Re-Enabling A Disconnected Ps/2 Mouse; Hot Plugging The Adderview Mp Into Running Systems And Re-Enabling Disconnected Ps/2 Cpu Mouse Connections - ADDER AVMP4-SP Installation And Use Manual

2.10 Re-enabling a disconnected PS/2 mouse

If you disconnect the shared PS/2 mouse from the AdderView MP by accident
during operation then the mouse operation will be lost when the mouse is plugged
back in. To avoid having to reboot the entire system in this situation the AdderView
MP is fitted with an automatic mouse recovery system.
With the PS/2 mouse disconnected, change the channel using the keypad or
keyboard hotkeys. The AdderView MP detects that the mouse has been
disconnected and triggers the automatic recovery system. Plug in the PS/2 mouse
and the AdderView MP will re-initialise it.
2.11 Hot plugging the AdderView MP into running systems and re-
enabling disconnected CPU PS/2 mouse connections
It is advisable to switch off the systems that are going to be connected to the
AdderView MP before installation. However, if this is not possible then most systems
can be hot plugged by using the AdderView MP'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 your AdderView MP 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 MP'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 MP. 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
