   6           Some "legacy" VGA devices implemented on PCI typically have the same
   7           hard-decoded addresses as they did on ISA. When multiple PCI devices
   8           are accessed at same time they need some kind of coordination. Please
   9           see Documentation/vgaarbiter.txt for more details. Select this to
  10           enable VGA arbiter.
