This option actually disables VGA probing kernel wide - it essentially skips all of video.S during boot, and then disallows any drivers that may depend on that data (VGA console being the prime example). While I am about 85% sure that probing the missing VGA/VESA registers will not cause any problems, the values read will be nonsense, and I wanted to avoid the possibility that any part of the code will blindly use the returned data without checking it. The option is triggered off of EMBEDDED, and I felt it would be buried deep enough to not cause heartburn to the casual user. Jordan -- Jordan Crouse Senior Linux Engineer Advanced Micro Devices, Inc.
