Is there a way to tell if an Intel CPU can do 64-bit or not?

Hi.

I have a few years old Pentium 4 machine, but I don't know if it can do
64-bit. Is there a way to check without installing and running the
installed OS? Can I use a LiveCD (which one?), look in BIOS/CMOS
(didn't see anything to mention it), etc.?

Thank you in advance.

Go to www.cpuid.com and download CPU-Z, latest version 1.44.
When you run it check 'Instructions' on the CPU tab. If EM64T
is listed, it's a 64 bit CPU.

Um, I would have to install Windows to use it. I said "Is there a way to
check without installing and running the installed OS?"

You can start here if you know the exact model of your CPU:

I have no idea which model it is though.

You could try 'dmesg' or 'cat /proc/cpuinfo' in a terminal window
(aka command prompt, aka xterm).

Caveat: They rely your kernel recognising the CPU correctly - that
will depend on how up to date it is (considering that your OP
header listed FC3, 2.6.11 as your platform).

There is a five digit code on top of the chip that begins with SL. What is
the code on yours?

No, that was another computer I was using via SSH. This is for another
computer I need to analyze.

Oh, I forgot to say without opening up the case earlier. I guess that
would work. Do I just Google that serial number/code to get the answer?

Place your SL code in the sSpec search box. This should get you to what
you're looking for.
