In my Dell Laptop 1645 (Feb 2010 version), I have Windows 7, 64 bit. I installed OpenSUSE 13.1 64 bit. The BIOS is non-UEFI (atleast bios does not show any option for UEFI or secure boot – pretty old one 2010). I could boot GRUB2 as GRUB UEFI indicated incompatibility and error in installation. After Grubs based installation from OpenSUSE-13.1_64 bit DVD, I find installation has been done as i686 and not as x86_64. However, while I earlier installed old versions like 11, 12.2 etc. I could install in x86_64 mode.
I like to use softwares like netgen, OCC, Salome, OpenFOAM etc. Now If I install FOAM in x86_64 version it shows incompatibility. If I install i585 version it shows architecture should be transferred to i586 from i686. It becomes an World War for me to redo everything.
Since the bios is an old one upgraded from Dell till 2011 I hope it may not work in UEFI even if I try to install UEFI firmware. Rather, it will make the Windows non-bootable and I need to roll back.
If you used the 64-bit DVD image or the 64-bit live image, you should have a 64 bit install. If, instead, you used a 32bit install image, then you will have a 32bit install.
You can use the command:
That will tell you the installed architecture. On my system, it gives:
Linux nwr2 3.11.6-4-desktop #1 SMP PREEMPT Wed Oct 30 18:04:56 UTC 2013 (e6d4a27) x86_64 x86_64 x86_64 GNU/Linux
and you can see the “x86_64” there.
No, maybe you are saying that grub2 is 32bit. If so, then yes, that is normal. A 64bit install using MBR booting, uses 32bit grub2. The whole idea of MBR booting is based on the use of a 16bit system loader. So, during MBR booting, grub2 must initially run as 16bit. It then may switch to 32bit, to access higher memory addresses. As far as I know, only grub2-efi is built as 64bit, because the UEFI specification requires that the boot loader use the native machine architecture.
I tried to install OpenSUSE 13.1 using x86_64 DVD. I find that most of the installed files have architecture x86_64. However, while I wanted to see o/p of
in my system gives
Linux Aditya.home 3.11.6-4-desktop #1 SMP PREEMPT Wed Oct 30 18:04:56 UTC 2013 (e6d4a27) i686 i686 i386 GNU/Linux
The Hardware is Dell 1645 XPS studio 16 with i7 processor and 4 GB RAM. Earlier while I used older versions of SUSE 64 bit DVD, the installed OS became 64 bit.
This time I am surprised to see that 64 bit SUSE 13.1 DVD inatalls i686 version.

No, impossible. You downloaded the wrong DVD.
Open that dvd, and look at the header of the file “content”, or at the
structure of the “suse” directory. The 64 bit DVD does not have an i686
directory. Thee is an i586 directory with only one package,
As the 64 bit DVD does not contain an i686 kernel, it is impossible it
can install what it does not have.

I also believe that if the DVD contains x86_64 data, how can i686 comes in the picture. .
The first few lines of the header of the file “content” shows :

That is the reason why I have become mad!! I do not understand. Another point is that all the file installed were x86_64 version.

Well, it can only come then from online repos.

You are right, after installation, I installed several softwares using yast from internet like gnuplot, gfortran, lam, lapack etc.
However, if installation using YAST changes arch then there is problem, I think.
If I look for “kernel-desktop” in Yast software management, and I click the “version” tab, it shows me both the 64bit and the 32bit version. If careless, I could accidentally install the 32bit kernel. I’m not sure whether there would be any warnings if I tried.
