Dear All:
Here is the newest version . It fixed some kernel code bug. Please using it for replacing old version. I come back on. I have a gift for sharing all members. I writed a tool and it's used for removing I/O protection on Win32 Platform. Then you will feedom using any program accessing I/O ports. The IOCRACK will modify the I/O permission bitmap to allow a particular task, access to certain I/O ports. This grants your usermode program running in ring 3 to do unrestricted I/O operations on selected ports, per the I/O permission bitmap. This method is not really recommended, but provides a means of allowing existing applications to run under windows NT/2000. Writing a device driver to support your hardware is the preferred method. The IOCRACK.EXE provides the facility to modify the IO permission bitmap and/or write and read to I/O ports via IOCTL calls. The application will acessing freedomly I/O Ports under Win9X/NT/2000/XP/Win2003 through IOCRACK. It's only for executing one and removed the I/O port protection. File Description: iocrack.exe :Main Program readme.txt :Function Description The tool's version is 1.02. It's writed by pure FASM laguage on one week. If you have found any bugs about it, Please talked me. Thank you.

now I have XP and 2000 and it is a very good tool for me,
but when I had w98 I remember that the direct acces to IO_ports like BIOS KEYBOARD or LPT ports wasn't protected. regards _________________ Microsoft: brings power of yesterday to computers of today. |

Hi,HarryTuttle:
The tool will removing IO port protection on win32 platform. In the win98.You can't access some ports:IDE ports,etc. The tool will freedom all of IO ports. So the OS can't protect it. |

Hi,GuyonAsm:
Yes. The OS will poping an error diaglog and talked me your application accessed invalid I/O port. The win32 required the accessing IO ports of behaior must be through driver . So I writed the tool for helpping application on ring3 freedomly accessing I/O ports. And others, Can you tell me the test result on your machine? Because the tool is OS kernel tool. I haven't test it on all of platforms. I uploaded the newest package. Please using it. Hi,scientica : Please helpping me to delete my attached package on the http://board.flatassembler.net/topic.php?t=520 The missy111 is awful and I don't like my program on him post. Thanks. |

Done.
Btw, I think it executed correct, for about a second the system froze with the beeper making noise, then this popup: Quote: Creacked I/O Port Protection is sucessful! The machine I tested it on runns Win2k Pro SP4. _________________ ... a professor saying: "use this proprietary software to learn computer science" is the same as English professor handing you a copy of Shakespeare and saying: "use this book to learn Shakespeare without opening the book itself. - Bradley Kuhn |
