IIRC, there were some bug reports on non-Acer hardware (I don't think this involved Acer hardware, but this was some time ago...) where the wireless detection wasn't working with this, but if we forced it on, it worked fine. > + I saw there have some magic number when you access AMW0_GUID1 (e.g. > 0x9610, eax, ebx, ecx) Could you please kindly teach me how can grab those > value for AMW0_GUID2?

For AMW0_GUID1, I got the stuff by using the Windows Kernel Debugger remotely to see what my laptop was doing when changing things in Windows - unfortunately that relied on a firewire port on the laptop, which I suspect most people don't have. The real problem is that I know almost nothing about AMW0_GUID2 - either what it's used for or what it actually does, nor how hardware detection works with it present (if at all). -Carlos
