I sent Tyan a fairly comprehensive explanation of the problems with the Tomcat
boards, along with a request for support. However, I have yet to receive even
an acknowledgement of my mail.

This was, remember, the sixth time I'd contacted them on the subject. They
don't seem to be particularly worried about the fact that their boards are
broken.

These boards do not comply with the Intel MP spec. As far as I'm concerned,
they're not fit for the purpose for which they were sold, and as such, under
British Law at least, I'm entitled to a replacement or a refund. I suspect
that similar legislation is in force just about everywhere.
Penalties for false advertisement are also a possibility. Speak to your dealer
and/or local Small Claims Court or equivalent.

If I hear from them, I'll be sure to keep you posted.
