Setting Lyx to use biblatex package

First, read this website: biblatex and Lyx

The steps that work for me are :

1) With LyX 1.6.0 and newer:

• Put the file biblatex.module in the layouts folder in your user directory. (Help→About LyX tells you where you can find this directory; in the latest versions of OSX the correct layouts folder is in the applications folder).
• Run Tools→Reconfigure, restart LyX and select the module “Biblatex-citation-styles” from Document→Settings→Modules.

2) In the document preamble (Document→Settings→Preamble), load biblatex manually. If you want to use an author-year style (and thus use the above module/layout addition), you have to use the package option “natbib=true”. So, for instance:

usepackage[style=authoryear,natbib=true,backend=bibtex]{biblatex}
For a numeric or alpha-numeric style, you just need something like:

usepackage[style=numeric,backend=bibtex]{biblatex}
NOTE: setting biber in tools DOES NOT WORK FOR ME…
4) In the document, insert the BibTeX inset (Insert→List/TOC→BibTeX Bibliography… ) in a LyX note or comment, such that LyX finds the citations, but no `bibliography`command is output to LaTeX. It does not matter which style you chose here, so you can stick with “plain”. However, in order to use the citation dialog, you’ll have to choose the correct databases (i.e. those you loaded above in item (3)).
