I'd like to know how can we find out if we've got the right Intel, or AMD
processor for this what was it now? Buffer overflow thing.
I'm sort of thinking, how recent would these processors need to be to take
advantage of this buffer overflow thing. I'm thinking I've missed the boat
there as, my motherboard was bought in spring 2003. that was the updated
version to the one I got very early on in 2003.

Subject: [access-uk] SP2 some changes geared at future hardware
> Microsoft have also released SP2 to harden its operating system; in other
words, Microsoft recompiled all its Windows system binaries to include a new
flag, GS, which will mitigate buffer overflows, a common method used by
criminal hackers (crackers) to overwrite legitimate code with malicious code
on your PC. A buffer overflow is the method the Sasser worm used to infect
PCs. Windows XP SP2 also makes important changes to core Windows components,
such as DCOM and RPC. (Flaws within the DCOM RPC led to the damaging MSBlast
attack last year.) And SP2 will also bring every Windows XP system
up-to-date, whether or not you've ever performed a Windows update
postinstall. Once you've installed SP2, you'll have SP1's updates plus all
the security patches released up through MS04-025.
> To fully block the aforementioned buffer overflow and the Internet worms
that feed on them you'll need to have the latest hardware. The No Execute
setting isn't present in the current hardware architecture of most 64-bit
and 32-bit processors on the market today. This data execution protection,
or DEP, is currently available only on newer AMD and a handful of Intel's
Itanium server chips. In other words, the new Windows DEP changes won't help
you unless you're running XP SP2 on a machine with AMD or Intel Itanium
processors.
