At the risk of sounding like a corporate shill: what's wrong with Google Hangouts? It's got a web interface and native clients for Android and iOS. (I'm not sure if you still need a binary plug-in for Firefox, but at least Chromium can run it natively via WebRTC.)

Everyone, Idwer, I have radare question : I played until this point : c:>radare2 -e asm.bits=16 -e io.va=true i946gz.bin -- radare2 is WYSIWYF - what you see is what you fix [f000:fff0]> S $s-0x10000 0xF000:0x0000 0x10000 0x10000 bootblk rwx [f000:fff0]> e asm.segoff=true [f000:fff0]> s 0xf000:0xffff0 [f000:ffff]> How can I see the assembler code from there ? It's started from FFFF0....I'm sure the last byte instruction is jump to 0x00000 Cheers

[RFC] Finding a conference call solution for the CCC
by Paul Menzel Nov. 4, 2016

Nov. 4, 2016

Dear coreboot folks, At the last coreboot community meeting (CCC) [1][2], some participants couldn’t here what other participants were saying with the current conference call solution Discord [3]. As this greatly reduces the productivity, the conclusion was to find a different solution, as this problem has been present since the beginning and Discord doesn’t seem to be able to fix this. So either somebody gets in contact with Discord, and they promise to work on a solution for the next meeting, or we need to find a different solution. The requirements are. 1. Working conference call (audio) functionality 2. No registration necessary 3. Clients for all operating systems (packages at best in distribution archive), or at least a Web client that runs with Mozilla Firefox (ESR and last version), and Google Chromium (last version). Chris(?) offered to set up a Mumble [4] server. Clients for all operating systems are supposed to be available. Also Tox was mentioned [5], which doesn’t feature a Web client, as far as I can see. So if you know of a solution, please tell us, so that technical problems won’t spoil the fun of the CCCs. Thanks, Paul [1] https://www.coreboot.org/Coreboot_community_meeting [2] https://coreboot-meeting.pads.ccc.de/CommunityMeetingTopics?

Fund a TALOS Secure Workstation as coreboot build system
by Paul Menzel Nov. 4, 2016

Nov. 4, 2016

Dear coreboot folks, At the last coreboot community meeting (CCC) [1][2] the TALOS Secure Workstation was brought up, and most people said, they won’t be able to afford the base system. Martin said it’d be great to have one system as a coreboot build system, and suggested that the coreboot community together funds a workstation. What do you think? Thanks, Paul PS: Please spread the word of the crowdfunding to your friends, and coworkers, and support it, so that it’ll be a success.

You need ME (Management Engine) and FSP (firmware support package) blobs. I am not sure if you can legally obtain the blobs from Intel, but you can extract them from Chrome images. Best, Andrey

Are there any updates according thinkpad-X201-support?
by Philipp Stanner Nov. 3, 2016

Nov. 3, 2016

The wiki-article lists several issues, primary: * Most times after suspend an EC IRQ hangs in the queue and all functions keys stopped working until cold boot. * *Commit 456f495d broke USB and PCI-E* (unable to boot from live ISO on USB), a hard reset to commit a3e41c08 fixed the boot issue Is this still up to date or has it been fixed? greetings

Yes, there are only Chromebooks. Only few people care about the lower performance (i.e. Atom processor based) Intel platforms. Nico

I'm still waiting for intel guys ,I think that they can say more about this.

(I do not believe it does, but wait for a more experienced person to reply.) Information for you as a new member of the community: The past 5 years intel (and AMD FM2/AM4) platforms are generally pretty locked down, it is very difficult to install blob free or even semi-open firmware replacement on them even if you could somehow get the documentation. (which they will never give a mere mortal like us) and the newer intel systems have something called "Boot Guard" which is a CPU enforced code signing mechanism to prohibit the installation of open source firmware entirely. You shouldn't buy intel if you want anything even somewhat libre friendly (at least AMD gives lip service to foss) https://www.coreboot.org/Binary_situation https://libreboot.org/ (more info on foss compat here, just ignore the politics) Anyone who says they have a post 775/771 system that is 100% blob free open source is lying, that includes the purism scammers. At this point for new systems you have select ARM and OpenPOWER systems (like the Raptor TALOS and the Tyan Palmetto, both HPC workstations/servers) I believe there are a few 100% FOSS laptops out there that aren't listed on the coreboot site but my age betrays me and I am forgetting what they are called. (I say again purism is a scam, do not buy from them.)

Re: [coreboot] EC problem in X200s?
by Merlin Büge Nov. 3, 2016

Hi Iru, > Recently, I flashed libreboot to my X200s (with L9300 CPU). But it seems > that there are some EC problems in X200s, which I haven't found in a X200. Be aware that there are different EC versions. One should therefore upgrade the BIOS/EC (one process) to the latest version before flashing core/libreboot. EC updates are known to fix bugs and also to improve battery handling. Can you please post the output of: cat /proc/asound/cards You can still upgrade the EC, but it's much work. You'd have to flash an older BIOS version with flashrom , then upgrade with the regular stock ISOs to latest BIOS/EC version [0], which will update also the EC firmware, and then reflash libreboot. > 3.

Some user on #libreboot reported that with an X200 Tablet (similar hardware) and EC v1.06 he had *not* this issue.
