	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/2, 5=HP)
	    CL = interrupt (0=PS/2, 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)
