Notes:	this port can only be accessed via 8-bit IN or OUT instructions by
	  the CPU(Central Processing Unit) The microprocessor which executes programs on your computer.
	supported by the Intel "Saturn" and "Neptune" (82434NX) chipsets,
	  the Intel 82454KX/GX (450GX chipset), Intel 82420EX chipset, etc.

	0 soft reset
	1 hard reset
 0	deturbo mode
Note:	when resetting the CPU(Central Processing Unit) The microprocessor which executes programs on your computer., two writes are required: the first sets the
	  state of bit 1 while keeping bit 2 cleared, and the second sets
	  bit 2; the reset occurs on bit 2's transition from 0 to 1.
