Celeron CPU: 32 or 64 bit?

I currently have Fedora 17 32bit installed on an
old Dell with a Celeron processor. I would like to
know if this machine could run a 64bit version
of Linux. Appended is the current contents of
/proc/cpuinfo

Is this a 32 bit or 64 bit processor?

Thanks

I think I am able to answer my own question with
the command lscpu:

Code:

Architecture:          i686

CPU op-mode(s):        32-bit

Byte Order:            Little Endian

CPU(s):                1

On-line CPU(s) list:  0

Thread(s) per core:    1

Core(s) per socket:    1

Socket(s):            1

Vendor ID:            GenuineIntel

CPU family:            15

Model:                4

Stepping:              9

CPU MHz:              2533.270

BogoMIPS:              5054.06

L1d cache:            16K

L2 cache:              256K

Looks like a 32bit processor.

Indeed - it needs "long mode" (lm) flag for 64-bit.

Isn't there also usually a flag for EM64T or AMD64 on 64-bit too?

At least not on any of my 64 bit systems.

@chicagocoyote: According to the specs of your CPU you have the Celeron D 325, which was one of the last 32 bit only Celerons, its successor, the Celeron D 326 was already based on the 64 bit Pentium 4 CPUs.
Please keep in mind that Fedora 17 already reached its end of life, you should upgrade to a supported version.
