INT 32 - NOISE.SYS v0.53+ - GET ENTROPY ESTIMATE

	AX = 6E11h
Return: CF set on error
	    AL = error code (00h,FDh,FEh) (see #03166)
	CF clear if successful
	    EBX = estimated bit count (refer to note below)
	    CL = FRACBITS (number of fractional bits)
	    EDX = low 32-bits of total number of samples added
Note:  the estimated number of fresh random bits is equal to
	  (EAX >> FRACBITS) + ((EAX & ((1 << FRACBITS)-1) / (1 << FRACBITS))
