KERN: intel_extreme: getting EDID on port C failed : No Error (8) }}} It does set a resolution though of 1024x600, does this sound like the correct native resolution of your built-in lcd? Could you try powering on/booting Haiku with an external monitor attached to the system without any safe video modes? -- Ticket URL: <http://dev.haiku-os.org/ticket/7487#comment:2> Haiku <http://dev.haiku-os.org> Haiku - the operating system.
