Do I have XP 32bit, AI64 or x86-64?

I have the latest version (bought a last week) win. xp home. I am going to download a new drive and it ask if I have:

Windows XP (32 bit)
Windows XP (IA64)
...or
Windows XP (x86-64/EM64 T)

how can I find out mine?

What kind of processor do you have?

Ex. AMD Athlon 64 / Intel Pentium 4 / Intel Celeron / Intel Core2Duo

You get the point.

Then it would be XP 32 bit.
