    Hi,
    I like to request a feature in the AMITool to allow free editing of the DSDT because of the OSI Method in many BIOS.
    In many BIOS AML code like this exist:
    If you notice the problem is there is no entry for Windows 2009 (aka Windows 7)
    This issue is present in many board released before Windows 7.
    Also the AML Code differ some OEM implement it this way:

    So there is no standard AML Parsing.
    For AML BIOS the MMTool doesn't allow easy parsing and editing so I hope AMITool will be able to do that in the future.

    Thanks

    Hi
    Sorry to bother you again but I noticed the new feature is implemented using iasl, a quirk of iasl is it tends to try and optimize DSDT by default problem is older OS do not like that and can cause boot failure.
    To solve that issue iasl has to compile using "iasl -oa DSDT.dsl".
    -oa has to be added to disable optimization to be backward compatible.
    The tool has become something to solve BIOS, OEM shipped with broken DSDT!
    Thank You once again.
