Hmm, that's definitely not what I expected. For reference, my test ZT5550
here yields HCF_HCS = 0x31a in a standard (non-RSS) cPCI chassis, which
means both buses are active in my setup, and I'd expected the same from an
Active-Active or Locked Active-Active setup in a ZT5084 chassis. I'll dig
deeper in the host controller docs tomorrow as well as try and glean
something from the rough 2.2 RSS code Intel/Ziatech released in late 2001.
In the meantime, could you describe for me what you've got the "High
Availability" options in your ZT5550's BIOS set to? Also, just so I'm
clear on what your setup consists of, am I correct in my assumption that
you only have a single ZT5550 in your ZT5084 chassis?
