[ ] Enable I/O port protection If you enable this option only kernel has full access to all I/O ports. As a result when l4lx could access some resources it has no enough rights. So there is "bad permission" or "permission denied" message. So If you run l4linux disenble this option. It is my opinin. You can try. Thanks cheng

Sorry for the last e-mail I accidently pushed sent button.. The content of the bin folder doesn't contain 'isocreator' executable. And I am stuck in creating iso . I have tried to create iso with mkisofs but I could not succeed. Also I couldn't find dmon in the svn repos. Could you give the exact repo address for dmon so I can check it out.

Lets call it iso 2. in the iso directory create a boot/grub directory 3. put the files you want to boot somewhere into the iso directory (preferably into boot/) 4. create the respective Grub entries in boot/grub/menu.lst (have a look at the demo-cd boot/grub/menu.lst for examples) 5. in the iso directory, call '$(L4DIR)/tool/bin/isocreator . image' 6. boot the image with 'qemu -serial stdio -cdrom image' You might want to check which VBE modes qemu supports. The option -serial stdio gives you the serial console in the terminal window where you started qemu. > Do you mean RS232 cable serial null modem cable? I am working L4 on laptop therefore I don't have a direct RS232 access. I can not maintain that logs now. Are there any other ways that can I collect that this log info? As an alternative you can obtain the package dmon from our SVN repository (if you do not have it already). In the dmon directory is a README how to use it. Dmon basically opens a dope window and collects all debug logging information. This way you can see the log output even if you do not have a serial null modem cable and a second computer to debug. On the downside you will have to copy the debug information by hand (write it down, type it into your email program...).
