JTAG Flash Loader

To get it running under WinNT/2000/XP a special kernel driver is needed.
These systems do not allow direct access to I/O ports.

Just copy the file UserPort.sys into (for example) c:\winnt\system32\drivers 
and run the program UserPort.exe
(by double-clicking the icon - it's a Windows program).

Click on 'Start' and then 'Exit'. If you ever wish to remove 
the kernel driver start the program again and click 'Stop'.

Under Win95/98/Me all this is not needed!
