0. General Information
=-=-=-=-=-=-=-=-=-=-=-=

Sound Blaster 16 SCSI-2(TM) is compatible with Adaptec AHA-1510/AHA-1510A. Therefore, 
references to Adaptec AHA-1510/AHA-1510A are applicable to Sound Blaster 16 SCSI-2(TM)
with the exception that Sound Blaster 16 SCSI-2(TM) does not support external SCSI devices.
To connect to external SCSI devices, you will require the Sound Blaster SCSI External
Extension Card available at your nearest authorised dealer or call the Creative Sales 
Hotline number 1-800-998-5227 (for USA/Canada).

Sound Blaster 16 SCSI-2(TM) does not support bootable devices.

*    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.

4.  ASPI for Windows
=-=-=-=-=-=-=-=-=-=-=

If you would like to run "ASPI for Windows" applications (e.g.  Arcada
Backup, Central Point Backup, The Norton Backup etc.), you should copy
the files WINASPI.DLL and VASPID.386 to your Windows' SYSTEM subdirectory.
These two files will be decompressed when you run Adaptec EZ-SCSI.  For
example:

copy c:\scsi\winaspi.dll c:\windows\system
copy c:\scsi\vaspid.386 c:\windows\system
del c:\scsi\winaspi.dll
del c:\scsi\vaspid.386

NOTE:  NO changes are required to any of your .INI files.  Simply copy these
two files to your Windows' SYSTEM subdirectory.


=-=-=-=-=-=-=-=-=-=-=
5.  Floptical Support
=-=-=-=-=-=-=-=-=-=-=

ASPIDISK.SYS has been modified to support Insite and IOMega floptical
drives.  For those of you already familiar with ASPIDISK.SYS and AFDISK.EXE,
using floptical drives is a bit different.  Do NOT use AFDISK.EXE to
format media inserted in your floptical drive.  You can use SCSIFMT.EXE
to low-level format the media if necessary.  To do a DOS format of your
media, simply insert the media into the floptical drive and run the DOS
FORMAT utility (run EZ-SCSI first).


=-=-=-=-=-=-=-=
6.  ASPIBUF.SYS
=-=-=-=-=-=-=-=

The ISA bus is limited to 24 bits of address.  2^24 = 16 MBytes.  What does
this mean?  It means that an ISA card that uses DMA cannot physically
access memory beyond 16 MBytes of RAM.  This is a limitation of the ISA
bus.

The 16 MByte issue is not a limitation with PCI cards, EISA cards, VL cards,
or PIO cards.  It is only an issue with an ISA card that uses DMA such as
the AHA-1540/1542.  ASPIBUF.SYS is an ASPI double-buffering driver that
you load immediately after ASPI4DOS.SYS (e.g. before ASPICD.SYS, ASPIDISK.SYS,
etc.).  It, along with ASPI4DOS.SYS, must both be loaded low before EMM386
(or QEMM, 386MAX, etc.).  It intercepts ASPI and INT 13h commands and double-
buffers both so that these data transfers occur within the first 16 MBytes
of RAM.  ASPIBUF.SYS is intelligent enough to not double-buffer if the
ASPI or INT 13h buffer is already within the first 16 MBytes of RAM.  It is
only designed to work with ASPIDISK.SYS, ASPICD.SYS, and INT 13h commands.
Other ASPI drivers and/or applications may or may not work.  ASPI FOR
WINDOWS APPLICATIONS (E.G. SHOWSCSI.EXE) WILL BE DISABLED ONCE THIS DRIVER
IS LOADED.

By default, ASPIBUF.SYS will allocate a 16K buffer for double-buffering.  You
can specify the size (2K-64K) by using the size= command line switch.  For
example:

device=c:\scsi\aspi4dos.sys /d
device=c:\scsi\aspibuf.sys /size=8
device=c:\scsi\aspidisk.sys /d


=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
7.  SMARTDRV 5.0 and XA formatted CDs
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

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


=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
8.  ASPI8DOS.SYS Information
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

The driver ASPI8DOS.SYS was added after the user's manual went to print.
For information on the available command line switches, refer to the
ASPI7DOS.SYS section of your user's manual.  ASPI8DOS.SYS uses the same
switches that ASPI7DOS.SYS does.  ASPI8DOS.SYS supports the following PCI
SCSI host adapters:

Adaptec AHA-2940
Adaptec AHA-2940W
Adaptec AIC-7870 based SCSI host adapters


=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
9.  Troubleshooting/Limitations
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

o  If you have an Adaptec PCI SCSI host adapter installed in your system,
   and EZ-SCSI for DOS does not detect your host adapter, try running
   EZ-SCSI with the /pci command line switch.  For example:

   a: <Enter>
   ezscsi /pci <Enter>

   Note that if your system has EMM386.EXE loaded, from MS-DOS versions up
   to 6.2, your system might hang when using the /pci switch.  This has been
   fixed in MS-DOS 6.21 and later.  If you experience this problem, you
   should not load EMM386.EXE when running EZ-SCSI for DOS.  The same applies
   to SCSIFMT.EXE.  EZ-SCSI for Windows does not exhibit this problem and
   should find your Adaptec PCI SCSI Host Adapter regardless of your PCI
   system and whether or not you have EMM386.EXE loaded.

   ASPI8DOS.SYS can be loaded high.  However, due to the EMM386.EXE problem
   mentioned above, some PCI systems will hang if loading ASPI8DOS.SYS after
   EMM386.EXE.  If you experience this problem, you will either need to load
   ASPI8DOS.SYS before EMM386.EXE, or upgrade to MS-DOS 6.21 or later.  Other
   ASPI modules (e.g. ASPICD.SYS) can continue to be loaded high.

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.
