Once again, use at your own risk. This is my old patch to change the refresh rate of VESA_800x600 mode. It works by setting 1024x768 vesa mode to get the higher dot clock and changes back the display size parameters to those of 800x600, so we end up with a 800x600 mode with higher refresh rate. This is more a hack than a real solution, and a proper splxxx() call is needed around crtc programming code to be safe. Also the vidcontrol part is now irrelevant, as the dimensions can be specified as arguments to vidcontrol. /Mike To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
