	SCSI DOS Utilities         (c)SyQuest, 1992 - 1994
	Release 3.0                May, 1994
===========================================================================
The SyQuest DOS SCSI UTILITY Release 3.0 is intended for use with SyQuest 
SCSI drives.

SYQUEST RECOMMENDED HOST BUS ADAPTERS:

For the latest information on SyQuest tested Host Bus Adapters,
please dial into the SyQuest bulletin board at the following numbers:

	U.S BBS         (510) 656-0473 or 1 800 249-2440
	EUROPEAN BBS    32-11-683 525

MODIFICATION OF SYSTEM (CONFIG.SYS AND AUTOEXEC.BAT) FILES:   

Running the Installation utility modifies your system files. Please note 
the folowing:

   1.       If the device drivers, SQDRIVER.SYS, ASPI2DOS, and SQEPP.SYS
	    are NOT previously installed in the CONFIG.SYS file, this
	    file will be modified to add the device drivers at the END,
	    but before DBLSPACE.SYS command, if used, in the following
	    order:
			ASPI2DOS.SYS
			SQEPP.SYS
			SQDRIVER.SYS

	    If these device drivers are previously installed, 
	    they will be updated at the same line as before.

	    The PAR.EXE device driver will be added to the BEGINNING
	    of the AUTOEXEC.BAT file, if NOT previously installed. If the
	    driver is previously installed, it will be updated at 
	    the same line as before.

   2.       It may be necessary for you to move these device drivers 
	    from the system files. For example, if you want to load the 
	    drivers (SQDRIVER.SYS, ASPI2DOS.SYS, and SQEPP.SYS) in high 
	    memory, they must be placed after the Memory Manager device 
	    driver in the CONFIG.SYS file. Also, if you have a RAMDRIVE  
	    installed, the device drivers should be placed after 
	    RAMDRIVE device driver in the CONFIG.SYS file, if you want 
	    to keep the same drive letter for your RAMDRIVE.
	    
	    Note: The ASPI Managers ASPI2DOS.SYS and SQEPP.SYS must be
		  installed before the SQDRIVER.SYS driver, in the order
		  shown above.

In the subdirectory SCSI:
	
1. SQPREP.EXE and associated HELP. and INDEX files:
	
To begin a cartridge preparation, type SQPREP and follow the menu 
instructions.  ESC always takes you back out without executing a
function.  The F1 key provides extensive on-line help from any menu.
	
For the user in a hurry or for someone that does not wish to get 
involved with details of partitioning, follow the menu path below:
	
  Select the device from the first screen.
  Check the LED's, and answer Y if the correct LED is on (amber).
  Select Prepare Cartridge For DOS.
  Select Automatic DOS Preparation.
  Answer the prompt screens as they appear, ending with a reboot of 
  your system.
	
Your cartridge should be ready to use - even if you intend to boot from 
it.  For further details or explanations, refer to the Software User's 
Manual.
	 
2. SQDRIVER.SYS
	
Most caching software does not monitor Media Changed status,
so please do not use caching software with a cartridge drive
unless it explicitly states that it supports SyQuest and/or
removable drives. (SMARTDRV 4.0,  and PC-KWIK from Multisoft, Corp.)
	
Installation of SQDRIVER.SYS with no command line parameters should 
work for most systems.
	
For advanced users, the Driver syntax is:
	
  device=[path]SQDRIVER.SYS [/t] [+s] [-s] [/n] [/x] [/l] [/DRIVEx:yyy]
	
Note that in the command line above, the [ and ] characters should not 
be typed; they are used here to indicate that these parameters are optional.
Driver command line parameters are used for special situations.  You 
should always try it without any parameters first.  
	
The following list briefly describes the parameters:
	
  /t   This parameter forces the drive to never issue a request that 
       crosses a track boundary. This may be necessary for DR DOS 6.0 
       and if you also use some versions of DM device driver.
	 
  +s   "s" stands for a digit, 0 - 9, that instructs the driver
	to specifically support the partitions on that device.  To
	specifically support the first device in the system, use
	"+0". To support the third, use "+2", etc.   Note that the
	device specified must be supported by the HBA BIOS.  This
	option is useful if SQDRIVER.SYS can not find a SyQuest
	drive and that SyQuest drive is supported by the HBA BIOS.

  -s   "s" stands for a digit, 0 - 9, that instructs the driver
	to specifically NOT support the partitions on that device.
	To not support the third device, use "-2".  Note that the
	device specified must be supported by the HBA BIOS.  This
	option must be used if you have a Always HBA and the
	driver is mistakenly trying to install your CD ROM drive.
	
  /n   "n" is a digit that indicates the number of volumes to
	reserve for a device at boot time if no volumes were found
	at boot time.  The default is to reserve 1 for DOS versions
	3.31 and above, and to reserve more for DOS versions 3.0
	through 3.30 depends on the drive capacity.
	
  /x    For Zenith DOS 3.3 Plus only.  Forces the driver to handle
	large partitions like Compaq DOS 3.31.
	
  /l    This option asks the driver to lock the SyQuest drives.
	All SyQuest drives with valid media will be automatically
	locked when the driver installs.  You must use turbo.exe
	to unlock your media if you need to change it.  The drive
	will be re-locked as soon as the media is accessed.

  /DRIVEx:yyy   
	This parameter instructs the driver to take over drive letters 
	that were assigned to other volumes."x" stands for physical device 
	number (usually 0, or 1), and yyy is the volume letters you want
	assigned to the physical device.  An example would be /DRIVE1:EF.  
	This is intended only for Zenith DOS 3.21, which automatically 
	reserves four volumes as DOS installed.  It allows you to use one 
	of the reserved drive letters.

3. SQEPPMGR.EXE                

A program used to optimize the data transfer rate across the Printer
Port using the SCSI to Parallel Port Adapter. 
   
The following files are associated with this utility:
	
	$RUN.OVL        IBM*RUN.OVL     SQEPPMGR.DAT    SYS$ERR.DAT
	SYS$MSG.DAT     SYS$HELP.DAT    SQEPPMGR.HLP
   
   The following files are created when this utility is run:

	ASPIINST.CFG    CONFIG.DE~      CONFIG.EXM      DEVICE.CFG

4. SQEPP.SYS

An ASPI device driver for the SCSI to Parallel Port Adapter.

5. PAR.EXE

A TSR program used with the SyDOS SCSI to Parellel Port Adapter.

6. SCREEN.SCS    
   
An ASCII file that defines how the SQSHELL Menu and corresponding utilities 
are configured, if you have only SyQuest SCSI drives installed in your 
Computer.
		  
7. READDOS.TXT

This readme file which can be accessed from the SQSHELL Utilities Menu.

In the subdirectory SYQDIR:

1. SCOPY.EXE, and the associated CSHELP & CSINDEX files.

This utility program helps when copying files to/from a SyQuest cartridge
drive.  CSHELP and CSINDEX are associated files for on-line help (see above).
You will find it most useful if you need to copy files from one cartridge to
another using the same drive.

Please note the following:

The program tries to read in as many files as possible using low and XMS
memory before it writes them back out to the new device.  So make sure you
have a XMS memory manager like HIMEM.SYS installed before you run this 
program.

The program currently has an upper limit of approximately 8,000 files, we 
are working on expanding or removing the limit.

2. UNMOUNTC.EXE

This program allows the BOOT volume to be unmounted if the boot volume
is compressed by DBLSPACE of DOS 6.  See below for more information
regarding DBLSPACE.

No parameter is needed to run this program.

In the subdirectory SYQASPI:        

1. ASPI2DOS.SYS

The ASPI device driver for the Adaaptec 1515 and 1520 SCSI HBAs.

2. SQEPP.SYS
  
An ASPI device driver for the SCSI to Parallel Port Adapter.

APPLICATION AND COMPATIBILITY NOTES:

1. Caching programs must be used with caution, and should be limited to 
   those that support removable drives.  SMARTDRV 4.0 is one such example. 
   You should experiment before starting to use the program by changing 
   cartridges after caching has been enabled.  If you can not get the 
   system to recognize the new cartridge, then the caching program does 
   not support removable drives.  See below for special procedures to follow 
   if you also use Microsoft DBLSPACE to compress your SyQuest drive.

2. You will have to disable your SyQuest driver before you upgrade to DOS 
   6 or compress your SyQuest drive with DBLSPACE.  You can re-enable your 
   SyQuest driver after you finish the process.

3. Depending on how you connect your SyQuest drive to your system, special 
   procedures may have to be followed when using Microsoft DBLSPACE to 
   compress SyQuest drives.

   a. If the volumes are installed by the driver as NEW or DUMMY VOLUMES:
      For users of DBLSPACE 6.0, you must unmount your removable volume 
      before you change a cartridge.  You can mount it back after you 
      change it, if necessary.  DBLSPACE 6.2 automatically unmounts and 
      mounts for you.  SMARTDRV will work correctly automatically.

   b. If your volumes are TAKEN OVER by the SyQuest Driver:
      DBLSPACE 6.2 auto-mount will not work with these volumes, you must 
      manually unmount and mount them before and after you change a 
      cartridge. For the boot volume, the supplied UNMOUNTC.EXE program 
      can be used.
      
      If you also use SMARTDRV.EXE, you must perform this on every one of 
      these volumes before you start SMARTDRV.EXE or you will not be able 
      to change the cartridge.

      If you boot from a SyQuest drive, you must put a copy of COMMAND.COM 
      in the path (specified by the SHELL command in your CONFIG.SYS file) 
      and a copy of DBLSPACE.EXE on the HOST volume of your C:.

      You can find out what kinds of volume you have by reading the messages 
      at the screen when the driver loads.

4. If you run Windows off a cartridge, it is very important to always exit 
   Windows before changing the cartridge.  Failure to do so may result in 
   data corruption.

5. QEMM386.SYS
   
   Do not load SQDRIVER.SYS high with QEMM386.sys version 6 and above if 
   you use a ST01 HBA.  We have noticed data corruption problems when we 
   did so.  We are working with Quarterdeck to solve this problem.
	
   It is safe to use DEVICEHIGH to load SQDRIVER.SYS high with DOS version 
   5.0 and above, as well as QEMM386.sys version 5.X.
	
6. 8-bit HBA and MEMORY MANAGER SOFTWARE
	
   If you use the SyQuest 8-bit host adapter and a Memory Manager or Windows, 
   you may need to identify the HBA to the software.  

   To do this:
	
   a) For Windows 3.x add the statement
      EMMExclude=xxxx-yyyy in your SYSTEM.INI file.  The xxxx is the starting 
      BIOS address (e.g. C800, CC00, DC00, etc.) and the yyyy is the ending 
      address, which is the starting address plus 3FF hex (e.g. CBFF, CFFF, 
      DFFF, etc.).
	
   b) For EMM386.EXE of MS DOS 5.0 and QEMM386 (version 5.X) add x=xxxx-yyyy 
      option to the device driver in your CONFIG.SYS file.  Where xxxx and 
      yyyy are the same as above.
	
   c) For 386MAX add RAM=xxxx-zzzz option to the device driver in your 
      config.sys file.  Where xxxx is the same as above zzzz should be
      xxxx plus 400 hex (e.g. CC00, D000, E000, etc.).
	
   d) For QEMM386 version 6.X, consult your QEMM386 manual. Note that if 
      you use the Stealth feature of QEMM386, SQPREP may not be able to 
      identify the SCSI HBA.
	
      This keeps the memory managers from either attempting to allocate
      the host adapter RAM area as usable memory or map the address space
      into Upper Memory Blocks.
	
      To find out the BIOS starting address of the HBA's, you can run SQPREP 
      /B and select the ADAPTER ROM MAP option.

7. SCSI Host Bus Adapters that come with ASPI drivers
 
   Unless your SyQuest drive is the boot drive, it is best to support
   it through the ASPI driver and not the HBA BIOS.  How this can be
   done depends on the HBA you use.  For example on Adaptec 1542B you
   can either disable the BIOS or set the SyQuest drive to a higher
   SCSI ID.  On the Adaptec 1542C, you can configure the SCSI BIOS to
   ignore the SyQuest drive.  On the Trantor T160 set the ROM BIOS
   disabled.

   Caching HBA's generally do not handle changing of media correctly.
   You should experiment with yours to find out if your HBA does.

8. Seagate ST01 Host Bus Adapter

   If you use any SyQuest drive other than SQ555 as the third drive or
   above, you must not use the orginal BIOS from Seagate.  Call our
   Customer Support for a BIOS upgrade.

9. DR DOS

   SQDRIVER.SYS has many problems with DR DOS 5.0.  We do not
   recommend you installing our driver under it.  With DR DOS 6.0, if
   volume(s) on your SyQuest drive were installed by the built-in
   driver and then taken over by our driver, you must load a patch
   file from Digital Research.  Call their BBS at 408-649-3443 to
   get the patch file rcs.zip.  Without the patch file, you can 
   not change cartridges.

10. COMPAQ Computers running DOS 6.2
    Known incompatibilities:

    When a NON-SCSI drive is used as the boot drive and BIOS is enabled 
    on an Adaptec 1515 card while running MS-DOS 6.2 on a COMPAQ 
    computer, the computer may hang during loading of SQDRIVER.SYS.  
    There are two ways to correct this problem:

    A. Disable the BIOS on the 1515 card.  This is the recommended method.

    B. Modify your config.sys file to work around this problem.

    1.  Press the F8 key while your computer is booting.
    2.  Enter N when asked about the DEVICE=ASPI2DOS.SYS statement
    3.  Edit the CONFIG.SYS file and change the "DEVICE=SQDRIVER.SYS" 
	statement to:
	"DEVICE=SQDRIVER.SYS -1"
    4.  Reboot your system.

    Method (B) is only applicable for SQDRIVER.SYS.  SQPREP program will 
    hang at start up.  You must either disable the BIOS on 1515 or 
    disable your boot drive by setting CMOS drive type to 0 to make 
    SQPREP work.
