CAUTION. In the following you find descriptions on how to change certain
parameters of the PC BIOS of the Protocol Tester if you are using a PC-3
board). Follow the instructions and do not change other parameters in the
PC BIOS as the device might become unusable or the performance might
degrade. If you have opened a menu that is not described here, press the
<ESC> key immediately in order to leave the menu.
If you want to switch off the trackball so that only the external mouse is
functional, you must change the PC BIOS.

the trackball on again):
1. Switch on the device. A blue framed screen appears with a title that
starts with:
Power Bios
2. Press <CTRL>+<ALT>+<ESC> as fast as possible.
A window appears titled Award Software International,
Inc. Power BIOS 1.00 Setup

PS/2 Mouse item is highlighted.
