Re: [coreboot] No VGA output on e350m1 after flashing. what to do?

Hi! On 30.06.2013 19:28, Christian Weinz wrote: > Maybe I didn't include the VGA option in the make menuconfig process. > How can I solve this problem? You need to add the VGA Option ROM (VGA BIOS -> Add VGA BIOS image). I've extracted it from the UEFI, but you also could use these: http://www.coreboot.org/index.php?title=ASRock_E350M1&oldid=11114 at the end of the page or you also may be able to use the default AMD fam14 (Persimmon) vbios. You will need to agree to the click through: http://wwwd.amd.com/support/vbioslic.nsf/userverify?openform http://www.coreboot.org/AMD_DB-FT1_PERSIMMON It's a pity, that bios_extract didn't work for now. You could use the AMI Aptio EFI MMTool with wine: http://win-lite.de/benutzer/fernando/BIOS-Tools/AMI_Aptio_EFI_MMTool_v4.50.… You need to extract OntarioEFIVbios with PCI ID 1002,9802 as Option ROM.

ASUS KCMA-D8 workstation board port offer
by Timothy Pearson 20 Jan '17

20 Jan '17

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 All, After reviewing some of the comments on the ASUS KGPE-D16 being essentially too large of a system and too expensive for many people, and the fact that modern, blob-free systems are not really available in the mid-range arena, Raptor Engineering would like to offer to create a native initalization blob-free port for the ASUS KCMA-D8, which is essentially the KGPE-D16's ATX-compatible "little brother". We would be asking $15,000 for the port, including upstreaming to the master coreboot tree. We already have extensive experience with these Family 10h/15h boards, and would be able to create a port of similar quality to the existing KGPE-D16 source in terms of both code quality and overall functionality. If this is something you might be interested in please let me know. We are able to accept multiple payments from various sources for the same project (within limits), so if this is something your local Linux groups or similar might be interested in we should be able to keep the cost on any one individual or organization to a reasonable level.

Re: [coreboot] On Intel Boot Guard
by Alexander Couzens 15 Apr '16

15 Apr '16

Hi Iru, we aren't still sure which boards use Intel Boot Guard and which doesn't use it. But we expect most board use it, because it's "recommended" by intel - as we dont recommend it. Also there isn't yet a test script for Intel Boot Guard. Can you post a link to that forum post? I would like to look into a x240 flash image. If you have such board it would be nice if you can send me a copy of the flash image via private mail.

Target candidate: Dell Latitude E4300
by persmule 17 Mar '16

17 Mar '16

Hi, I have found a potential target Dell Latitude E4300 for libreboot (and coreboot), for its similarity with Thinkpad X200S and X200T. This one uses GS45, with (S)P9X00 family cpu (its sibling model e4200 uses SU family cpu), like the X200S and X200T which is supported in coreboot (and libreboot) with gerrit's patch. And not like Latitude E6400, this model uses DDR3 RAM (more like X200S/T). This model uses SMSC FDC37M602, which is already supported with coreboot. Because the succeed for GS45 in X200S/T, I think it's a good porting target for coreboot and libreboot. I managed to get the firmware layout with flashrom(1), which is attached with stdout of flashrom. May they be useful to you. What does the community think about this? Worth it? And, waiting for certain goods' arrival, I plan to disassemble my E4300 to cleanse its cooler and heatsink, and siphon out the whole BIOS image, which will be sent to you soon, too. Regards, Persmule.

On Memtest86+ change sets up for review
by Paul Menzel 29 Feb '16

29 Feb '16

Dear coreboot folks, There are patches up for review [1], creating a new memtest86plus project [2]. Martin, as you are the author, could you please give a little bit more information? The last Memtest86+ release seems to be from 2013, and looking at your change sets there are a lot of patches applied from the distributions. So there is not much maintenance going on upstream. I could not find a mailing list, but there is some activity in the forum [4]. I am interested in what the goal is? Do we want to be the new Memtest86+ upstream? Have you talked to the Memtest86+ folks, so that they are informed? Will they hand over the domain for example? Thanks, Paul [1] https://review.coreboot.org/#/q/project:memtest86plus [2] https://review.coreboot.org/#/c/13818/ [3] http://www.memtest.org/ [4] http://forum.canardpc.com/forums/73-Memtest86-Official-forum

Fwd: Aspirant for GSOC 2016 with coreboot for ARM64 qemu port
by Saket Sinha 29 Feb '16

29 Feb '16

Hi, Congratulations to the coreboot team for selection in GSOC 2016. I am looking forward to participate in GSOC 2016 with coreboot for ARM64 qemu port. I request you to guide me as where to start with to prepare for this project. Regards, Saket Sinha ---------- Forwarded message ---------- From: Saket Sinha <saket.sinha89(a)gmail.com> Date: Fri, Feb 12, 2016 at 10:24 AM Subject: Aspirant for GSOC 2016 with coreboot for ARM64 qemu port To: adurbin(a)chromium.org, coreboot(a)coreboot.org Cc: Patrick Georgi <pgeorgi(a)google.com> Hi, I think this is early for this but I am looking forward to participate in GSOC 2016 with coreboot for ARM64 qemu port. This is to discuss the idea further. I guess the project was a part of last year GSOC as well so we already have some base-work to start with. I request you to guide me as where to start with to prepare for this project. Regards, Saket Sinha

Hi, This is GS45, with (S)P9X00 family cpu (its sibling model e4200 uses SU family cpu), like the X200S and X200T which is supported in coreboot (and libreboot) with gerrit's patch. And not like Latitude E6400, this model uses DDR3 RAM (more like X200S/T). This model may be better than X200S/T, for it (at least mine) even lacks a ME. Because the succeed for GS45 in X200S/T, I think it's a good porting target for coreboot. It would also be an instant libreboot port, once in coreboot, being GS45. What does the community think about this? Worth it? Regards, Persmule.

Re: [coreboot] Building ChromeOS from source

Hello! As with everything else concerning a (presumably) open source project, I'm considering it. Still looking for a reasonably good reason.
