I am trying to include code in my C program that will report the
amount of memory on a computer (Conventional, EMS, Extended).
I can use the Turbo C built-in function biosmemory() to get 
conventional memory.  I am having trouble with extended
memory.  I am trying to use BIOS INT 15 Function 88 for this.

The relevant subsection of my code is as follows:

	union REGS regs;

	basemem = biosmemory();    // reports 640K 

	_AH = 0x88;
	int86(0x15, &regs, &regs);
	cout << "Extended memory: " << _AX << endl;

My system has 7168K extended memory.  However, when I run the
code above it prints out "Extended memory: 34368".  According to
the documention I have, _AX should contain the number of K of
extended memory as reported by POST.  Thus I would expect, 
to see "7168" in AX.  Am I missing some conversion or something in 
there?

Thanks in advance for your help.
