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

SDMS 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.

SDMS NT ASPI supports these features:

o  32-bit Windows applications 
o  Provides information about SCSI adapters and devices 
o  Use to issue SCSI I/O requests 
o  Multi-threaded and multi-tasking operations

SDMS 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. 

SDMS 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 ***************************** 

To install NT ASPI software, you execute an InstallShield setup program. 
If you obtained the software from the LSI Logic web site, it will be in the
form of a self-extracting zip file. Expand 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.
