I previously inquired about supporting my LCD display's 1400 by 900 resolution, and it was suggested that I add the PCI Device ID for my graphics controller to the intel_extreme driver. The Detailed tab in the Devices app says that the Device ID 0x2e22 is a VGA compatible controller, but my motherboard doesn't have a VGA socket on it. The 0x2e23 is just listed as "Display controller", without any mention of VGA. Would that be the controller for my DVI port? I think the 0x2e23 is an Intel Graphics Media Accellerator X4500 or maybe X4500HD. I'm having some trouble finding the Intel datasheet that lists the 0x2e23 Device ID. I tried just adding 0x2e23 as INTEL_TYPE_GMAX4500 to: haiku/headers/private/graphics/intel_extreme and then added INTEL_TYPE_GMAX4500 to the supported_devices table in: haiku/src/add-ons/kernel/drivers/graphics/intel_extreme/driver.cpp I did a rebuild from the top-level, then verified with ls -l that the intel_extreme driver had been rebuilt. I installed it on my target box, rebooted and... ... still got VGA video - my video controller is still not recognized. ;-( Still I've made some progress in being able to figure out where all the sources are, and to do builds and stuff. Can anyone make any suggestions as to how I can figure out why my controller is still not recognized? I'm about to hook up the serial port to my Linux box so I can look at debug output. However my test box' serial port is on a PCI card - will that work as-is, or will I need to patch the sources somehow to be able to use a PCI serial port? There is an integrated serial port on the motherboard, but I don't have the necessary cable. This is all very exciting, to finally be hacking Haiku drivers. Thanks!
