Boot Manager Function
Boot Manager Function
• Controls boot order and location of all operating systems and EFI applications in the system
• Configuration and maintenance of preboot firmware, that is:
–EFI applications and operating system installation and location
–EFI drivers’ location in the system
–Boot manager options (typically stored in NVRAM)
–NVRAM maintenance menus
–Hardware diagnostics and test
–Flash update
Boot Manager Policy
• It executes policy for ordering EFI boot devices; it is an EFI application that is packaged with the core
• It is the only interface the end user should see
• An example boot manager in the EFI core source is on the web site; boot policy is not specified! (OEM value add)
• It uses EFI NVRAM (flash) to store paths and boot order (specified requirement)
• OEM should customize the boot manager for the look and feel, as well as for security
• For production, boot straight to the operating system
–You do not need to use built-in shell or startup.nsh
• The shell is typically included in most EFI systems as a boot option (but not required); it might vary between different builds and system to system
