Hi,
I commited some changes which adds full disconnect/reselect support
for the siop driver (and a fix so that it now works on my alpha).
If you're playing with this make sure you have:
/*      $NetBSD: siop.c,v 1.3 2000/04/25 20:02:33 bouyer Exp $  */

version 1.2 is definitively broken (I don't think this can lead to serious
disk corruption, but a lot of xfers may fail).

sync/wide negotiation is planned for the end of the week; tagged queuing 
should follow a few days later.
