I want to use my ms-mouse on the non-standard com3 or com4.
My ports use irq 10&11 and I have tried to debug and change some 
of the IN's and OUT's in the mouse-driver without success.

I have found where to patch the i/o-address ,it is not difficult
to patch and get it to work as long as the irq is in the first
interrupt-controller. To use the second interrupt-controller
the port-addresses should be changed from H'20&H'21 to H'A0&H'A1 ??
But its to many calls to the controller in the code so the
trial and error way seems to long.

Is there some info in the SDK-kit for windows about the mouse-driver ?
Maybee someone has the sourcecode or the assembler listing ?

All hints where the correct addresses are is welcomed
