Hello,everyone:<br>         I have built a parport server based on dde, and test it through on fiasco. Now I want to booting it together with l4linux, but there are conflict occured. <br>         And I have some questions to ask:<br>
        1. I used the l4linux-2.6.30 kernel, now to booting it besides fiasco default config, there is <br>                [ *] Enable I/O port protection<br>            feature must need, isn&#39;t it?<br>            It not needed in l4linux-2.6.23 kernel or earlier.<br>
        2. Will this feature prevent the other server to access to the io port?<br>            I seems meeting this problem, my parport server(#b) want to access the port 077a, but system say the owner is #a(l4io), even I set the parport priority higher than l4io, it also the same problem. the last error message is like follow:<br>
           ...............................  <br>           server  | &lt;6&gt;parport0: PC-style at 0x378 [PCSPP,TRISTATE]<br>           server  | &lt;6&gt;parport0: irq 7 detected<br>           ROOT: Cannot send port 077a to task #0b, owner is #a<br>
           ROOT: task B.00 at 01804299 is trying to get I/O port 077a allocated by task 0b.<br>           ................................<br>         How can I do could make the parport server run together with the l4linux, or to make it could access the port it needed?<br>
         Any help is precious.<br><br>         Best Regards!<br>         ding<br>
