275  * This routine looks for the VGA PCI header.  It checks to see that bit 1 
281  * command register and have the proper effect (enable trapping of VGA).  
282  * Otherwise, if we enable VGA via the PCI header, trapping really won't be 
283  * enabled and the VGA register writes will go out to the external card.
326  *    Bit 0: Enable VGA IO
327  *    Bit 1: Enable VGA memory
361  * This routine sets the standard VGA sequencer, graphics controller, and
365  * the "gfx_vga_restore" routine.   Most OSs that use VGA to set modes save
366  * and restore the standard VGA registers themselves, which is why these
