What do you mean exactly? Both VGA Option ROMs are from the vendor BIOS. From our conversation in #coreboot [1], is the following correct? 1. It did *not* work with the VGA Option ROM extracted from the firmware image file downloaded from the Lenovo Web site [2][3]. 2. It did work with the VGA Option ROM extracted from the system running the vendor BIOS [4]. Kyösti and Patrick suggested that the VGA Option ROM in the firmware image does not contain the necessary IDs for the used graphics card and the vendor BIOS adds these/patches at every boot.
I am now having trouble getting thinkpad_acpi working correctly.
Please start a separate thread for that. Thanks, Paul [1] http://www.coreboot.org/IRC [2] http://www.coreboot.org/VGA_support#RECOMMENDED:_Extracting_from_your_vendor...

Hi, You're most welcome to work on fixing the issues that you identify. Please push commits to gerrit for review once you believe that they are reasonably finished. uberushaximus@gmail.com wrote:

You'll have to look into why. Nobody will do it for you just because you send an email to a list. //Peter
