Actually - I must confess to a little ignorance. I could not remember
all of the  'printf'  syntax options. Id id not seem to have any man 
pages
(under beos), and I had no prior experience with the gnu compilers.
Not all of the compilers I have worked with supported %lu.

I added a third parameter  "int array_limit"  to the sort_addr_range()
function.  The function was called with the  define macro
MAX_PHYSICAL_ALLOCATED_RANGE providing this third parameter.

Inside the function - I was trying something like  dprintf(" ... %d\n", 
array_limit );
Whatever the type of a define works

The define had a value of  4.  But I was seeing anything but 4 being 
printed.

Could you identify a code module where I could start my investigations
regarding recognizing the CPU's ?
I am all eager to try and get the maximum out of my machine.
