Introduction

The generic MPU-401 Device Driver is for MIDI interfaces in AT compatible
systems with an ISA bus.  It was written under OS/2 1.21, and has been
tested under 1.21, 1.3, 2.0, and 2.1(beta).

The device driver supports the complete set of MPU commands.  Extensions
specific to OS/2 have been added, and are available through the DMS MPU
Interface Library.  If you are interested in purchasing the library, please
use the order form (see the file ORDER.FRM).

This software is not in the public domain; however, it may be distributed
freely so long as it is not bundled with any commercial product, or any fee
beyond duplication and shipping is charged for distribution.  If you would

Installation

To install the device driver, copy the MPU401.SYS file to your \OS2 directory.
Edit your CONFIG.SYS file, adding the line

DEVICE=C:\OS2\MPU401.SYS

If you find a line DEVICE=C:\OS2\COM01.SYS in your CONFIG.SYS, add the 
MPU
statement before the COM line.  Otherwise, location is of no relevance.

If you are using the default port and interrupts (Port 330 and Interrupt 9),
you are finished.  Save the file and reboot your computer to complete the
installation.

If your interface is not configured for the default port or interrupt, add
one or both of the following parameters

Port
    /Pppp  -  where ppp is the port location.
              e.g.  for port 310:
              DEVICE=C:\OS2\MPU401.SYS /P310


Interrupt
    /Inn   -  where nn is the interrupt used.
              e.g.  for interrupt 5:
              DEVICE=C:\OS2\MPU401.SYS /I5

Both
              e.g.  /P310 /I5
              DEVICE=C:\OS2\MPU401.SYS /P310 /I5


After making the necessary changes, save the file and reboot your computer.

When the system is rebooted, you will see (albeit briefly) a message from
the device driver giving copyright and version information, as well as the
port and interrupt values.  If an error occurs, the booting process will
pause.  Check the error message, and hit F1 to continue the boot.  The
MPU device driver will not install if any errors are detected.  Correct the
errors and reboot.

Note for ADAPTEC SCSI Interface users:  Some Adaptec SCSI controllers use
port 330, which is also the default for the MPU cards.  We recommend
that you change the port on your MPU card, and add the /P statement shown
above.


Installation Check list
=======================

___  Install the interface according to the manufacturer's instructions.


___  Install OS/2


___  Copy the MPU401.SYS file from the installation disk to the C:\OS2
     directory.


___  When OS/2 is installed and running, edit the CONFIG.SYS file (You can
     use the system editor in the MAIN program group), and add the
     DEVICE = C:\OS2\MPU401.SYS line as shown above.  Don't forget to save
     the file.


___  Shutdown OS/2 from the Desktop Manager Group.  When the system is
     completely shut down, reboot the computer.


___  Watch the screen during boot-up to verify the correct installation
     of the device driver.  When the driver is loaded, it will display a
     message indicating the port and interrupt being used.
