    I looked through this notesfile...can't find this one:
    
    customer has two identical machines - AS 4100's running 6.2-1h3.  One
    machine shows up:

    He is concerned about the 4100 VS the 4X00.  Any ideas why?
    
    Thanks,
    
    Karen

    
    This is controlled by console variable SYS_MODEL_NUM. Same deal for
    Turbolaser (8200/8400). Because the machines are basically the same (as
    far as parts are concerned) within a family it gets determined by
    console.
    
    Licensing and other software interested in the machine type use it, 
    otherwise it shouldn't matter.
    
    >>> set SYS_MODEL_NUM 4100 
    
    Regards,
    Dave.   

    The SRM console SYS_TYPE environment variable (EV) is also used -
    possible values are RACKMOUNT and PEDESTAL.
    
    SYS_MODEL_NUM=4X00 is the default. This can happen either because MFG
    does not set it properly (4100 versus 4000) or because someone clears
    the ESC NVRAM's SRM console EV storage region via the CLEAR_SRM_NVRAM
    console script or via manual deposits. I'm not sure how spare PCI
    motherboards (Saddles) are initialized re: SYS_MODEL_NUM and SYS_TYPE.
    However, I believe I saw somewhere in the upgrade/install instructions
    that the user is supposed to set these two variables after swapping or
    adding a Saddle.
