If you get the Ralph Brown's Interrupt List (from http://www.cs.cmu.edu/afs/cs/user/ralf/pub/WWW/files.html), you can find also the list of ports there inside - I've been using when doing OS programming and it's really good.

It's generally a bad idea to go bashing ports unless you have a specific reason for it (ie, keyboard handler for a game, or drivers for an OS). If there's DOS or BIOS calls and they work, it's better to use them, as your code will be more likely to work everywhere (various DOS versions, v86 environments under various OSes, boch, dosbox, ...)

I had some troble finding it in all those files, but I finally found it in http://www.cs.cmu.edu/~ralf/interrupt-list/inter61d.zip Thanks Tomasz
yes f0dder I know, and it can be really dangerous coz I guess if used wrong, the in instruction can burn something in the computer ..  |

For direct port I/O on NT, forget the above link from The_Grey_Beast and have a look at this:
