INT 32 - NOISE.SYS v0.53+ - ADD SAMPLE FROM FAST TIMER

	AX = 6E12h
Return: CF set on error
	    AL = error code (FCh,FDh,FEh) (see #03166)
	CF clear if successful
	    CX = number of random bytes waiting
Note:	subfunctions 12h and 13h are meant for applications or devices
	  which are able to gather entropy from other sources which are
	  not polled by NOISE.SYS (for example, a communications driver
	  could use this call to sample packet arrival times).
