Microsoft Windows NT 3.51 Or 4.0
Installing the mouse driver

Procedure:

1.   Copy the files in the directory of the default HP build
  of Windows 95 or Windows for Workgroups
  C:\OMNIBOOK\DRIVERS\NT\MOUSE to a 3.5 floppy disk.

2.   Boot up Windows NT as you normally would.  Insert
  the 3.5 floppy disk with the mouse driver files into the HP
  OmniBook 800 floppy disk drive.  Create a new directory
  called ‘mouse’ on the root of the C: drive.  Copy the files
  on the floppy disk drive to the mouse directory.

3.   Double click on setupamc.exe.

4.   Reboot the HP OmniBook 800.  The correct mouse driver
  will now function correctly.
