 Ondrej: Thanks a lot indeed!  These documents seem to have the essential 
interface details all covered, except for Fast-20 SCSI adapters, which I 
guess are a minor modification from the software's point of view.

 Khalid: I have skimmed over these documents and I infer 24-bit addressing 
can be verified with any MultiMaster adapter, including ones that do have 
32-bit addressing implemented, by using the legacy Initialize Mailbox HBA 
command.  That could be used to stop Christoph's recent changes for older 
adapter support removal and replace them with proper fixes for whatever 
has become broken.  Is that something you'd be willing as the driver's 
maintainer to look into, or shall I?
