Ho do I get the hard disk serial number / or volume serial number using in win3.11. In win95 it is possible to use the GetVolumeInfo() API, but not for win3.11. Is the serial number in RAM, and if so where is it. Is it possible to write some in line assembley code to do fetch it.

Thanks

It is you code in C++(not Assembler):
void FindDiskName(char *szNameDisk)
{
  struct SREGS sregs;
  union  REGS regs;
  char   szTemp[512];
  int    block[5];
                              //clear all
  memset(&sregs , 0, sizeof(sregs));
  memset(&regs , 0, sizeof(regs));
  memset(szTemp , 0, sizeof(szTemp));
  memset(block, 0, sizeof(block));

  memset(szNameDisk, 0, sizeof(szNameDisk));

  block[2] = 1;
  block[3] =  FP_OFF(szTemp);
  block[4] =  FP_SEG(szTemp);

  sregs.ds = FP_SEG(block);
  regs.x.bx = FP_OFF(block);
//                     absread(as Interruption, vers 4.0 and //more)
  regs.h.al = 0x02;                  //disk C
  regs.x.cx = -1;                  //data in block
  regs.x.dx = 0;                  //1-st Sector

  int86x(0x25, &regs, &regs, &sregs);      //read
  if (regs.h.ah == 0)                  //ok?
    {
      for (int i = 42, j=0; j < 4; i--, j++)
      CtoStr(*(szTemp+i), szNameDisk + 2*j);
      szNameDisk[8] = '-';                  //form name
    }
}
static char *szDigit = "0123456789ABCDEF";
void CtoStr(char c , char *str)
{
   str[0] = szDigit [ (c>>4) & 0x0F];
   str[1] = szDigit[(c&0x0F)];
}

Thankyou Alex for your help, I guess this code will work for all platforms as well. e.i. win3.11, win95, winNT..

Thanks
