Hi Erik.<br><br>Still under NDA? Haven't it been lift last sunday?<br><br>Anyway: I don't know exactly the terms of the NDA, So if you can't answer me the following question, please say "no, I can't answer". I'm in touch with people having some compability issues with their Barcellonas and MBs, so could you tell us what are the configs you are dealing with?
<br><br>If that information is also under the NDA, really sorry for the question.<br><br>Sincerally yours,<br><br>Jones<br><br><div><span class="gmail_quote">On 9/17/07, <b class="gmail_sendername">Erik Lindahl</b> <<a href="mailto:lindahl@cbr.su.se">
