The reason for my last question is that I want to run and test some microcode on the ixp1200 without the rest of the ACE environment. I would also like to have the option of not using ACEs when our code is ready to be put on the IXP1200. To do so I need to get a .uof running on the microengine. Ideally, I'll write and debug in the workbench, then when it comes time to deploy I take the .uof's I got from the workbench and start them with the code I'm trying to write now. Is this direct/ACEless approach possible? Najati
