Ned,

The USB ethernet adapter was a good thought, but removing it did not
make a difference.  I removed the adapter, rebooted with same failure,
then manually turned off system and did a boot with the adapter
unplugged, then did another reboot which had the same failure.  It does
not look like the adapter is the problem. 

I will take another look at the Gateway website.  First search attempt
did not result in anything productive, that is why I looked at the
American Megatrends site which had a bios download tool, but it was for
a windows machine.  I am going to continue to look, I think my best
choice would be to take another look at Gateway site.

This machine worked perfectly under CentOS 6, I can still use it with
CentOS 7, but it is a real pain to reboot.
