Add eot fonts via @font-face (for IE)

I can't make FCKEditor see my eot fonts:

Descriptoin:

CSS (inline on page with Editor), I put some text with such font-family on page before editor, it's work right. It meens that path to eot file and its format are correct.
----------
<style>
@font-face {
font-family: Salernomi J;
font-style: normal;
font-weight: normal;
src: url(salerno.eot);
}
----------

FCKConfig, Salernomi J - it's my font, I see it in menu in dropdown menu, it means that I work with right config file.
----------
FCKConfig.FontNames = 'Salernomi J;Arial ;Comic Sans MS;Courier New;Tahoma;Times New Roman;Verdana' ;
----------

Problem:
----------
FCKEditor show my my font as Tahoma(my default font).
