To all those who have gratiously assisted with my Inel integrated network interface controller problem:
I have bitten the bullet and installed a NIC card from Trendnet. I am not promoting this product. Only that it solved my problem at a reasonable price. Someone previously suggested this step. I have finally taken it.
I was confused by "device was working properly', although "software has not been installed". I have finally realized the difference. This Dell Dimension 5150 was designated as my "learning" computer; I have certainly learned much from this experience, mostly due to your input. I hope to continue my lesrning process.
Internet conection works well now.
Even the floppy drive is functional, as well as the 10GB HD from my first ever computer.
Grats again to all who asisted.
