Detecting SoftICE ?

[Bruce Klein <bruce.klein () iovation com>]

Hello all,
 
I am writing a Win32 DLL and am currently trying to detect if SoftICE is present.
 
I am trying the "classic" detection methods and for my version of SoftICE (4.3.2) under Windows XP, so far no method 
has succeeded at detecting it.
 
The methods I am trying are well described in Viega & Messier's "Secure Programming Cookbook" and all over the net.  
One is the "Meltice" technique that looks for a virtual device named "\.\\NTICE"; the other uses the "Boundschecker" 
method that uses int 3, with "BCHK" 
in a register.
 
I am having no luck with either method. Perhaps because the methods are obsolete with the current version of SoftICE. 
Perhaps because I'm doing something stupid.
 
Given the above, I have two questions I'm hoping someone can answer:
    - Does anyone know a method to detect today's SoftICE?
    - Do the other methods even work (and for what versions)?
 
I'd be happy to post the small source or answer any further questions.
 
Thanks in advance.
