Screen Resolution during boot... |

Anyone know how to get the screen resolution at boot time into anything but 680x480 (ie when the apple and spinning cursor are up)? My 8600 w/G3/500 and ATI Rage Orion card switch from my normal mode (1024x786) to what looks like 640x480. Other machines I have seen stay at the higher resolution (these were not Old World machines). I tried setting the "output" menu selection to the Rage Pro selection in XpostFacto (normally it is set to none), but it does not seem to make any difference... Any suggestions? |

I'm not sure what controls the screen resolution in the boot process. I have an Apple 15" monitor that comes up in 640 x 480, and a KDS 17" monitor that comes up at 1152 x 870. (I prefer to debug startup problems on the KDS :-) |

I believe that the resolution defaults to VGA if the video card is not driving an Apple-branded monitor. There's a digital communications channel present on the Apple monitors that allows the resolution to default to the user's setting. When a video card that supports this digital channel is not hooked up to a monitor that also supports it, the video resolution defaults to VGA until the card's driver loads during boot up. The ATI 8500 in my G4 always comes up at the preselected 1024x768 resolution since I have an Apple 17" monitor hooked up. I have a Viewsonic monitor on the 9500 and the ATI 7000 always boots up at VGA and then switches to 1024x768 after the ATI driver loads. |

The same results have been reported with most ATI video cards (including my Radeon). This is very irritating because verbose mode is almost unreadable because of the text wrapping down to the next line. I asked Ryan about this about a month ago but he did not know how to fix it. -Ben |
