The new Kithara »DOS Enabler«

Now available: 16-bit programs in real-time on a 32/64-bit Windows system

The »DOS Enabler« enables hardware-dependent DOS programs for several years now. The new »DOS Enabler« also supports Windows 7, 8/8.1 or 10 with 32 bit or 64 bit!

Notice: For the development of new hardware-dependent and time-critical 32-bit and 64-bit applications see »RealTime Suite«.

The new »DOS Enabler« enables hardware-dependent DOS and 16-bit Windows programs to work under Windows 7, 8/8.1 or 10. The software supports 32-bit and 64-bit systems. The new »DOS Enabler« has its own DOS system (FreeDOS) and performs the 16-bit applications natively on a separate CPU core. By elimination of any side-effects Windows, time-critical applications are possible.

The program execution including hardware access to I/O registers and physical memory as well as the handling of interrupts is done in real-time.

Same as before, but a 1000 times faster!

Features of the new »DOS Enabler«

  • Usage of a separate CPU core without being interrupted by the Windows multi-tasking
  • Full allocation of processing power to the DOS program, so that time-critical routines run without restriction
  • Direct and undelayed access to physical I/O registers
  • Direct access to physical memory between C000:0000 and E000:FFFF
  • Handling of hardware interrupts
  • 16-bit applications are executable under Windows 7/8/8.1/10 as well as Embedded 7/8 (32-Bit/64-bit)
  • No virtualization environment necessary!
  • COM ports can be redirected, e.g. to USB ports, PCMCIA cards, PCI boards, virtual COM ports
  • Intelligent buffering for avoiding loss of data

New with Version 9.61

  • DOS applications are able to access separate drives such as USB sticks (FAT and FAT 32 are supported)
  • new command line option allows for the automatic startup of the DOS Enabler including a DOS program, e.g. for the starting via desktop icon or autorun registry entry
  • on the DOS side a batch can be used to close the DOS Enabler or to shut down the PC
  • improved real-time performance

New with Version 9.62

  • 4 MB extended memory can be used
  • support of ISA-BUS devices
  • improved keycode translation
