    [color=Blue]The CPU manual simply states that you can move any 32bit register into DR0-DR7:
    [code]
    mov eax, ... whatever ...
    mov dr0, eax
    [/code]
    Did you try the inline assembler for this? Also, if inline assembler does not serve these instructions - you can use __emit() statement to generate the byte codes.[/color]
