2.9.17 PS/2 keyboard/mouse
Slot for a standard PS/2 mouse or a PS/2 AT-Enhanced keyboard. BIOS automatically
determines whether a mouse or a keyboard has been connected, and transfers this information
to the operating system.
With a PS/2 Y-cable, both keyboard and mouse can be operated simultaneously. They must be
connected before the system is switched on.
This interface has a Hot-Plug function for PS/2 keyboards (only when no PS/2 mouse has ever
been connected and used!).

Warning!
Because of general PC specifications, this interface should be used with extreme
care concerning EMC, location of cables, etc.. It should therefore only be used for
service!
Information:
The BIOS setup defaults only allow for the operation of a PS/2 keyboard. If a PS/2
mouse is connected, it must be activated in BIOS. In order to do this, set "PS/2
mouse" in the BIOS setup menu to "enabled" and save. (Located under Advanced -
Miscellaneous - Item "PS/2 mouse").
