Take a look at :
http://www.sysinternals.com/ntdll.htm
They say these native API are documented in WinNT DDK documentation.

Already looked there, you will notice that it says that only 25 of the calls are documented in the DDK.  My question is how do I get the parameters for the *undocumented* calls.

Trial and error along with stepping through the functions with a debugger (like SoftICE) is the only way to learn about what is going on in the undocumented functions.
