Int 32 Fn 6E12 - Noise.sys V0.53+ - Add Sample From Fast Timer [y]
AX = 6E12h
Return: CF set on error
AL = error code (FCh,FDh,FEh) (see #2837)
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).
