2.8 Hot plugging the ADDERview into running systems and
re-enabling disconnected CPU PS/2 mouse connections
It is adviseable to switch off the systems that are going to be connected to the
ADDERview before installation. However if this is not possible then most systems
can be hot plugged by using the ADDERview’s mouse restoration functions. The
keyboard connection will normally restore itself automatically.
On many PCs, mouse movement will be lost if the PS/2 mouse is unplugged and
plugged back in whilst the PC is running. Mouse movement can then only be
restored by rebooting the PC. This is because the mouse drivers only setup and
enable the mouse when the PC is initially booted.
If you have switched off or reset your ADDERview or you are attempting to ‘hot plug’
it into a system that is already running, you may be able to restore lost mouse
movement using the ADDERview's mouse restoration functions.
Mouse restoration functions should be used with care as unpredictable results may
occur if the wrong mouse type is selected. If in doubt restore the mouse by powering
down the PC normally.
Standard PS/2 mouse data uses a different data format to IntelliMouse data and so
two reset functions are provided on the ADDERview. The type of data format
expected by the PC depends upon the driver and the type of mouse that was
connected when the driver was booted. The following table may be used as a guide.
Note that the mouse reset functions predict the likely mouse resolution settings but
may not restore the speed or sensitivity of the mouse exactly as they were when the
PC originally booted.
