JSI Tip 0900. My mouse wheel is not detected.

If you have a PS/2 Wheel Mouse without special driver (IntelliPoint or 3rd party), and the wheel is not functional, it is probably not being detected. Browse to:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\i8042prt\Parameters

Edit or Add Value name EnableWheelDetection, a type REG_DWORD, and set the data to 2.

You can set the scroll by using tip 145.

Restart your computer.

 Value   D e s c r i p t i o n 
 0   Don't use the wheel. 
 1   Auto-detect the wheel. 
 2   Always enable the wheel.
