INT 33 - MS MOUSE v6.26+ - GET SOFTWARE VERSION, MOUSE TYPE, AND IRQ(Interrupt ReQuest) A hardware line connected to the interrupt controller chip which signals that a CPU interrupt should be generated. NUMBER AX = 0024h BX = 0000h to check for function's existence Return: AX = FFFFh on error otherwise, BH = major version BL = minor version CH = type (1=bus, 2=serial, 3=InPort, 4=PS/2IBM PS/2, any model, 5=HP) CL = interrupt (0=PS/2IBM PS/2, any model, 2=IRQ2, 3=IRQ3,...,7=IRQ7,...,0Fh=IRQ15) Note: although current Microsoft documentation states that this function was introduced in v6.26, it appears to have been present as early as v6.02 (for earlier versions, use INT 33/AX=006Dh) SeeAlso: AX=004Dh,AX=006Dh
