I am not sure if that is entirely correct. Having looked at the various mainboard revisions for Miata in the past along with the engineering errata I got the impression that at some point there has been a silicon fix (to the Pyxis itself I mean).

There are plenty of Miatas out in the FreeBSD committer community so... I no longer have any Miatas, I used to have both a MX5 and a GL model. -- Wilko Bulte wilko@FreeBSD.org
