Sorry for so much quoted text, but I needed context.  The new mobo is 
here and will only boot into Maintenance Mode, with no network access. 
Attempts to move to a full text boot fail.  I'll try to remove both 
kmod-nvidia and akmod-nvidia, but I don't know if yum will do that 
off-line.  If not, what next?
