This setting only affects the panel power sequen- cer (i.e. which port needs special care because it hosts a panel whose power is controlled by us). It shouldn't affect the VBIOS. Again, the VBIOS has many options, set in the binary. I know free tools to dump them partially, but none to set them. The regular way is to ask Intel for their Binary Modification Program (BMP, may be compatible with Intel's Binary Configuration Tool [1]) *and* a description file for the Video BIOS Table format (.bsf IIRC). That .bsf file is specific to the chipset generation (I can't find one for Broadwell, sadly), though, one for another generation might work too. Sometimes these files can be found in graphics driver packages or FSP [2]. If you happen to get the Intel tool running, I advice to double check the result in a hex editor (e.g. there should be only the change you made, plus about two checksums). Nico [1] https://github.com/IntelFsp/BCT [2] Here is one for Kabylake (the closest I could find, might be incompatible though): https://github.com/IntelFsp/FSP/blob/Kabylake/KabylakeFspBinPkg/SampleCode/…

Making coreboot more accessible to end-users - ideas?
by Taiidan＠gmx.com 09 Aug '17

09 Aug '17

I am mainly looking for opinions from both average sysadmins and power-users Here are two sample questions and my replies. What stops you or has stopped you from using coreboot on your primary machines? (Gaming - It needs to play the latest games if I am to spend decent money on it as I don't have a good job right now - my D16 was my first purchase/flash once I found out I could do that and now I have a few other CB boards for other uses after I found out how really accessible coreboot is.) How can the end-user documentation be improved? What advantages are you looking for in a system that has open source (including init) firmware? (Me - freedom, repair-ability and semi-obscure features like IOMMU that actually work and can be easily fixed if they don't) Some things I have done so far: Recommended cpus list for several popular boards, as buying a low end CPU then having unsatisfactory performance turns people away. Board notes to provide warnings and advisories for coreboot/board "gotchas" that discourage people, such as not knowing they need to run fancontrol to have a quiet system Things I want to do: payload menuconfig for common payload configurations such as disabling option roms, loading grub.cfg's from disks, etc. List of boards with verified special functionality (iommu, egpu, etc)

Lenovo X1 carbon 3460 Screen stays black
by Jo 09 Aug '17

09 Aug '17

Hello Guys, I wanted to get coreboot on my Lenovo X1 Carbon 1gen (3460) , so i followed the tutorial, however after flashing it, the screen stayed black.So i flashed the Vendorbios back and im kinda stuck now, help would be really appreciated. This is my*config file* (if you care to have a look) https://pastebin.com/FYrsmXPb and the output of *inteltool -m* (spd data) https://pastebin.com/JZQYb3p3 also the output of *inteltool -g* https://pastebin.com/wDNRxM4U _and i*nteltool -G*_ https://pastebin.com/zJV3dE8A _cheers _

DIY Laptop with a desktop board
by Taiidan＠gmx.com 08 Aug '17

08 Aug '17

I am considering creating a DIY laptop that can fit an ATX board with a 35W CPU - such as KCMA-D8 with a EE series opteron. Has anyone here done this before? are there some potential gotchas I haven't thought of? making a custom "1U" case with a screen and keyboard doesn't seem that difficult in theory - I would use a minibox ATX plug PSU for power with the round laptop style ac adapter plug for it. Potential Issues: Battery (are there any off the shelf models? probably sold as an integrated ups or w/e) I suppose I can live without one as I am hardly ever away from an outlet. Graphics (riser + fan shroud to help remove hot air? the integrated graphics are terrible on these boards) Keyboard (for the "beta" I would machine a custom case for a usb laptop style keyboard) Lack of a dock connection (but this could be fixed via external PCI-e and an enclosure such as the ones from Cyclone Systems - or a PCI-e to expresscard card.) Am I nuts for wanting to do this? it seems like the only way to get mobile freedom/performance. If I do it would anyone be interested in buying one with a modest markup?

The payload is SeaBIOS. You have to set your VGA BIOS to a VESA mode AFAIK. In text mode, only one display can be enabled. Though, I don't know how to do that with SeaBIOS. There might be a compile time option? There are also many options inside Intel's VGA BIOS in a structure called Video BIOS Table (VBT). IIRC, you can set it to start in VESA mode with multiple displays there. There's also an open-source solution for Intel gfx bringup, libgfxinit. Alas, it's not ready to use on Broadwell (it works generally just some steps are missing to make it work with coreboot). Nico

Opteron 16 core Turbo 2 FYI
by Taiidan＠gmx.com 07 Aug '17

07 Aug '17

In case anyone is wondering I found out that to get Turbo 2 on a 16 core opteron CPU AMD means 4 threads per node (as an opteron 16 core is technically two 8 core cpus in a single socket) not 8 threads on one node with the other node idle, I couldn't find a mention of this on AMD's site unfortunately - at least now I know as to why my turbo 2 seemingly wasn't working with more than 4 cores. The linux scheduler isn't aware of this, or even aware of modules - it will place threads on different modules wasting power and making it so turbo 2 doesn't work. Threads must be assigned manually after using the isolcpus command :[ unless there is something I am not aware of.
