    1 Fail safe VESA driver is not the problem. That works fine when enabled.
     1Fail safe VESA driver is not the problem. That works fine when enabled. Haiku splash screen usually comes up properly.

    3 The VESA driver Works fine if I 'only' set the screen resolution from the Haiku boot loader and NOT enable the fail-safe driver option. Haiku splash screen always comes up properly. So, its the intel_extreme driver.
     3So, it is the intel_extreme driver.

    55If I don't touch anything and just let the computer reboot/boot up:

    7 I see the intel_extreme driver reads the monitor's EDID info (i.e. monitor screen resolutions and product info) then the screen goes black from that point. I never see the Haiku splash screen but it seems the system has finished loading. If I disable the monitor, reboot, wait till disk activity finishes, then reconnect - I have a display with the installer GUI options and I can either install or go to the desktop. Notice it looks like 'Screen' preflet shows the Intel driver info but not the correct monitor info since I disconnected the monitor.

    9 So, I'm asking can the intel_extreme driver force/provide a basic default VESA-compatible display of 800x600x32 @ 60Hz or 1024x768 @60Hz if the device is 8086:0042 or 8086:0046 (Ironlake Desktop/Laptop) - once it gets all the EDID info??? The resolution 1024x768 @60Hz is the default display used if I use the monitor trick so it seems to work for me. I can then test if it will use the higher resolutions if everything works as planned.

    11 Otherwise, my guess is just make the driver for IronLake (Gen5) work like SandyBridge (Gen6).
    12 I read they were basically the same for most things.
     11Just an idea...
