Can the 3gb be set on Win7 32bit? If so is the command setting it the
same as XP? I suspect that its not.

Thanks,

    I once read that this setting is no longer required in Windows 7, as it is already the default.
    However, I have not confirmed this.

    Thanks so far, have another tiny question:
    in xp we would set /3gb, then we had to add userva=2800 for the video
    card, or else the machine would not reboot.
    Would the equivalent be "bcdedit /set IncreaseUserVa 2800" ??

    bcdedit /set IncreaseUserVa 2800"

    This seems to have worked. Thanks all.
