    You can check Intel's website for your CPU model to see if yours is 64-bit capable. If you don't know the exact model, Intel has a CPU identification utility that you can use. If you don't have a copy of Windows on your box, you can probably find a CPU identification tool on one of the various utility liveCDs out there such as Parted Magic.

    Thanks

    I found the answer
    It seems that even though the cpu can handle 64 bit...My current system has installed 32 bit o/s

    the cpu flag lm = long mode which means that the cpu can handle 64 bit o/s

    This is present in the following line

    flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca cmov pat pse36 clflush dts acpi mmx fxsr sse sse2 ss ht tm pbe nx lm pni monitor ds_cpl tm2 est cid
