My driver (based on 1.4X) such as it is, can see the SII chip, can 
initialize it and give it some buffers to work from. Going with Isildur's 
assertion that the protocol is simply MSCP I've been trying to get some 
more information on that protocol from various sources (including ultrix 
drivers).  But it is tough sledding. The MSCP protocol is protected by a 
patent and DEC was none too keen on it being used without a license so 
documentation on it is skimpy at best.

I'm also trying to absorb the NetBSD 'bus*' concept to because there will 
be a new bus here to support this (and it should probably be CI bus but for 
now it's going to be a subset in my stuff). There are some functions that 
automatically move data from the bus into the kernel and I'm hoping to use 
those with this driver. My next milestone is to send an enquire transaction 
to the 8 DSSI targets and to get back information on each of the devices 
attached.
