                WHY DOES HEWLETT-PACKARD ROLL THE BIOS ?
                 ======================================
  Minimizing  the number of the revisions of the BIOS is an  objective
  of  Hewlett-Packard. However Hewlett-Packard may have to release new
  revisions for any one of the following reasons :
  
  ENHANCEMENTS
  ------------
  This  is  the  case  when a major new feature is  available  on  the
  market. Good examples are Microsoft Windows 95, a new level  of  the
  Plug and Play standard, a new level of the PCI standard.
  
  PROCUREMENT ASSURANCE
  ---------------------
  Hewlett-Packard qualifies an additional supplier for a component  in
  order to secure the procurement.
  
  COMPONENT ROLL
  --------------
  A  semiconductor supplier introduces a new version of  a  component,
  and  stops  the production of the previous version for technological
  improvement reasons.
  
  QUALITY
  -------
  To  improve the quality, Hewlett-Packard has to make use of  a  more
  reliable component, or to implement a design change.
  
  COST
  ----
  Hewlett-Packard  uses  a different supplier  which  can  supply  the
  equivalent component at a much lower price.
  
  BUG FIX
  -------
  Bugs discovered in the previous version are fixed.
                                    
                                    
                               DISCLAIMER
