   2 // BDSDxe module is core driver for BDS phase.
   3 //
   4 // When DxeCore dispatching all DXE driver, this module will produce architecture protocol
   5 // gEfiBdsArchProtocolGuid. After DxeCore finish dispatching, DxeCore will invoke Entry
   6 // interface of protocol gEfiBdsArchProtocolGuid, then BDS phase is entered.
   7 //
   8 // Generally, this module take reposiblity to connect all necessary devices for platform boot,
   9 // these boot device path are hold in PlatformBdsLib library instance produced by platform.
  10 // For legacy boot, BDS will transfer control to legacy BIOS after legacy boot device is select.
  11 // For EFI boot, BDS will load boot loader file EFI\BOOT\BOOTIA32.EFI, EFI\BOOT\BOOTX64.EFI,
  12 // EFI\BOOT\BOOTIA64.EFI file from selected boot device and transfer control to boot loader.
  13 //
  14 // BDSDxe also maintain the UI for "Boot Manager, Boot Maintaince Manager, Device Manager" which
  15 // is used for user to configure boot option or maintain hardware device.
