    I'm fairly sure that the One's hardware platform (Atom N270 paired with Intel 945GSE/ICH7-M) supports both the Execute Disable Bit and the SATA AHCI Protocol. As i know, at least until BIOS 3309, there is no way to enable them via the BIOS (the latter may be useful to improve performance and reduce power consumption, if used with a supported OS).

    Has anyone some kind of information about that ?

    Thanks for your attention.

    Interesting. I have no help but I would like to know what the ram support is. I have found other posts where the 954GME supports 4gb where as people have installed 2gbx2 (in other computers). But I have the datasheet which says it supports 4gb but only 1gb per slot.

    Life is so confusing.

    Atom probably doesn't support hardware Execute disable bit function. Acer didn't write the ahci function into the bios so you can't enable it.

    Jack, please check http://download.intel.com/design/proces ... 320032.pdf at page 6.

    I'm glad to know Acer didn't put them in the bios.... :lol: how about enabling those two writing CMOS registers directly ?

    Cheers

    No info here .




    I would like to know how to slow clock

    on N270 .

    Computers are slow NOT for slow clock , but

    for Bloat software .

    Linux is bloat ,slow .







    Is N270 software limited to
    special N270 , x86 assembled code ?
    Or exists there older x86 code that runs .

    I.E. old debuggers , disasembers , to view the O.S. .
    I cant do the steep learning curve of C nor C++ .
    I can learn code 100 times faster by simply executing the
    AAO O.S. in a disassembler ..

    I have a 751h and would like to enable the virtualization feature of the Z520 processor. Acer support was of no help. The BIOS doesn't have an option to enable it. Anyone have an idea where I might poke values to turn it on?

    I don't see this option in the chipset register list... it would be easy to figure out if it were in there.
