    Luckily, Windows's bootloader has supported the automatic choice of PAE vs non-PAE kernels since Windows 2000. And Windows XP SP2 and later tries to help by restricting the physical address space to 4GB by default. Linux's bootloaders do not have that support however and thus even today most Linux distros are installed by default with a non-PAE kernel that lacks NX/XD support. Only recently has Fedora 11 began to install a PAE kernel by default. What makes matters worse however is that even Intel's own Pentium M did not have PAE support until they were forced to add it because it is needed for XD support, and the same was true of VIA and Transmeta.

    #3: the thing is, its not really an inferior version - its actually exactly the same. I probably would not be surprised if there are some cross license things going on.

    #4: DDR2 speeds werent talked about in the roadmap, but i would think DDR667 at the very least would show up.

    Ok, a 1066 bus to support the 533 ddr-2. What about the 667 and 800 DDR-2?

    "Thus Windows XP SP2, Windows Server 2003 SP1 and dozens of Linux/BSD operating systems are all adopting (or have already adopted) the NX methodology of stack protection. Considering all hype around AMD's Sempron processor, the XD protection may force AMD to adopt their NX technology across all processors. Remember, only the high end, upcoming Sempron processors are NX enabled."

    HUH?

    So in a nutshell AMD system is implemented, and working, but Intel is coming up with there own inferior version, and everyone is jumping off the AMD bandwagon? Is this corect?

    Yes, they ought to implement all those functions on the Skt478 cpus as well. Pity AMD no longer fills the void left by Intel when they change (for no good reason) socket formats like the sckt7 days.

    Would it kill Intel to just follow AMD's lead for once? We need a NX function, and it needs to be universal - a format war like this helps no one.
