3.  32-Bit Disk Access Support
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

Adaptec EZ-SCSI includes 32-Bit Disk Access support for Windows 3.1,
Windows 3.11, and Windows for Workgroups 3.11.  To enable this support,
simply run the "32-Bit Disk Access" utility (FASTSCSI.EXE), and follow the
instructions.  Please note the following:

o  Our 32-Bit Disk Access device drivers only support Adaptec's bus-
   mastering line of SCSI host adapters.  These host adapters use the
   following ASPI managers:

       ASPI4DOS.SYS
       ASPI7DOS.SYS
       ASPI8DOS.SYS
       ASPIEDOS.SYS

   If your host adapter does not use one of these ASPI managers, our 32-Bit
   Disk Access utility will still allow you to enable or disable SCSI write
   caching.

o  If you are running Windows for Workgroups 3.11, and you are not able to
   get 32-Bit File Access to work properly, the following comes from
   Microsoft's Windows for Workgroups resource kit:

   "32-bit File Access will not enable on a drive on which there are open
   files during the initialization process of 32-bit File Access.  Because
   of this, 32-bit file access cannot be enabled through the Control Panel
   Virtual Memory dialog when using a temporary swap file.  The temporary
   swap file is opened before 32-bit File Access initializes and 32-bit
   File Access will not be able to enable on the drive where the temporary
   swap file is located.  There normally should not be any open files at the
   time when 32-bit File Access is initializing.  If there are open files,
   they are probably the result of some real mode TSR or a 3rd-party VxD."

o  When 32-Bit Disk Access is enabled, you need to have the latest WINASPI.DLL
   file in your Windows' SYSTEM subdirectory.  If an older revision is being
   used, you will experience protection faults when running "ASPI for Windows"
   applications.  EZ-SCSI 3.11 (and later) will automatically install the
   correct WINASPI.DLL file.  There are, however, a few older packages that
   install the older WINASPI.DLL file.  If you are experiencing protection
   faults, while running "ASPI for Windows" applications, you should check
   the date of WINASPI.DLL in your Windows' SYSTEM subdirectory.  If it is
   dated 1995 or later, you have the correct file.

o  32-Bit Disk Access, in general, does not significantly improve performance
   under Windows 3.1 or Windows 3.11.  To get optimal disk performance, you
   should use Windows for Workgroups 3.11 which, in addition to 32-Bit Disk
   Access, includes support for 32-Bit File Access.  We are seeing the
   larger performance gains by enabling 32-Bit Disk Access, 32-Bit File
   Access, and SCSI write caching.

o  Our 32-Bit Disk Access driver cannot be used if you are also using our
   SCSI Power Management driver.  If you attempt to load both drivers, an
   appropriate error message will appear when you run Windows.  If you
   encounter this message, and if you prefer 32-Bit Disk Access over SCSI
   Power Management, simply run Adaptec's 32-Bit Disk Access utility and
   select the "Install" option.  It will detect the conflict and remove
   the SCSI power management device driver.

o  32-Bit Disk Access only supports drives under BIOS control (INT 13h
   drives).  This does NOT include drives under the control of ASPIDISK.SYS.
   Most of our SCSI host adapters allow you to have up to 8 SCSI drives
   under BIOS control.

o  There is a known problem in Windows 3.1 and Windows 3.11 (does not
   affect Windows for Workgroups 3.11) in that its 32-Bit Disk Access
   solution only supports up to two hard drives.  For example, if you have
   three hard drives under BIOS control, only the first two would be under
   32-Bit Disk Access.  If you encounter this situation, you can upgrade
   to Windows for Workgroups 3.11 which does not exhibit this limitation.

o  Our 32-Bit Disk Access driver will not work properly in your system if
   you have an AHA-1540/1542 or AHA-1640, and you have more than 16 MBytes of
   RAM.  You should not use our 32-Bit device drivers if you have this type
   of configuration.  This is not an issue with any other Adaptec SCSI host
   adapter (ISA bus has a limitation of DMA'ing only into the first 16
   MBytes).

o  If you are running Windows 95, or OS/2 Warp (and have installed Win-OS/2
   support), you can still use our 32-Bit Disk Access utility to enable or
   disable SCSI write caching.

o  Adaptec's 32-Bit Disk Access utility provides an uninstall option that
   will remove our 32-Bit device drivers.  If you would like to manually
   remove the drivers, remove the following entries from the [386Enh] section
   of your SYSTEM.INI file:

   device=fastscsi.386
   device=aha1540.386
   device=aha1740.386
   device=aic7770.386
   device=aic7870.386

   (NOTE:  Not all of these drivers will be present in your SYSTEM.INI file.
   Depends on what type of host adapter you have.)

o  Enabling SCSI write caching can improve the overall performance of your
   system.  Many SCSI hard drives ship factory default with SCSI write
   caching disabled.  Our 32-Bit Disk Access utility will allow you to
   enable or disable SCSI write caching on a per device basis.  We have
   found a few older drives causing system hangs, under intense disk I/O,
   when write caching is enabled.  In the unlikely event that you encounter
   this situation, you can disable SCSI write caching at any time by running
   our 32-Bit Disk Access utility.

o  On some systems, when you enable 32-Bit Disk Access, Windows' Control Panel
   incorrectly loads the IDE 32-Bit Disk Access driver even if you only have
   SCSI disk drives.  This will typically result in an error message, while
   loading Windows, similar to the following:

   "The Microsoft Windows 32-bit disk driver (WDCTRL) cannot be loaded on
   this computer because of interrupt conflicts."

   If you encounter this, simply remove the line "device=*wdctrl" from the
   [386Enh] section of your SYSTEM.INI file.  Another option is to run our
   32-Bit Disk Access utility.  It will detect that your configuration is
   incorrectly loading the IDE device driver and ask if you would like us to
   remove it.

o  We have seen one computer, with more than one SCSI host adapter in the
   system, not work properly with 32-Bit Disk Access.  If you encounter this
   problem, you should disable 32-Bit Disk Access.

o  For the technical user:  If you select to turn on SCSI write caching,
   we will also turn on the AWRE (Automatic Write Reallocation Enabled) bit
   in the Read/Write Error Recovery Page.  If you select to turn off SCSI
   write caching, the AWRE bit is set back to the factory default setting
   (some drives ship factory default with AWRE set).

*    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.

**** These jukebox CD-ROM drives are fully supported.  However, you will need
     to add /L to the ASPICD.SYS command line, in your CONFIG.SYS, to
     properly support these devices.  You may also need to modify your
     LASTDRIVE statement in your CONFIG.SYS.

6.  Scanner Support
=-=-=-=-=-=-=-=-=-=

Hewlett-Packard's driver for HP ScanJet II scanners is included with Adaptec
EZ-SCSI.  This driver is named SJIIX.SYS and is designed to function with
Adaptec's ASPI managers.

Installation of the driver is easy.  Simply run Adaptec EZ-SCSI.  Adaptec
EZ-SCSI automatically detects your HP scanner and installs SJIIX.SYS into
the appropriate section of your CONFIG.SYS file.  You can then install
HP's DESKSCAN software if it is not already installed.

SJIIX.SYS supports the following applications using TWAIN or the
application's scanning utility:

Aldus: PhotoStyler
Arkenstone: Arkenstone Reader II
Caere: FaxMaster, OmniPage Direct, OmniPage Professional, PageKeeper
Calera: TrueScan, WordScan, WordScan Plus
Corel: Corel Draw
Delrina: WinFax, WinFax Pro
Eclipse systems: Eclipse fax
ExperVision: TypeReader
Image-In: Image-In
Intel: Satisfaction
Light Source: Ofoto
Micrografx: Picture Publisher
Pixel Translations: Open Book
RIX Software: WinRix
Westbrook: File Magic
WordStar/ZSoft: Publisher's Paintbrush, PhotoFinish


EPSON SCANNER SUPPORT

To connect your PC system with the SCSI interface on an Epson scanner, first
install an Adaptec SCSI Host Adapter interface board and EZ-SCSI software
onto your PC system before loading the Epson Scanner Utility and TWAIN driver.
The Epson scanner TWAIN driver should be included with your Epson scanner.


=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
7.  SETUP Command Line Options
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

There are a couple of command line options that are available with the
Windows version of EZ-SCSI (SETUP.EXE):

Option:        noctl3d
Example:       c:\setup noctl3d
Description:   EZ-SCSI for Windows uses a Dynamic Link Library (DLL) called
               CTL3D.DLL that gives its dialog boxes the 3-D gray-box look.
               This command line option disables the loading of this DLL.
               Note that EZ-SCSI defaults to not loading this DLL if you are
               using Central Point's Desktop (e.g. PC Tools for Windows 1.0).


=-=-=-=-=-=-=-=-=
8.  ASPI2DOS.SYS
=-=-=-=-=-=-=-=-=

ASPI2DOS.SYS is Adaptec's ASPI managers for AIC-6260/6360/6370 based SCSI
host adapters.  Running Adaptec EZ-SCSI will automatically detect which host
adapter you have installed, which ASPI manager needs to be loaded, and what
the correct command line switches are.

o  If you are using an Adaptec APA-1460 SlimSCSI, make sure you have PCMCIA
   Card & Socket Services installed BEFORE running Adaptec EZ-SCSI.

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.

o  If you have an APA-1460 (SlimSCSI) in your system and are installing 
   ASPI2DOS.SYS manually,  you will need to add the following command
   line switch to ASPI2DOS.SYS in your CONFIG.SYS file:

         DEVICE = C:\SCSI\ASPI2DOS.SYS /D /PCMCIA /Z

o  If you cannot suspend/resume properly on an AcerNote 735c, with an
   APA-1460 (SlimSCSI), you're probably experiencing an I/O conflict
   between the APA-1460 and your laptop.  The AcerNote uses port 35F for
   video control.  You'll need to manually exclude this I/O port.  With
   SystemSoft Card and Socket Services, you can do this by editing the
   CSALLOC.INI file and adding the line:

         ioexclude=35F

o  If you are using the Gateway 2000 Colorbook laptop with an Adaptec
   APA-1460 (SlimSCSI), ASPI2DOS.SYS may fail during driver installation.
   If you encounter this problem, you will need to go into the motherboard
   CMOS setup utility and disable the "FastBoot" option.

o  SCAM stands for "SCSI Configured AutoMagically."  Without SCAM support,
   the user needs to set jumpers or switches to assign a unique SCSI ID to
   each SCSI device.  With SCAM support, a host adapter can determine which
   SCSI IDs are not in use, and assign a free ID to a SCAM capable SCSI
   device.  You can enable SCAM support by adding /SCAM+ to your ASPI2DOS.SYS
   command line.  For example:

         DEVICE = C:\SCSI\ASPI2DOS.SYS /D /SCAM+

   This will work with any AIC-6260/6360/6370 based SCSI host adapter that
   does not have a BIOS enabled on the host adapter.  If the host adapter
   has a BIOS, and it is enabled, the command line switch is ignored.  If
   you have a SCAM capable BIOS (e.g. AHA-1530P), then you can enable or
   disable SCAM support by running SCSISelect.

   NOTE:  There are very few SCAM capable SCSI devices available today.
   Special firmware is required on the SCSI device.  If you do not have
   such a device, there is no need to use the /SCAM+ command line switch.


=-=-=-=-=-=-=-=-=
9.  ASPI8DOS.SYS
=-=-=-=-=-=-=-=-=

ASPI8DOS.SYS is Adaptec's ASPI manager for AIC-7850/7870 based PCI SCSI host
adapters.  Running Adaptec EZ-SCSI will automatically detect which host
adapter you have installed, which ASPI manager needs to be loaded, and what
the correct command line switches are.

o  If you have an Adaptec PCI SCSI host adapter installed in your system,
   and you have EMM386.EXE loaded from MS-DOS versions up to 6.2, your
   system might hang if loading the ASPI manager after EMM386.EXE.  This has
   been fixed in the EMM386.EXE that ships with MS-DOS 6.22 and later.
   If you experience this problem, you will either need to load ASPI8DOS.SYS
   before EMM386.EXE, or upgrade to MS-DOS 6.22 or later.  If the ASPI
   manager detects a conflict, a message will be shown explaining how to
   work around the problem.  Other ASPI modules (e.g. ASPICD.SYS) can
   continue to be loaded high.

o  There are several techniques for a driver to determine if its PCI SCSI
   host adapter is installed in your system.  ASPI8DOS.SYS will determine
   which is the best method, and has been written to work around the
   EMM386.EXE problems discussed above.  There are three command line
   switches you can use to force the ASPI manager to use a specific
   method.  These are:

         /MB - This command line switch will force the driver to use the
               PCI BIOS calls (INT 1Ah) to scan for PCI SCSI host adapters.
         /M1 - This command line switch will force the driver to use the
               "Mechanism 1" method for scanning for PCI SCSI host adapters.
         /M2 - This command line switch will force the driver to use the
               "Mechanism 2" method for scanning for PCI SCSI host adapters.

   For example, if you want to force the ASPI manager to find your PCI SCSI
   host adapter using PCI motherboard BIOS calls, your CONFIG.SYS would be:

         DEVICE=C:\SCSI\ASPI8DOS.SYS /D /MB

   NOTE:  Most PCI systems do not support all three methods for scanning
   for PCI cards.  It is recommended that you let the ASPI manager determine
   which method is suitable.

o  If you would like ASPI8DOS.SYS NOT to reset the SCSI bus, during driver
   initialization, you can use the /NORST command line switch.  For example:

         DEVICE=C:\SCSI\ASPI8DOS.SYS /D /NORST

   NOTE:  If the host adapter BIOS is disabled, the /NORST switch is ignored
          and the SCSI bus will be reset during driver initialization.

o  SCAM stands for "SCSI Configured AutoMagically."  Without SCAM support,
   the user needs to set jumpers or switches to assign a unique SCSI ID to
   each SCSI device.  With SCAM support, a host adapter can determine which
   SCSI IDs are not in use, and assign a free ID to a SCAM capable SCSI
   device.  If you have an Adaptec AHA-2930, with SCAM support enabled, you
   should use the /NORST switch so that SCSI IDs are not reset during driver
   initialization.  For example:

         DEVICE = C:\SCSI\ASPI8DOS.SYS /D /NORST


=-=-=-=-=-=-=-=
10.  MA358.SYS
=-=-=-=-=-=-=-=

MA358.SYS is Adaptec's ASPI manager for its APA-358/358A parallel port SCSI
host adapters.  Running Adaptec EZ-SCSI will automatically detect which host
adapter you have installed, which ASPI manager needs to be loaded, and what
the correct command line switches are.

o  MA358.SYS, by default, will automatically detect the type of parallel
   port you are using.  You can use the /Mnm switch to force a specific mode,
   and to set the amount of time that the MiniSCSI "Fast" read and write
   cycles are delayed (parallel ports on some computers require delays).
   You must specify values for both 'n' and 'm'.

   The 'n' specifies the amount of delay.  Allowable values for 'n' are 0
   through 7, with each number representing a 125-nanosecond (ns) increment.
   A value of 7, for example, adds an 875 ns (7x125) delay to the cycles.
   The default of 0 specifies no delays.

   The 'm' parameter determines the mode.  The allowable values are shown in
   the following table:

   Value of 'm'    Meaning
   ------------    ----------------------------------------------------------
        0          Auto-detect mode (the default).  Automatically detects the
                   the type of port and configures the APA-358/358A for EPP
                   if that port is detected to support EPP mode, otherwise
                   the port is set up as a standard parallel port.
        2          Forces unidirectional mode.
        4          Forces bidirectional mode.
        8          Assumes EPP 8-bit bidirectional mode.  For this to work,
                   the parallel port must be set for EPP mode in the CMOS
                   setup program or by configuring jumper settings on your
                   EPP I/O card.  For instructions on using the CMOS setup
                   program, see your motherboard documentation.  For
                   instructions on configuring jumpers on your EPP I/O card,
                   see your EPP I/O card documentation.

   For example, if your parallel port is configured for EPP mode, and you
   would like the default read/write delay, your CONFIG.SYS would contain the
   following:

         DEVICE=C:\SCSI\MA358.SYS /m08

   If you change the MA358.SYS options in the config.sys file, turn the
   computer OFF and then ON again to have the changes take effect. (Do not
   simply reboot the computer using Ctrl-Alt-Del.)

o  If you have an original NEC Ultralite Versa laptop, and MA358.SYS is unable
   to detect the APA-358/358A SCSI host adapter, you should use the /m20
   command line switch.  For example:

         DEVICE=C:\SCSI\MA358.SYS /m20

o  If you are using the APA-358 with an NEC Versa E or Versa V system, which
   uses the Western Digital Super I/O chip for FPP Parallel Ports (Chip
   #WD76C30), you should use the MA358NEC.SYS ASPI Manager in your CONFIG.SYS
   file instead of the standard MA358.SYS ASPI Manager.

o  If you are using an IBM ThinkPad 720 series computer, you should use the
   MA358IBM.SYS ASPI manager in your CONFIG.SYS file instead of the standard
   MA358.SYS ASPI manager.

o  When using the APA-358/358A, you should not configure your parallel port
   for ECP mode.  Instead, you should configure the port for EPP mode.

o  MA358.SYS only supports one APA-358/358A in a system.

o  If you are using the APA-358/358A, and you are backing up from a SCSI disk
   drive to a SCSI tape drive, and you are using SMARTDRV, we recommend that
   you disable SMARTDRV write caching.  Leaving write caching enabled can
   cause the backup to fail.


=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
11.  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 AHA-2740W/2742W or AHA-2940W (Wide SCSI Host 
   Adapter), the SCSI Interrogator for Windows (SHOWSCSI.EXE) will only 
   show icons for SCSI IDs 0-7.  You will not see IDs 8-15.

o  Backup Basics, by default, does not support backing up removable hard
   drives.  To enable this, you can modify the BEWINS.INI file in your
   WINDOWS' subdirectory.  In the [Backup Engine] section, add the line:

         Special Word = 0x02

o  If you have a Trantor T160/T260 SCSI host adapter, EZ-SCSI will no longer
   scan for this adapter if you select the default installation option.  In
   this case, you will need to select the custom installation option, and
   manually select the adapter, to properly install Adaptec EZ-SCSI.

o  The SCSI Power Management Utility is not compatible with the Trantor 
   T160 and T260 SCSI Host Adapters.

o  The SCSI Power Management Utility requires that the following line
   be present in your SYSTEM.INI file under the [386Enh] section:

         device=VSCSIPWR.386

   The first time you run SCSI Power Management you will be prompted to 
   install the above driver.  If you wish to disable the SCSI Power 
   Management functions, you can remove this line from your SYSTEM.INI 
   file in your WINDOWS subdirectory.
