The HILMOU.SYS and NOEXBIOS.SYS are the drivers that support 
the HP-HIL mouse for IBM OS/2 2.0.  To install the drivers, 
first copy them to the \OS2 directory of your boot drive, 
then make sure the following lines are in CONFIG.SYS (change 
lines or add to existing lines):

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

where x is the boot drive letter (usually c).

The MOUSEHP.SYS is thed driver that supports the HP-HIL mouse
for IBM DOS 5.0.  To install the driver, first copy it to the
\DOS directory of your boot drive, then make sure the following
line is in CONFIG.SYS (change lines or add to existing lines):

  device=x:\dos\mousehp.sys /y

where x is the boot drive letter (usually c).
