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

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?

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?

You can always download one of the 32-bit Linux live-cd's, such as
Ubuntu. Once you boot up into the cd, then all you would have to do is
run the command "more /proc/cpuinfo" at a command prompt. It should show
as one of its flags that either EM64T or AMD64 or x86-64 or x64 or
something like that is supported. I would assume it's most likely going
to be called x86-64 under Linux.

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

Thanks, that will work for my scenario. I just didn't want to tamper
with installation and the HDD. :)

Boot up your favorite Linux live CD, log in, and type this:

cat /proc/cpuinfo

The "flags" line will list everything that your processor supports.

A simpler go/no-go test would be to make sure it's an AMD64 live CD instead
of an x86 live CD...either it'll boot or it won't.

Tell us specifically which version/model of P4 CPU you have and we'll tell
you if it is 64 bit.

I forgot to mention that I do not want to open the computer case. So I
don't know which P4 it is.

Well, short of extreme measures such as X-raying the computer, you'll have
to find out by running some sort of program. To do that, you should either
say what operating system is currently running on the computer, or run
some sort of live CD. The latter has already been mentioned as a possibility.

So, at this point, why are you still asking questions?
