Does anyone know of a good tutorial for installing a custom mouse handler for a PS/2 mouse? There are lots of examples of handlers using the serial mouse (and initialization with INT33h). But specifically how do I get the mouse data packets into a data structure (which can then be dealt with)? With a serial mouse it is easy (just check port address 0x3f8) but with a PS/2 mouse it seems that there is no I/O port address to check, just IRQ 12 ( which is mapped to hardware interrupt 0x74). Is there a port address for IRQ 12 ? Thanks in advance ... JAC
