For OS/2 2.0, 2.01, 2.1, and 2.11, omit the settings that are not 
present in those versions.  You should not need to change any other 
settings. 

Additionally, if you have DOS version 5.0 or above, you may find a 
substantial performance increase if you create a virtual secession 
running the actual copy of DOS.  Creating a VMDISK is relatively easy, 
and complete instructions can be found on-line by typing 'HELP VMDISK' 
in an OS/2 window.

NOTE : OS/2 is not an officially supported environment for Wing
Commander III.  These settings are suggestions only. While they should
work for you, Origin's Technical Support is not as knowledgeable at
resolving OS/2 difficulties as IBM. Origin recommends you contact IBM 
Technical Support for a resolution.

Good Luck!!!
