How can I say whether my 64-bit OS is IA-64 or x86 instruction set?

Hi All,

I have a computer which has 64 bit processor. How can I know whether it's x86-64 OR IA-64?

If you have a Windows OS on it, try running:
"wmic cpu list full" in the command prompt, otherwise I think your BIOS messages in POST will show...

Intel XEON(R). And if I google it, it would tell me, but I want to know a way where IF I do not ahave internet connection then system can tell me the kind of instruction set it is using.

IA-64 is reserved for the Itanium-based processors.  64-bit Xeon processors would fall under the x86-64

Oh yes, exactly. You are right but my question is is there any place in BIOS or control panel where my system tells me explicitly that this is x86-64 bit system?

No, unfortunately they don't store that data on the chipset.  You can only tell by the model.
