6474.0. "2100A/KZPSA config" by LOTIMA::P_MORRIS () Thu Mar 13 1997 08:57

    Can anyone tell me whether the following config is supported:-
    
    Alphaserver 2100A RM (Lynx) 5/250 with 3 CPUs
    1Gb Memory
    SRM Version 4.4
    
    PCI config:
    bus 2 slot 1 PKA0 NCR----on board SCSI
    bus 2 slot 6 EWA0 DECchip 21140 DE450
    bus 0 slot 6 VGA    S3Trio
    bus 0 slot 7 PKB0 KZPSA--to--HSZ40
    bus 0 slot 8 PKC0 KZPSA
    bus 0 slot 9 PKD0 KZPSA--DWZZA--TZ877
    
    Digital Unix V3.2D-2
    All KZPSAs are running Version A10 f/ware
    
    Also would it be supported to fit another KZPSA behind the PCI to PCI
    bridge ie:4th KZPSA ?
    
    If so ,am I right in thinking that the customer would have to add the
    following to his kernel config(bus_probe_algorithm set to new) file 
    for the 4th KZPSA:-
    
    pza3 at pci2000 slot 7 (assuming next slot down to DE450)
    scsi4 at pza3 slot 0
    
    bearing in mind that the "new" KZPSA would become PKB0 as the top slots
    are probed first.
    
    The reason for this question is that this customer has had a lot of
    problems recently when trying to add a 3rd KZPSA,basically because of 
    not having A10 firmware & not editing the kernel config file correctly.
    However with a KZPSA in the secondary pci & runing sizer after booting
    the genvmunix kernel on Unix V3.2D-2,sizer doesn't actually return the
    correct value for the pci bus ie: should be pci2000 ,it actually
    returns pci2 instead.If pci2 is used instead & the kernel is rebuilt
    the relevant KZPSA & devices aren't seen by Unix.
