Virtual ASPI driver (VASPI.SYS) BETA release #1 (12/13/93).
The ASPI support currently embedded within OS/2 2.1 allows any OS/2
application to send commands to a SCSI device. However there are
a large number of DOS and Windows applications that are could be
supported if there commands were routed to OS2ASPI.DMD
VASPI.SYS is a virtual device driver that will allow DOS applications
to issue SCSI commands that will be handled by OS2ASPI.DMD. If you
have an existing DOS ASPI application it should now be able to run
in a virtual DOS session under OS/2 2.1.
**** NOTE ****
There is currently NO support for the ASPI for Windows specification
that uses WINASPI.DLL as its primary interface. Support for these
applications may be added in the future, but until then only
Windows applications that support the DOS interface should be tested.
1) Install OS/2 2.1 on your system
2) Make a backup copy of the file OS2ASPI.DMD. This should be found
in the \OS2 directory on your boot drive.
3) Copy the new VDD aware version of OS2ASPI.DMD into the \OS2 directory.
4) Copy the file VASPI.SYS into the directory \OS2\MDOS on your boot drive.
5) Update CONFIG.SYS as follows:
a) Make sure the line BASEDEV=OS2ASPI.DMD is present somewhere
in the file.
b) Add the line DEVICE=C:\OS2\MDOS\VASPI.SYS to the bottom of
the file. If your boot drive is NOT C:, use the appropriate
6) Shutdown your system and reboot.
7) Open a DOS window or DOS fullscreen and run your ASPI application.
