This is the release of the IN-2000 Advanced SCSI Programming
Interface (ASPI) Manager for DOS.  The ASPI Manager is an 
industry standard software "front end" that allows the 
IN-2000 SCSI host adapter to run any ASPI compliant software
package (eg. CorelSCSI!, Central Point Utilities, Sytos Plus etc.).

Follow the instructions below for installation of the IN-2000
ASPI Manager for DOS.

This version of the IN-2000 ASPI manager (VCN: 461-12.8) has two command 
line switches available: "/s" to enable synchronous transfers and "/d" to
disable disconnect/reselect.

Copy the file ASPIDRVR.SYS to your boot drive and add the
following line to your CONFIG.SYS as follows:

        DEVICE=d:\path\ASPIDRVR.SYS [/s] [/d]

        where d:\path is the drive and directory to which you copied the 
        ASPI manager.

You may wish to enable synchronous transfers to gain higher performance with
"synchronous capable" SCSI devices.  However, there are some "synchronous 
capable" SCSI devices (usually CD-ROM drives) that do not handle synchronous
negotiations the same as most synchronous devices.  With these devices, 
synchronous support should remain disabled (default).

There are only a few SCSI devices that will not support disconnect/reselect. 
If you have one or these devices, you must use the "/d" switch to disable 
that feature from the ASPI manager.  If you do not disable 
disconnect/reselect with any of these non-supported devices, the ASPI manager
will probably hang durring boot.

NOTES:
======

If you are using an IN-2000 without any hard drives attached,
the ASPI Manager will display the following message:

                Always Int 13 handler not loaded

This is not a problem, since the Int 13 handler is used only to
handle disk requests for DOS.  The IN-2000 BIOS may be disabled
if you are using only non-disk peripherals such as tape drives
with the ASPI Manager.  The BIOS MUST be enabled to run hard
disks when using the ASPI Manager.

Up to four IN-2000 SCSI host adapter boards may be installed in
a system running the ASPI Manager.  Only the one set to the
lowest BIOS address will support hard disks.

The ASPI Manager requires that an interrupt channel on the
IN-2000 be enabled.  Switches 5, 6 and 7 select the interrupt 
channel.  Refer to the Installation Guide.

BIOS VCN:1-03 and later supports up to 7 SCSI hard drives 
under DOS 5.0 and 6.0 without the need for a loadable device 
driver.  Switch 8 = "ON" enables multiple drive support.  
See the IN-2000 Installation Guide for more information 
and/or check the ALWAYS BBS (818) 597-0275 for a BIOS update.

Make certain to load any caching software (SMARTDRIVE, VCACHE,
PC-KWIK etc.) after the ASPI Manager.  Most of these packages
work by hooking the disk interrupt (Int 13h), which is replaced
by the ASPI Manager.

Once the ASPI Manager is loaded DO NOT use any applications
which use the old IN-2000 SCSI Shell.  Such applications
include: Always' CD-ROM driver, NovaStor's NovaBack (ver 3.56D
and earlier), IN-2000 drivers (with BIOS enabled) and Always'
supplied Sytos PLUS drivers.  Both NovaBack and Sytos PLUS are
shipped with ASPI compatible tape drivers that work with the
IN-2000 ASPI Manager.  A CD-ROM driver will be released in the
near future that is compatible with ASPI.

DO NOT use the IN-2000 BIOS diagnostic or low level format
functions (from DEBUG) while the ASPI Manager is loaded.  To
perform diagnostics and/or to low level format a hard disk temp-
orarily remove the ASPI manager from CONFIG.SYS.

The ASPI Manager requires Hardware Revision 2.7 (An 8 pin
socketed chip) on the IN-2000 SCSI host adapter.  If you do not
have this Hardware Version, contact Technical Support for
upgrades (818) 597-1400.
