Detecting Windows NT from an MS-DOS-Based Application
Article ID: Q100290

...

Interrupt 21h, function 3306h can be used by MS-DOS-based applications to
detect whether or not they are running under Windows NT. On return, registers BL
and BH will contain the operating system major and minor numbers, respectively.
If your application is running under Windows NT, the return will be:


   BL = 5
   BH = 50

Note that it is important to check both BL and BH, because MS-DOS 5.0 will also
return a 5 in BL.

The following code demonstrates how to detect the operating system version from
an MS-DOS-based application:


Sample Code


#include <stdio.h> #include <stdlib.h> #include <io.h>

void main() {

   unsigned char cbh = 0;
   unsigned char cbl = 0;

   _asm {
      mov ax, 3306h
      int 21h
      mov cbh, bh
      mov cbl, bl
   }
   printf( "After int 21h\n" );
   printf( "%u, %u (bh, bl)\n", cbh, cbl );

}

Довольно древняя статья, но, думаю, должно работать.


Пока!
Andrey
