARTDRV.EXE. If 
   the SmartDrive cache is not currently installed, the program 
   prompts you to enter the full path and name of the disk file 
   to patch.

   The original Microsoft SMARTDRV.EXE is saved in the same 
   directory as SMARTDRV.MSC.

   For the patch to work, you need to reboot the system to 
   reinstall SMARTDRV.EXE. For SmartDrive to recognize a CD 
   device, the CorelCDX driver needs to be installed before 
   SMARTDRV.EXE. Therefore, you must change the sequence of 
   entries in AUTOEXEC.BAT.


   EXTENDED MEMORY CACHING USING CDXCACHE.BIN:
   CDXCACHE.BIN is an extended memory cache. For information about 
   using CDXCACHE.BIN, see the online help provided with the 
   Configuration utility.

   If you're using DOS 5.0, Norton Shell 6.0, and the extended
   memory cache, Windows won't run. Remove or upgrade any one 
   of the three programs to resolve this problem.

   The CRLSCSI.INI file includes the following CDXCACHE options: 

   *  XMSSIZE indicates the cache size in kilobytes. You can set 
      XMSSIZE to  
    
      0 to disable the XMS cache. Note that the number of tracks 
      created on a CD by CDCOPY is affected by the amount of a
      vailable XMS memory, you should disable the extended XMS 
      cache when using 
      CDCOPY.

      -1 to use a default cache size, which is equal to one-quarter 
      of the free XMS memory.
  
      a specific size from 64K to 16384K.

   *  XMSPAGE configures the number of sectors per cache page, which 
      determines the read-ahead operations. The value of 4 is 
      recommended for smaller cache sizes; it's more important to 
      cache separate disk reads than to perform read aheads. Use 
      the value 8 for larger cache sizes; more data is stored 
      in one operation. The default setting is 4 sectors per 
      cache page.

   *  XMSBLOCK represents the maximum size of read request in sectors 
      that will be cached. The cache performance may benefit from 
      larger values. However, the cache may fill up more quickly. 
      The default setting is 4 sectors.

   CDSESN:
   If you run CDSESN, CD-ROM caching software (including 
   CorelCDX/CDXCACHE) will flush any cached data for the specified 
   drive even if the currently selected session is not changed.

   TOOLS (DOS and Windows)
   -----------------------
   
   If you're using an IBM host adapter and its ASPI manager,
   the information displayed by the Device Information
   command is incorrect. 
   
   When formatting a hard disk that has previously been formatted
   with multiple partitions, you should reboot when the format
   is complete. MS-DOS will let you access the original logical
   partitions even though they no longer exist.

   We've detected spurious errors while running diagnostics on
   various optical drives. These errors should not be thought
   of as hardware or media failures unless they occur repeatedly
   while diagnostics is looping continuously.

   DOSTools reports a fixed disk as containing removable media.

   With MS-DOS version 6.0, DOSTools will hang when you try
   to format any media. This problem doesn't occur in 
   MS-DOS version 6.2. The MS-DOS upgrade is available electronically, 
   without charge, or from retailers for a nominal fee.
   Windows Tools will function correctly.  


   CDSESN
   -------
   
   If you run CDSESN, CD-ROM caching software 
   (including CorelCDX/CDXCACHE) will flush any cached data 
   for the specified drive even if the currently selected session 
   is not changed.


   BACKUP 
   ------
 
   The Catalog Files Path option in Preferences defines where 
   catalog files created by the Backup utility are stored. 
   If you change this location, you must restart the application
   before the changed setting takes effect.

   Backup can read tapes written with SY-TOS.  If you 
   want to restore tapes written with SY-TOS, you must add 
   information to the [CorelSCSI Backup] section of your 
   CRLSCSI.INI file. This file is located in the CorelSCSI 
   installation directory.

   To restore SY-TOS tapes, add the following line:

     bSyTOS=1

   If the tapes were written with a version of SY-TOS later 
   than version 1.32, you must also add the following:

     bSyTOS_132=0

   NOTE: You must remove these lines from the CRLSCSI.INI
   file if you want to restore tapes written with the Corel
   backup utilities CTBACKUP or WTBACKUP.

   When you format tapes using Backup, you have the
   option of using error correction code. Only QIC tape drives 
   support error correction code. If you aren't using a QIC tape
   drive, make sure that you don't mark the Error Correction Code
   selection box.

   There is a problem with updating the progress bar during small 
   tape backups.  The application will show the tape rewinding 
   before the progress bar gets to 100%.  This is a graphics update 
   problem.  All requested data was written to the tape.  If you 
   wish to verify this, enable a log file ("Preferences" from the 
   File menu), and perform a full verify of the backup.  The log 
   file will confirm that all files were properly backed-up.
 
   A problem has been reported with file tagging when you have 
   a directory structure as follows:

   dir1
   |
   +---dir_with_files_1
   |
   |
   +--empty_dir_1
      |
      +---empty_dir_2
	   |
	   +---dir_with_files_2


   If you untag "dir1", then tag some files in "dir_with_files_1", 
   then tag "empty_dir_1", then untag "dir_with_files_2", the 
   application should show the checkbox of "dir1" as gray 
   (meaning that some files will be backed-up).  Instead, the 
   checkbox will show that no files will be backed-up, even though 
   the checkbox for "dir_with_files_1" indicates that some of its 
   files will be backed-up.  
   
   WARNING: If you proceed with this backup, none of the files 
   in "dir_with_files_1" will be backed-up!  The solution is to 
   tag the files and directories in a different order.

   CD-Audio 2
   ----------

   CD-Audio 2 for Windows is designed to work with a large variety 
   of True Type fonts. However, fonts with very wide characters as 
   well as other fonts won't display 
 

   CD-Audio 2.0 supports Microsoft's Music Box 2.0. Any track 
   information you've entered using MusicBox is imported into 
   CD-Audio.
  
   If you're using an LMSI CM234 CD-ROM drive, the status information 
   may not display the correct information. This is a problem with the 
   drive rather than CD-Audio.


   CorelTWAIN Device Driver
   ------------------------

   CorelSCSI 2 for Windows provides a device driver for scanning 
   images into TWAIN-compliant graphics applications. This section
   provides information about how to improve the scanning speed of 
   this device driver and how to use supplemental device drivers.

   You can improve the scanning speed of the Corel TWAIN device
   driver by pre-allocating memory.

   The program GRABMEM.EXE located in the WINDOWS\TWAIN\CORTWAIN 
   directory pre-allocates up to a 32K block of memory.

   The program must be run before starting Windows. To run the 
   program, you can place the following line in your AUTOEXEC.BAT:

      c:\windows\twain\cortwain\grabmem.exe
   
   Grabmem.exe can be removed from memory by running grabmem from
   outside windows with the /U switch:

      c:\windows\twain\cortwain\grabmem /U
   
   Epson and Microtek with Adaptec SCSI controllers:
   Your computer may hang during scanning if the Corel ASPI
   driver is used. Add the following switch to the APSIDRV.SYS
   command in your CONFIG.SYS file to fix the problem:
      
       DEVICE=ASPIDRV.SYS /Dhan,id,1     
       
   where han represents the host adapter number, id represents the 
   SCSI ID of the scanner, and 1 is a mandatory option.

   Ricoh scanners and Adaptec SCSI controllers:
   The Ricoh IS50, IS60, and IS410 will cause your machine to lock
   up during power-up if:  
      (a) the scanner is turned on before you turn on your computer
      (b) you are using some Adaptec controllers such as the 
	  1542B and 1542C.

   The solution is to power up your Ricoh scanner AFTER you power
   up your computer.

   CTSAMPLE application:
   With some video drivers, the scanned image will not appear in
   the scan windows after a scan in one of the 'Fit-In-Window' or
   'Display-1-to-1' modes.  The scanned image will often be visible
   if a different viewing mode in the VIEW menu is selected.
  
   Scanning using an Automatic Document feeder:
   If your scanner supports this feature, the multiple scans will not 
   all appear on screen in the Corel Twain Sample Application, but 
   rather only the last scanned item will appear. The other scans are 
   stored in your root directory and will be labeled CORELX.BMP where
   X= the number of the scanned item. You may view the other scans by
   selecting FILE then the OPEN FILE option from the Corel Twain Sample
   Application.

   Using Supplemental Device Drivers:
   Using supplemental device drivers, some other manufacturers' 
   scanners can be supported. These device drivers are located in the 
   WINDOWS\TWAIN\CORTWAIN\OEMTWAIN directory.

   The supplemental device driver takes the form of an MS-DOS device 
   driver, often used in conjunction with the manufacturer's own 
   device driver. Only one of these other scanners may be used at 
   a time.

   Scanner         Associated Files
   -------         ------------------------------------------------
   EPSON 300C      EPSON.DOC describes the setup procedure.
		   EPSON.SYS is the required MS-DOS device driver.

   MICROTEK 600Z   MICROTEK.EXE file is the required MS-DOS 
		   device driver.
  
   MICROTEK        MICROTEK.DOC describes the setup procedure if 
		   you're using MSCAN.SYS.

   Corel ArtView Screen Saver
   --------------------------
   
   If you select the sound option on systems with lower memory 
   configurations, you may experience long delays before an image 
   is displayed or intermittent sound output.


   DOSAUDIO
   --------

   If you're using an LMSI CM234 CD-ROM drive, the status information 
   may not display the correct information. This is a problem with 
   the drive rather than DOSAUDIO.


   CDCOPY
   ------

   The number of tracks created on a CD by CDCOPY is affected by the 
   amount of available XMS memory. If you're using CDXCACHE, you 
   should use the Configuration utility to set the XMSSIZE option, 
   which indicates the cache size in kilobytes, to 0.

   Some 'multi-session' CD-ROM drives currently only recognize a 
   disc as being multi-session if it's recorded in XA format such 
   as a multi-session PhotoCD. As CDCOPY writes Mode 1 data (not XA 
   format), these drives mistakenly interpret the disc as single 
   session. Drives that are known to be able to recognize multi-
   session Mode 1 data discs include the Chinon CDS535, Sony CDU561,
   and Toshiba XM3401. Contact the manufacturer of your drive to 
   verify its ability to read multi-session, non-XA discs.

   After recording multiple sessions of data on some brands of 74 
   minute CDR discs, the Philips CDD521 CD Recorder may experience 
   problems trying to reload the disc at a later date. If you 
   experience this problem, you may need to contact Philips 
   Consumer Electronics Technical Support at 1-800-835-3506 for a 
   possible firmware upgrade You can also try 

      (1) using 63 minutes CDR discs
      (2) using a different brand of 74 minute CDR discs
      (3) using CDCOPY with /lw switch, which writes data 
	  as the 'final' session on the disc. The disc is then 
	  non-writable.

   The target directory specifications should not include references 
   to either the "." or ".." subdirectories (this directory or parent 
   directory). Doing so will result in the creation of invalid 
   subdirectories.


   CorelBook
   ---------

   Some systems running ATI Mach 32 video driver version 2.0 may 
   experience problems loading CorelBook.

   Some systems running Standard mode Windows may experience 
   problems closing CorelBook when CD-ROM media browser is loaded. 

   With IBM PC-DOS 6.1, the Operating System Summary page reports
   the actual DOS version as DOS version 6.0. This is correct, as
   this version of DOS reports itself as 6.0.

   When unloading the CD-ROM Media Browser in Windows standard
   mode, problems may occur. The only fix, at this time, is
   to rename the CDMEDIA.CBL file to CDMEDIA.LBC. This means that
   the CD-ROM Media Browser won't be found by CorelBook. No problems
   have been found when using CD-ROM Media Browser in standard
   mode.

   There are known problems printing to printers that don't
   support graphics.

   Tabbing between controls doesn't work correctly on all
   pages.

   The page up and page down controls don't work in list
   boxes. Using these functions flips the page.

   Support for Kodak Photo CDs
   ---------------------------

   The Corel CD-ROM device driver for DOS and Windows (CUNI_ASP.SYS) 
   currently supports Kodak PhotoCD with the following drives:

   Single session       Multi session
   --------------       -------------
   Chinon CDS435        Chinon CDS535
   NEC CDR73            NEC CDR74-1
   NEC CDR73M           NEC CDR84-1
   NEC CDR74            Panasonic CR-532
   NEC CDR83            Philips CDD-521
   NEC CDR83M           Smart & Friendly HS-2200 i/e
   NEC CDR84            Sony CDU-561
   Sony CDU-541         Teac CD-50
   Sony CDU-6211        Texel DM-3024K
   Texel DM-5024        Texel DM-5024K
   Texel DM-3024        Toshiba XM3301 (with multi session upgrade)
   Toshiba XM3301       Toshiba XM3401


   Other drives may be capable of reading Kodak Photo CDs, but have
   not been tested by Corel.


DEVICE INFORMATION
==================

   Using the Pioneer DRM604X in SCSI-1 Mode
   -----------------------------------------

   If you're using a Pioneer DRM604X in SCSI-1 mode with multi-
   session discs, the driver may time-out while waiting for the disc 
   to mount and display a "Not ready reading drive..." error. If this 
   error occurs, use Configuration to set the CD-ROM device driver 
   TIMEOUT option to a value between 30 to 45.


   Additional Sense Codes for the Philps CDD521 Drive
   ---------------------------------------------------

   If a SCSI error occurs, the Philips CDD521 drive reports a 
   sense code which may indicate the cause of the error. The 
   following is a partial list of the sense codes reported by 
   this drive.

   x08: COMMUNICATION FAILURE
	communication failure internal to drive prevented 
	requested operation from being performed.

   x09: TRACK FOLLOWING ERROR
	focusing or radial tracking did not succeed.

   x15: POSITIONING ERROR
	seek to requested location on disc failed.

   x29: POWER-ON RESET OR BUS RESET OCCURRED
	power-on reset or bus reset occurred since last 
	issued command.
