******************** Introduction for Window NT 4.x ******************** 

Symbios Logic NT ASPI for Win32 is a software support package based on the 
"ASPI for Win32", version 2.0 specification.  The ASPI software provides
a mechanism used by Win32 applications as an interface to access SCSI 
adapters and peripherals.

Symbios Logic NT ASPI for Win32 is designed to the Advanced SCSI Programming
Interface (ASPI) version 2.0.  Win32 applications use this interface to gain 
access to system SCSI devices.  Applications using this interface can retrieve
information about installed SCSI adapters and the SCSI peripherals attached to 
the adapters.  Applications using the ASPI interface can issue SCSI I/O
requests to the devices.  Typical of these type of applications are utility
programs that investigate and explore SCSI devices, or, applications such as
CD-R mastering software and scanner applications.

Symbios Logic NT ASPI for Win32 is comprised of two modules: a user mode DLL,
and a kernel mode device driver.  Applications using ASPI only interface with
the user mode DLL.  The DLL passes commands and requests to the kernel mode
device driver, which in turn interfaces with the NT operating system for
execution of the request.


*********************** Installing NT ASPI for Win32 ********************* 

*  *  *  *  *  *  *  * Preparing a Symbios Driver Diskette *  *  *  *  *  * 

The NT ASPI for Win32 software is installed by executing an InstallShield 
setup program.  If you obtained the software from the Symbios Logic BBS or
FTP site, it will be in the form of a self-extracting zip file.  You can
install the software by expanding the zip file into a directory on your
hard disk drive, or to a diskette and then run "setup".  If you receive the
NT ASPI files on a diskette, simply run "setup".

The setup program will install the NT ASPI files into the proper directories
as well as making the appropriate registry entries.

After installing the software, you must reboot the computer.
