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

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

Symbios NT ASPI is designed to the Advanced SCSI Programming Interface (ASPI)
version 2.0 specification. All Windows 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 types of applications are utility programs that investigate and
explore SCSI devices, or applications such as CD-R mastering software and scanner
applications. 

Symbios NT ASPI is comprised of two modules: 

1.  a user mode DLL, and 
2.  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 Windows NT operating system for execution of the request. 


****************************** Installing NT ASPI **************************** 

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

NT ASPI software is installed by executing an InstallShield setup program. 
If you obtained the software from the Symbios BBS or Web site, it will be in the
form of a self-extracting zip file. 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 installs 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.
