Which is my architecture?

[pravlin]

I am using an Intel Pentium Dual-core E2160 CPU.
Which is the architecture of my system? i686 or x86_64?
Is there Fedora 10 DVD for i686?In the http://fedoraproject.org/en/get-fedora-all it is not listed.
Will there be any trouble if I install using i386 DVD?

[newiLuvatar]

seems like your cpu is a x86_64 architecture...
it shouldn't be a problem to install the i386 version, it is perhaps a little slower...

According to this page: http://www.intel.com/products/proces..._dual-core.htm you have a x86_64 CPU. And no, it wouldn't be a problem installing the 32 bit version. There is at least one thread about the differences between 32 and 64 bit architectures, but I can't find it atm, try the forum search.

But......
praveen@praveen-desktop:~$ uname --m
i686
Thats why I asked here.

Can I start downloading x86_64 DVD?

And

That "i686" from the uname -m is just the kernel saying what its bitness is and
not what the cpu bitness is.

Pravlin,

uname --m

is only showing you the architecture of the OS you have installed. According to the manufacturer of your CPU (intel) you have a 64 bit CPU. If you want to double check, I believe running

sudo lshw | grep width

should return your CPU architecture. I would install the 64 bit version, but that is just my opinion.

Pravlin,
Sorry about that, I'm in Windows right now (gaming) and can't check the commands. just run the command without piping through grep

sudo lshw

and find the section regarding your CPU.
