version 1.2 or earlier, you must remove any system patches, 
using the existing version of CorelSCSI, before installing 
this software.

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


2.  Installing ASPI Managers
----------------------------

For your convenience, this software includes the ASPI managers 
for many host adapters, which you can install during the 
installation.

If the ASPI manager for your card isn't provided with this
software, you must install the ASPI manager and load it in 
your CONFIG.SYS file before installing this software. If you 
have problems with any ASPI manager, contact the 
manufacturer of your card.

This software provides the following ASPI managers:

NOTE: To help distinguish between the revisions of the DPT 
      ASPI managers, which both use the name DPTDDL.SYS, two
      different file names are used. However, the installation
      renames the selected ASPI manager to DPTDDL.SYS. 

      The DPT ASPI for SCSI BIOS ROM\SMARTROM Version:

        * V.001.K is in the file DPTDDL1K.SYS
        * V.002.B is in the file DPTDDL2B.SYS

To install an ASPI manager that isn't provided with this
software
  
1)  Copy the ASPI manager from the disk 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 installation.

    While the system is rebooting, you should look for 
    status messages from the ASPI manager. If the status 
    indicates an unsuccessful installation, the device driver 
    won't function.
    
  
3.  Loading Device Drivers
--------------------------

During the installation, you're prompted to choose whether
to load the Corel CD-ROM and rewritable device driver into
high memory. If you choose this option and not enough memory
is available, the drivers won't load.

To correct this problem, edit the CONFIG.SYS file. For each
device driver command, replace the DEVICEHIGH keyword with
DEVICE.


4.  Using Memory Managers
-------------------------

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


5.  Using DOS SCANDISK and DBLSPACE
-----------------------------------

Don't compress media you plan to use with Corel's SCSI 
utilities using DBLSPACE or other compressing tools.

Similarly, don't use the DOS SCANDISK command. This command
may display incorrect results about the media.


6.  TOOLS (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. DOS will let you access the original 
logical partitions even though they no longer exist.
 
When you do diagnostic test on your PD System drive
and encounter any error, these errors should not be 
thought of as hardware or media failures unless they occur 
repeatedly while diagnostics is looping continuously.


7.  CorelCDX (Windows and DOS)
------------------------------

To work with your CD-ROM drives, you require a CD-ROM 
extensions program, such as CorelCDX, which interprets the 
CD-ROM file system format. CorelCDX also provides several 
types of caches, including a path table, directory, and data 
cache. These caches are discussed in detail in the Users' 
Manual. As an extension to CorelCDX, CDXCACHE provides an 
extended memory data cache.

CDXCACHE, if enabled, is loaded at the same time as 
CorelCDX. This cache stores information recently read from 
CD-ROM drives in extended memory. When information requested 
by an application is located in the cache, the information 
can be accessed more quickly than re-reading the information 
from the drive.

CDXCACHE uses a least recently used (LRU) algorithm: 
frequently used data remains in the cache and infrequently 
used data is discarded from the cache. CDXCACHE works best 
with database type applications, which repeatedly read 
information from the same areas of a CD.

CDXCACHE can cache the first 16 CD-ROM drives connected to 
your system. The cache page size affects the maximum 
cacheable sector address.

The following CDXCACHE options may appear in the CorelCDX 
section of the CRLSCSI.INI file:

    * 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 available XMS memory, you 
      should disable the extended XMS cache when using 
      CDCOPY.

      You can set XMSSIZE to -1 to use a default cache size, 
      which is equal to one-quarter of the free XMS memory.

      You can also set XMSSIZE to 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.

Both CDXCACHE and Microsoft's SmartDrive program use 
extended memory caching. If you're using SmartDrive version 
5.0, provided with MS-DOS 6.2, you can use SmartDrive rather 
than CDXCACHE. However, CDXCACHE has smaller overhead and 
operates faster then SmartDrive. 

SMARTDRV.EXE 5.0 is designed to work exclusively with 
Microsoft's MSCDEX CD-ROM driver. However, Corel's 
PATCH_SD.COM modifies SMARTDRV.EXE to recognize CorelCDX as 
a valid CD-ROM driver.

PATCH_SD creates a copy of the existing SMARTDRV.EXE program 
and stores the copy as SMARTDRV.MSC. If you've made changes 
to SMARTDRV.EXE version 5.0 that change its size, such as 
compressing the file, from 45145 bytes, PATCH_SD won't work.

To modify SmartDrive to recognize CorelCDX

1)  At the command prompt, enter PATCH_SD.
   
2)  Check your AUTOEXEC.BAT file to ensure that CorelCDX is 
    loaded before SmartDrive; otherwise, SmartDrive won't 
    find, and therefore cache, CD-ROM drives. Since 
    SmartDrive is loaded after CorelCDX, you can't use the 
    CorelCDX /UNLOAD command.
   
3)  Use the CorelCDX section of Configuration to set the XMS 
    Cache Size option to Disable. The CDXCACHE is enabled, 
    by default. If you don't disable the cache, both 
    CDXCACHE and SmartDrive will cache data, using twice 
    the necessary amount of extended memory.
   
4)  Reboot your system to reinstall SMARTDRV.EXE.

Miscellaneous Information:

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

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.

The DRIVERNAME option of the CRLSCSI.INI file provides the 
required name of the CD-ROM device driver, which should be 
the same as the value of the DRIVERNAME option in the [CD-
ROM Drivers] section of this file. CD-ROM device drivers are 
numbered starting from MSCD001.

If CorelCDX can't find driver names in the CRLSCSI.INI file 
or if the CRLSCSI.INI file is missing, CorelCDX will try to 
locate and initialize the CD-ROM device drivers named, by 
default, 'MSCD001' and 'MSCD099'.


8.  DOSTOOLS (DOS)
------------------

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.

When you do diagnostic test on the PD System drive
and encounter any error, 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.


9.  Using PC-DOS with Corel's DOS Utilities
-------------------------------------------

If you're using PC-DOS version 5.0/V in Kanji mode, you must 
switch to US mode before using the DOS utilities; otherwise, 
the utilities won't run.

To switch to US mode, enter the following at the command 
prompt:
 
    CHEV   US  /f


10.  Undocumented Commands
--------------------------

The following commands are not documented in the Users' Manual: 

SS

Displays a menu from which you can select a host adapter. 
This utility scans the selected host adapter and lists the 
SCSI devices detected.


11.  Support for Kodak Photo CDs
--------------------------------

The CD-ROM device driver, which is named CUNI_ASP.SYS 
currently supports Kodak Photo CDs including multi-session
type.
