I immediately thank you all of the list who kindly answered all my questions when I first tried to install Crux with useful information. I registered and saved all the information given to use them at the appropriate time to do so.

However, I have decided to start from scratch and reinstall Crux- 3.1, because the error messages have become many and complex. This time I held the excitement with Crux and I made ​​no change in the contents of the installation media kernel. As a result, the installation went smooth and without errors . I got to the point of #ports -u and # prt -get sysup with no problem. The internet connection is perfect and the intel ethernet controller has been reconized at once. In the next step , I will go into graphics mode. 

I followed the guidance, by Don Cupp, that highlighted that the network connection should be created after a fresh installation of Crux. I expanded the guidance for all the other configuration itens without changing the contents of the installation media kernel. So, as very well advised by Don Cupp, I decided to "Follow the yellow brick road, follow follow follow, follow the yellow brick road.:)". This way, step by step, the installation has gone to the point I have mentioned above with success. I will return to the list with further questions. Cezar
