fncychap not applied to a chapter

Question

I'm using fncychap package with the option

\usepackage[Bjornstrup]{fncychap}

I wouldn't apply it to only the first chapter and instead apply to all the next chapter. How can I do? I mean I have the part of the acknowledgements created using

\chapter*{}

and after that I start the first chapter of my book

\chapter{first chapter}

I wouldn't have fancy in \chapter*{}

If you want different formatting for an "Acknowledgments" section, just define it as you like; for instance

\newcommand{\acknowledgments}{%
  \cleardoublepage
  \vspace*{0pt}% the margin from the top
  \phantomsection % if you use hyperref
  \addcontentsline{toc}{chapter}{\acknowledgmentsname} % if you want it in the TOC
  {\centering\bfseries\Large \acknowledgmentsname\par}
  \vspace*{\bigskipamount}% vertical space between title and text
  \noindent\ignorespaces % omit this line if you want to indent the first paragraph
}

\newcommand{\acknowledgmentsname}{Acknowledgments} % or whatever
% If babel is loaded, use also the following for the language
% in which the section is written; for instance
% \addto\captionsitalian{\renewcommand{\acknowledgmentsname}{Ringraziamenti}}

Then at the appropriate spot, issue

\acknowledgments

Change the formatting as you please. But, in my opinion, this should be a chapter like all the others (possibly not using fncychap, but this is personal opinion).
