[NBLUG/talk] UEFI and CentOS installer boot parameters

[Omar Eljumaily]

Which version of Centos are you using?  UEFI seems to be well supported 
in 7, but marginally in other versions.

Booting seems to be getting harder and harder these days.  I got a very 
popular MB from Amazon and had big problems with a fresh install of the 
latest Ubuntu LTS.

Also switching from one motherboard to another used to be very 
straightforward, and now it's very tricky.  I always thought it was a 
benefit of Linux.  When Windows got temperamental about switching Mobos, 
Linux wouldn't.  But now that seems to have changed, at least for the 
technology, but not DRM.
