Specifying model in log-linear form


Sorry I am a bit of a novice with Dynare. I am interested in estimated
a model which already has its equations specified in log-linear form (not as deviations from the steady state). I also have other equations specifying the steady state and variables from these equations appear in the log-linear equations. So there is some inter-dependency between the two sets of equations. Is it possible to use dynare to estimate the parameters from this model with data? And how can I turn the log-linearsation of my equations off?

Any prompt responses would be greatly appreciated as I am working to a deadline.
