WinXp Pro 64 bits

[GakValadep]

Can I install / use WinXp Pro 64 bits Edition with a P4 2 ghz. and 512 mb. DDR with no problem?

your processor is 32-bit, not 64-bit. I'm not sure if it will even run, and if it will, you won't notice any difference from windows XP Pro 32-bit.

Windows XP 64-bit Edition is for Intel Itanium Processors only.

You cannot run this on a regular processor.

As soon as Intel releases a 64-bit P4 you can...

Assuming it's not a P4 with x86-64 rather than IA-64 that is

True, although I did hear MS has a x86-64 version of XP in the works along with thet IA-64 version.

Quite correct, it's supposed to come out shortly (who know how long that means) after the desktop version of AMD's Opteron. No one has confirmed whether it will work along with IA-64 or if they have to remain seperated. (Naughty Giant's in their playground that don't get along very well)

Well I'm sure the codebase is the same, but they probably won't be distributed on the same CD because Intel isn't aiming IA-64 at desktop consumers yet.

This is true, they are both coded with C++, but I was refering to the architectural differences in the hold registers between current and extended x86-32&-64bit and IA's proprietary 64bit register scheme of the processor itself, meaning that hardware logic is quite diffent, demanding different instruction sets entirely.

I'm pretty sure they use C instead of C++ for the core parts of the OS, and the compiler should handle most of it, I'm sure very little of the OS is coded in asm. For an example look at how Linux handles it, there's like 16 different architectures supported. All the architecture specific stuff is in arch/<architecture> and include/asm-<architecture> while the rest is all portable C.
