   I got myself a cheap rip-off of the Saleae Logic 16 analyzer from e*ay. The   
   original costs way over a thousand bucks, and is capable of doing up to 100   
   MSPS on 16 channels , 16 MSPS when all 16 channels are used. Juuust enough.   
   The software is excellent    
   and extensible through their C++ SDK.   
      
   It's enough signal inputs to monitor the POS addressing:   
   CDSETUP#, CMD#, S0#, S1#, M/IO#, A[0-2], Data[0-7].    
      
   The original Snark Barker has debug pin headers to access all those signals,   
   plus I grabbed the card-exclusive CDSETUP# signal from the 9-K San Remo card   
   in question.   
   Stuffed this unusual setup in my RS/6000 -42T and took a 60 s long capture of   
   the whole AIX bootup process.   
      
   Then used the Saleae software to manually analyze all POS accesses to the 9-K   
   card from the BIOS, BOS and driver.   
   It's 36 accesses in total, and all very plausible.   
   The BIOS only reads out the Card ID in POS[0-1] and sometimes enables-disables   
   the adapter through bit 0 in POS[2].   
   The driver additionally sets the values to POS[2-5] for IRQ, DMA and IO window   
   as they could be read out later during AIX run time.   
      
   There's no access to POS[6-7], no signs of XPOS subaddressing at all. No   
   mysterious, unexpected reads or writes. All very simple and basic.   
      
   I'm afraid, we're on the wrong track here, and said patent does not have   
   anything to do with our 9-K adapter.   
   It must be using a completely different way of configuration, maybe through   
   the IO window.
