PS/2 MOUSE INTERFACE (OPTIONAL)
11.
The chipset of the MOPS/386A can support a PS/2 mouse. However, the standard
MOPS/386A is not equipped with this feature. A special version of this board can support
the PS/2 mouse feature. Such a version is only available upon request.
Connector
11.1
A PS/2 mouse interface is available on Connector X9 (4 pins), if the board supports the
feature.
An adapter cable is required to connect a standard PS/2 mouse. The cable is available from
Kontron (KAB-MOUSE-PS2, Part Number 96062-0000-00-0).
The following table shows the pinout and connections for a PS/2 mouse adapter.

To find the location of the PS/2 mouse connector on the MOPS/386A board, please see the
Appendix E: Connector Layout chapter.
Configuration
11.2
You can set the PS/2 mouse to enabled, disabled or autodetect from the BIOS Setup. If you
enable the mouse, the IRQ12 is used as the interrupt and is no longer available for other
devices. Please refer to the Advanced Menu in the Appendix B: BIOS chapter for additional
information on configuration.
Note: If the PS/2 mouse is enabled, the signal IRQ12 on the PC/104 bus connector is
connected to MSDAT. When enabling the PS/2 mouse, make sure that no external
device uses IRQ12.
