853.0. "AS1000A 5/400 KZPSA behind bridge" by QBUS::E_BURKHALTER () Thu Mar 06 1997 17:13

    
    The information below maybe incorrect.
    The FE will try to clarify tomorrow.
    
    The customer has two brand new AS1000A 5/400 with a KZPSA in each.
    The systems run VMS 6.2xx.
    
    With the KZPSA on the primary PCI bus, system runs fine.
    
    If the customer installs the KZPSA on the secondary PCI bus,
    on POST the receive a messag about the IRQ not being correct.
    
    This happens on eith system and with multiple KZPSAs.
    
    Has anyone seen anything like this?

853.1NT does not support the KZPSA behind the PPB only KEIKI::WHITEMIN(2�,FWIW)Thu Mar 06 1997 21:1744
    
    
    
    
    Interesting that this is not noted in the ASRV1000 firmware release
        notes but is in the ASRV2100 firmware release notes.

         The console may issue a message with older KZPSA's installed on     
    |
         the PCI bus behind the PCI-to-PCI Bridge chip [PPB]. The message    
    |
         may occur on power-up or after an INIT command. The message can be  
    |
         ignored for OpenVMS and Digital UNIX systems.

         The message is informational for Windows NT systems because Window  
    |
         NT systems currently do not support the KZPSA behind the PPB. The   
    |
         KZPSA is supported when installed in front of the PPB.

853.2Thanks, reply #1 was correct.MSDOA::WILSONWed Mar 12 1997 14:156
    I went on-site and got the correct error message from the system and it
    is the same as listed in the first reply. (Unable to assign PCI base
    address).
    
    When we defined the boot device properly as dkb it booted into the
    cluster ok.                     f
