My test showed that MP i386 works as well. Amd64 is broken. --- Sent using a tiny phone keyboard. Apologies for any typos and autocorrect. This old phone only supports top post. Apologies.

In practice, as bde@ suggested, you may need to use UP i386 kernel and perhaps downgrade to earlier version of FreeBSD. Also you need to somehow acquire 34-to-50 cable or adaptor*. I made mine, so perhaps that why I failed :) You don't need to worry about tg43 signal if you don't plan to write on the= se floppies. In the end, after burning weekend on this little project, I realized that I risk to burn much more time, so I just ordered kryoflux. *) something like this http://www.classiccmp.org/dunfield/img54306/h/c8ssc.= jpg --=20 Alex _______________________________________________ freebsd-arch@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-arch To unsubscribe, send any mail to "freebsd-arch-unsubscribe@freebsd.org"
