There is always lots and lots of documentation. To have time to go through all of it is usually impossible, not to mention confusing and discouraging when you are looking for something specific. To get proper steering at the beginning makes all the difference. Thanks again. Now I can maybe come back with more specific questions, or better yet, not come back at all (i.e. mission accomplished!). Since this channel is not too noisy, I think I will post back with more complete method and results once I get there. /jfd -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
