 --[ Description ]-------------------------------------------------------
  
        Says the DOS type and version.

 --[ History ] ----------------------------------------------------------
	
        0.00: Original file by Natalia Portillo. No DOS type.
        0.01: Tested with following DOSes obtaining:
              DOS             DOS Version     DOS OEM Code
              DR-DOS 7.03     6.0             0x00
              FreeDOS Beta 4  6.22            0xFD
              MS-DOS 3.20     3.20            0x00
              MS-DOS 3.30     3.30            0x00
              MS-DOS 4.01     4.0             0xFF
              MS-DOS 5.00     5.0             0xFF
              PC-DOS 3.30     3.30            0x00
              Windows 98 S.E. 7.10            0xFF
              Windows 2000    5.0             0xFF
        0.02: Tested with the following DOSes obtaining:
              DOS             DOS Version     DOS OEM Code
              PTS-DOS 2000    6.22            0x66
              RxDOS 7.1.5     7.0             0x5E
        0.03: Almost remade from zero.
              Now uses four functions of INT-21h to get almost all
              DOS version information.
              All detect stuff moved to int21h.c.
              All defines moved to ver.h
        0.04: Implemented detection of DESQview, 4DOS and NDOS.
              Implemented detection of the Windows version.
              Implemented detection of OS/2.
              Implemented detection of Windows Millenium (tested with beta 3).
