Hi ,

but I could not get it.

How to modify the mof file and asl file.

Thanks a lot

[WmiMethodId(1),

// The output will show nothing.

[WmiMethodId(2),

read, write
] void NeilBIOS6([out] BBBuffer OutData);//GetCompalKeystone1
// The output will show"The objOutParams.OutData variable contains an object."

};
