source: vbox/trunk/src/VBox/Main/include/DisplayImpl.h@ 17688

Last change on this file since 17688 was 17669, checked in by vboxsync, 15 years ago

Main: Rework storage controller handling to allow an arbitrary number of different storage controllers and remove code duplication:

  • XML format changed
  • New StorageController class
  • Removed SATAController (obsolete)
  • Removed the IDE controller code from BIOSSettings, handled in StorageController now
  • Property svn:eol-style set to native
  • Property svn:keywords set to Author Date Id Revision
