Thank you Ken, that is helpful information. You are right, the contents of the firmware directory did not give me what I wanted, but I did find the correct firmware and install it. It's looking good now. Now, on to X! -- http://lists.linuxfromscratch.org/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
