VBT is also documented by intel-gpu-tools: https://cgit.freedesktop.org/xorg/app/intel-gpu-tools/tree/tools/ There's intel_vbt_decode (former intel_bios_decode) available intel_vbt_decode.c that will print all tables in human readable form: https://cgit.freedesktop.org/xorg/app/intel-gpu-tools/tree/tools/intel_vbt_decode.c Here is the self-sufficient context in one single directory (done on Fedora 25 latest upgrades - author himself tested the tool in given context below), extracted from the following web site: [user@localhost intel-gpu-tools]$ gcc intel_vbt_decode.c intel_device_info.c -o vbt [user@localhost intel-gpu-tools]$ ls -al total 352 drwxrwxr-x. 2 user user 4096 Apr 8 07:33 . drwxrwxr-x. 4 user user 4096 Apr 8 07:32 .. -rw-rw-r--. 1 user user 4123 Apr 6 20:18 drmtest.h -rw-rw-r--. 1 user user 12889 Apr 6 21:07 i915_pciids.h -rw-rw-r--. 1 user user 27736 Apr 6 20:46 igt_core.h -rw-rw-r--. 1 user user 9816 Apr 6 20:44 intel_batchbuffer.h -rw-rw-r--. 1 user user 28814 Apr 6 20:03 intel_bios.h -rw-rw-r--. 1 user user 6236 Apr 6 20:15 intel_chipset.h -rw-rw-r--. 1 user user 6796 Apr 6 21:05 intel_device_info.c -rw-rw-r--. 1 user user 3310 Apr 6 20:14 intel_io.h -rw-rw-r--. 1 user user 116344 Apr 6 20:47 intel_reg.h -rw-rw-r--. 1 user user 54812 Apr 6 19:58 intel_vbt_decode.c -rwxrwxr-x. 1 user user 54928 Apr 8 07:33 vbt [user@localhost intel-gpu-tools]$ WARNING: Please, do note that additional packages might be requested due to missing DRM definition files?! For me to make this package work on the bare F25 notebook, I needed to do few package installations, and few /usr/include .h files copying, since these files were expected to be on other/adjacent directories. I needed to install the following packages on Fedora distro to make VBT parser to compile into human readable format:  libpciaccess-devel : PCI access library development package, Repo: fedora  libdrm-devel : Direct Rendering Manager development package, Repo: fedora Then, as already noted, I copied some files to adjacent directories, as shown below: [user@localhost include]$ su -m Password: [root@localhost include]# pwd /usr/include [root@localhost include]# cp drm/drm.h . [root@localhost include]# cp drm/drm_mode.h . With this Human Readable Interface dumper the following should be possible:  Make a "decompiler" that would convert VBT from the option ROM into a human/machine readable text format;  Make a "compiler" that would take that text format and create a binary VBT from it;  Put the binary VBT into the ACPI IGD OpRegion table (or wherever the graphics driver can find it).
