I read that Mandriva One cds are dual architecture and so I understood that to mean it had both x86 and x86-64 on the same disc.
I booted into live mode and didn't see any options to choose so I assumed it did it automatically.
I have now installed to disk and again there were no options so I still assumed it was automatically choosing the arch based on my comp.
After booting up the installed Mandriva I played around with various options and then checked for any updates. It asked me to select a mirror and every single one ended with i586 so it seems I am running 32-bit after all.
How do I get it to install in 64-bit?

<EDIT>
I just discovered uname -m. Output is i686

Well it's getting ridiculous. The only info I could find on the madriva website says that the x86-64 images were delyed 2 to 3 days because of some problem, but it still suggests the discs are dual arch.
I tried browsing through some of the mirrors and downloaded mandriva one from an x86-64 directory but after burning and booting the cd it is still saying i686.
