# fncychap not applied to a chapter

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*{}

Why should a chapter be different from the others? –  egreg Dec 22 '12 at 21:42
Because it is not a really chapter...it is the part of the acknoledgements –  Mazzy Dec 22 '12 at 21:43
So what? If it's a chapter treat it like a chapter. –  egreg Dec 22 '12 at 21:46

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

\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).
