Whew!  Now let's get to the fun part.

First, install OS/2 2.0 and select the PS/2 mouse option. You should
get the following lines in config.sys...

  device=c:\os2\pmdd.sys
  device=c:\os2\mdos\vmouse.sys
  device=c:\os2\pointdd.sys
  device=c:\os2\mouse.sys

Copy noexbios.sys and hilmou.sys to the appropriate directory. In this
example, it is the root but you can use whatever directory you want.
Edit the config.sys file so it looks like...

  device=c:\os2\pmdd.sys
  device=c:\os2\mdos\vmouse.sys
  device=c:\os2\pointdd.sys
  device=\noexbios.sys
  device=\hilmou.sys
  device=c:\os2\mouse.sys type=hilmou$

Reboot the system.
