In order to install MOR, you need the Centos 6 system (Install newest CentOS 6 version).

First of all, you need to download the Install image. Decide which architecture you need (i386 or x86_64) and download minimal iso, because necessary to install only the base system.

How do you choose between i386 (32bit) and x86_64 (64bit)? There is a simple rule: if you have 4gb of RAM or more, choose x86_64 (64bit).

Centos can be downloaded from here: http://mirror.centos.org/centos/6/isos/ (we recommend downloading latest releases).

As an example, for i386 you should download the file CentOS-6.7-i386-minimal.iso.

For x86_64, download the file CentOS-6.7-x86_64-minimal.iso

Make sure file IS NOT LiveCD and extension is ISO, but not .torrent!
