The regular installer we released for CentOS-6.3 does not work for UEFI
enabled machine instances that do not have a BIOS fallback mode ( this
includes physical machines as well as some virtualised environments ).
To address this problem, we are releasing another minimal install image
for CentOS-6.3/x86_64. This image has been tested on various IBM, HP and
Dell hardware along with VMWare and VirtualBox virtualisation products.
If you are unable to verify the image using sha256, you can also get
other checkums :
md5 : http://mirror.centos.org/centos/6/isos/x86_64/md5sum.txt.asc
I'm trying to make sure that we do enough testing and have enough
resources for UEFI testing to ensure that the next and subsequent
releases do not have a problem in this environment. In the mean time,
the installer buildsystem for CentOS-6 has been updated to also build
and test the UEFI requirements in sync with the rest of the installer
Thanks to the guys at VMware for working through this issue with us. As
well as Christoph Galuschka and Pasi Kärkkäinen from the CentOS QA team
for helping test this image.
Feedback is welcome via either the issue tracker or the centos-devel
list. And we are always looking for more people to come and join the
testing effort, specially on platforms and environments we dont have
exposure to at the moment. Want to help on that front ? Drop in on
#centos-devel on irc.freenode.net and say hi.
