models which are equivalent to the ones listed above are also eligible
for this patch if the Mwave software from the OS/2 Warp 4.0 Device Driver
Pack (CD) is in use.

Installation Procedure
----------------------

Assuming that the driver letter which contains your Mwave OS/2 support is
C and the base directory is MWAVEOS2, you may use the following steps to
apply this patch.  If your drive letter or base directory is different,
simply substitute your letter or directory in the appropriate places.

  RENAME C:\MWAVEOS2\BIN\MWAVEVDD.SYS *.BAK
  COPY MWAVEVDD.SYS C:\MWAVEOS2\BIN

When doing this, you may need to provide a path to the new copy of
MWAVEVDD.SYS for the COPY command if the new copy is not in your current
directory.  For example, if the file is on a diskette in your A drive,
you would need to do the following.

  COPY A:\MWAVEVDD.SYS C:\MWAVEOS2\BIN

When the RENAME and COPY commands have been completed, shutdown OS/2 and
restart OS/2 to make the patch take effect.
