    We had to run the ECU in order to get a new installation (tailoring
    the Factory Installed Software- in this case, DUNIX 4.0B-) to work.
    
    Fortunately, RDG knew about this. It was hard for us to understand at
    first, since there were no EISA options...
    
    Also some confusion arose from the fact that the distribution CD was
    labeled v4.0C, which doesn't exist yet. System banner says 4.0B as it
    should.

212.9When to run ECUHARMNY::CUMMINSTue Jun 03 1997 10:5228
    Have seen some questions from Field recently re: ECU and when it should
    be run. Here's a summary.. Once ECU has been run, it need not be run
    again unless:
    
      1. Your EISA/ISA config changes.
      2. You swap/upgrade the board which has the embedded NVRAM part used
         to store the config data. On 4000/4100, this is the PCI motherboard
         (aka the Saddle, which has the 8KB ESC NVRAM part on it).
      3. You clear the NVRAM part via deposit commands or SRM console-based
         script (e.g. CLEAR_ARC_NVRAM).
      4. You switch between booting NT and one of UNIX/VMS (or vice versa).
         E.g. UNIX will appear to hang during boot-up if NT ECU data is in
         NVRAM rather than UNIX/VMS ECU data. And it won't necessarily be
         obvious why it is hung (serial port, which typically hangs off
         Xbus, not configured properly).
         
    Note that even if no EISA options are installed, ECU must be run at
    some point (typically, in Manufacturing).
    
    There are some twists, however. For instance, AlphaBIOS, upon seeing a
    blank ECU data region in the ESC NVRAM part, will initialize said
    region with NT-specific ECU data (assuming an empty EISA bus). Another
    example is that the AlphaServer 4000/4100 SRM console will hard-code
    UNIX/VMS ECU data in the HWRPB data structure passed to UNIX/VMS during
    booting if it finds an empty ECU data region. [Note that SRM will not
    auto-update the data region, however, and it will warn the user during
    power-up that ECU should be run when it finds a lack of valid ECU data
    in the NVRAM part.]
212.104.0c is for PWSauBBPBV1::WALLACEPC: mega$ fashion accessoriesWed Jun 04 1997 07:002
    I think 4.0c does exist, but it's solely for PWSau support. Or so I was
    told.

Right.  And if you install using the V4.0C media on anything else, it
installs V4.0B instead.

Part of the confusion is that the release code named "PTmin", which is about
to enter field test, was once expected to be called V4.0C.
