Example #3

File: PciBus.c Project: mdaniel/virtualbox-org-svn-vbox-trunk

/**
  The Entry Point for PCI Bus module. The user code starts with this function.

  Installs driver module protocols and. Creates virtual device handles for ConIn,
  ConOut, and StdErr. Installs Simple Text In protocol, Simple Text In Ex protocol,
  Simple Pointer protocol, Absolute Pointer protocol on those virtual handlers.
  Installs Graphics Output protocol and/or UGA Draw protocol if needed.

  @param[in] ImageHandle    The firmware allocated handle for the EFI image.
  @param[in] SystemTable    A pointer to the EFI System Table.

  @retval EFI_SUCCESS       The entry point is executed successfully.
  @retval other             Some error occurred when executing this entry point.
