	    AH = 00h (SMBus(System Management Bus) A derivative of the I2C bus used for communication between various components of a computer, such as smart batteries and their chargers.  In contrast to I2C, SMBus specifies fixed voltage levels (instead of relative to the power supply voltage) and a 10 KHz minimum clock rate (I2C minimum is 0).  SMBus also specifies several timings which are not required by I2C.  See also I2C, ACCESS.bus. OK)
	CF set if error
	    AH = error code (03h,04h,05h,0Ah,86h) (see #00484)
