How to get the PIII processor serial number (psn) in Intel format

Sample Image - maximum width is 600 pixels

Introduction

Many programmers always ask how to make their program run on a single computer. This code is one way for that and it gets the serial number in Intel format.

Background

To understand the code you need to know some assembly and the cpuid instruction and how it works. You can get more information from www.intel.com

Using the code

To use the code simply paste this function to your class dialog

Programmer:haitham hamed housin
description: get the PIII processor serial number (psn) like intel format
USE:to restrict your programs to run on single computer
classification: security 
demand: i need information about P4 PSN i can't belive that they ignore it

need more information contact me

void CPiiisnDlg::GetProcessorSeialNumbet(bool withSeparator)
{
DWORD  t,m,b; //top,middle,botttom
DWORD* serial;
  _asm
  {
    mov   eax,1 //programmer: I need a Service ?
         //processor: what type baby?
      //eax = 3 --> 
       //eax: top 32 bits are the processor signature bits
         

       //programmer:this
    cpuid     //_emit 0x0f |cpuid mean this tow instruction
          //_emit 0xa2 |instead of writing them 
       //       
    //mean:the sevice i want the processor serial number

 mov   t,eax // top 32 bits are the processor signature bits
           /* 
          eax = 3 --> 
        ecx: middle 32 bits are the processor signature bits
         edx: bottom 32 bits are the processor signature bits
      */
    mov   eax,3
    cpuid
    mov   m,edx// middle 32 bits are the processor signature bits
    mov   b,ecx// bottom 32 bits are the processor signature bits
  }

  // copy the locals into the pointer variables passed in
  serial[0] = b;
  serial[1] = m;
  serial[2] = t;


CString temp;
m_SN.Empty();
static char hex_chars[16] = {'0','1','2','3','4','5','6','7',
                 '8','9','A','B','C','D','E','F'};
for (int dw_count = 2; dw_count>=0; dw_count--)
  {
    for (int bp=28; bp>=0; bp-=4)
    {
      DWORD nibble = (serial[dw_count] >> bp) & 0x0f;
      temp.Format("%c", hex_chars[nibble]);
   m_SN+=temp;
      if ((bp == 16) || ((bp == 0) && (dw_count!=0)) )
    if(withSeparator)m_SN+="-";
    }
  }
UpdateData(FALSE);
}

Points of Interest

I can't believe that P4 has no sn and if any one knows any thing on that please contact me.
