====================
Troubleshooting Tips
====================

ASPI2DOS.SYS
------------

   ASPI2DOS.SYS is the Adaptec ASPI manager for AIC-6260/6360/6370 based SCSI
   host adapters.  Adaptec EZ-SCSI automatically detects 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-1425/50/50A/60/60A 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-1425/50/50A/60/60A 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-1425/50/50A/60/60A (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-1425/50/50A/60/60A (SlimSCSI), you're probably experiencing an I/O conflict
      between the APA-1425/50/50A/60/60A 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-1425/50/50A/60/60A (SlimSCSI), ASPI2DOS.SYS may fail during driver installation.
      If you encounter this problem, you will need to run the CMOS setup utility
      and disable the "FastBoot" option.
   
   o  The following note only applies to users with SCAM capable SCSI devices. Please ignore
      it if you do not have such a device. 
      SCAM stands for "SCSI Configured AutoMagically."  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. 
      Normally SCAM is not enabled, and you need to set switches on the back of all of 
      your SCSI peripherals to assign them unique SCSI IDs.   
      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.

ASPI8DOS.SYS
------------

   ASPI8DOS.SYS is Adaptec's ASPI manager for AIC-7850/7855/7870 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

      If you would like ASPI8DOS.SYS to always reset the SCSI bus, during
      driver initialization, you can use the /RESET command line switch.
      For example:

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

   o If there are more host adapters that ASPI8DOS can support, ASPI8DOS will display "Not enough 
     memory for all host adapters". In this case, the user should manually add more lines of 
     "DEVICE=ASPI8DOS.SYS" to CONFIG.SYS to support the extra host adapters. EZ-SCSI only installs  one entry in config.sys for ASPI8DOS.SYS.

MCAM18XX.SYS
------------

   MCAM18XX.SYS is Adaptec's ASPI manager for its AHA-2920/2920A 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  The command line switches for MCAM18XX.SYS are currently not documented
      in our on-line "Device Driver Reference" Windows help file.  The
      following command line switches are supported:

        /u-     - Force Asynchronous Data Transfers on a Host Adapter.
        /norst  - Disables Hard Reset during initialization.
        /y      - Disables parity checking.
        /m1     - Force PCI bus scanning using the "Mechanism 1" method.
        /m2     - Force PCI bus scanning using the "Mechanism 2" method.
        /mb     - Force PCI bus scanning using INT 1A.
        /l      - Enable multiple LUN support

   o  If installing the AHA-2920/2920A under Windows 3.1/3.11, Adaptec EZ-SCSI
      will automatically install the AHA2920.386 and AXPT.386 device drivers.

      The following options are supported by AHA2920.386.  To enable an
      option, add the following to the [386Enh] section of your SYSTEM.INI
      file:

        AHA2920 = [/l-] [/u-] [/y]

        /l-      - Disables multiple LUN support.
        /u-      - Force Asynchronous Data Transfers on a Host Adapter.
        /y       - Disables parity checking.

      The following options are supported by AXPT.386.  To enable an option,
      add the following to the [386Enh] section of your SYSTEM.INI file:

        EZSCSI_OPTIONS = [/d]

        /d       - Displays version, adapter, and device information.


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 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.

  HARD DISK SUPPORT
=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=

Windows 3.1/3.11 and DOS
------------------------

   DOS and Windows 3.1x include built-in support for SCSI hard drives if your
   new drive is under BIOS control (e.g. you booted from it).  Please refer
   to your host adapter documentation to learn more about whether or not
   your SCSI host adapter includes an on-board ROM BIOS.  In this case, you
   can follow these steps:

   1.)  Boot to DOS.
   2.)  Run FDISK to partition your new drive as you desire.
   3.)  Reboot your operating system.
   4.)  Run FORMAT on your newly created drive letter(s)

   If your new SCSI hard drive is not under BIOS control, you can follow
   these steps:

   1.)  Install Adaptec EZ-SCSI for DOS
          - Insert EZ-SCSI DOS/Win 3.1x diskette into a:\
          - Run DOSINST.BAT
   2.)  Reboot your system.
   3.)  From DOS, run AFDISK.EXE which is located in your
        Adaptec EZ-SCSI subdirectory (e.g. C:\SCSI).  
   4.)  Partition your new media as you desire.
   5.)  Reboot your operating system.
   6.)  At this point, your new drive is under ASPIDISK.SYS control
        (Adaptec's disk driver for DOS).
   7.)  Although optional, we recommend that you run DOS FORMAT on your
        new drive letter(s) so that the drive can be scanned for defects.


=-=-=-=-=-=-=-=-=-=-=-=
REMOVABLE DISK SUPPORT 
=-=-=-=-=-=-=-=-=-=-=-=

Windows 3.1/3.11 and DOS
------------------------

   To prepare your removable media for use under Windows 3.1/3.11 and DOS,
   you can follow these steps.

   1.)  Install Adaptec EZ-SCSI for DOS
          - Insert EZ-SCSI DOS/Win 3.1x diskette into a:\
          - Run DOSINST.BAT
   2.)  Reboot your system.
   3.)  From DOS, run AFDISK.EXE which is located in your
        Adaptec EZ-SCSI subdirectory (e.g. C:\SCSI).  
   4.)  Partition your new media as you desire.
   5.)  Reboot your operating system.
   6.)  At this point, your new drive is under ASPIDISK.SYS control
        (Adaptec's disk driver for DOS).
   7.)  Although optional, we recommend that you run DOS FORMAT on your
        new drive letter(s) so that the drive can be scanned for defects.

   Below is additional information you may find useful:
 
   o  Adaptec EZ-SCSI supports both 512 byte/sector media and 1024 byte/
      sector media.

   o  If you would like to reserve multiple drive letters for your removable
      media, you can use the /r command line switch.  For example, if you
      would like ASPIDISK.SYS to reserve two drive letters for your removable
      media, you would have the following in your CONFIG.SYS:

         device=c:\scsi\aspidisk.sys /d /r2

   o  Support for the Panasonic PD drive is also included.  Note that you
      should leave this device jumpered in its default two LUN mode.

CD-ROM SUPPORT
=-=-=-=-=-=-=-=


Windows 3.1/3.11 and DOS
------------------------

   Adaptec's CD-ROM driver for DOS/Windows, ASPICD.SYS, has been written to
   support any SCSI-2 CD-ROM drive and most SCSI-1 CD-ROM drives.  Simply
   run Adaptec EZ-SCSI and the correct additions will be made to your
   CONFIG.SYS and AUTOEXEC.BAT.

   Adaptec EZ-SCSI has been tested with CD-ROM drives from the following
   vendors:

         AIWA
         Compaq
         Chinon
         Denon
         Goldstar
         Hitachi
         IBM
         LMS
         Matsushita
         NEC
         Panasonic
         Nakamichi
         Philips
         Pioneer
         Plasmon Data
         Plextor

        NEC CDR 84
        NEC CDR 210 (NOTE: 210P does support parity)

      Please consult your host adapter documentation on how to disable parity
      support on your SCSI host adapter.

   o  The following jukebox CD-ROM drives are fully supported:

        Nakamichi MBR-7
        Pioneer   DRM 600
        Pioneer   DRM 604X
	Pioneer   DRM 624X

      A drive letter will be assigned for each CD.  

   o  Some older SCSI CD-ROM drives do not support synchronous negotiation
      properly.  If you encounter problems using your CD-ROM drive, try
      disabling synchronous negotiation.  Please refer to your host adapter
      documentation on how to do this.

o  In rare circumstances, you may encounter problems with Windows 3.x and
   DOS reading your CD-ROM drive.
   For example, you change the contents of the CD-ROM drive, but when you run 
   DIR, the contents of the previous CD is displayed instead of the new CD's.
   Or you may see multiple drive letters assigned to your single CD-ROM drive. 
   One solution is to add the /NOLUN switch to the aspicd.sys line in config.sys.
   We have seen the former problem with the Sony 55s - an older double speed
   CD-ROM drive, and the latter problem with an older SCSI1 Panasonic drive.
   By adding the /NOLUN switch, you will however loose support
   for any CD Changers or PD drives that you also have connected to your PC.
