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

by Reiner Luett

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.

Re: [coreboot] How to improve the boot time of the Asus KGPE-D16?

by Daniel Kulesz

Hi, I wanted to try caching of the MRC training data. As described in Timothy's post, I commented the following line: > allow_config_restore = 0; However, I was not able to measure any effects regarding boot time. Does this setting only work with cbfs enabled? And if so, is it necessary to set additionally any cbfs variables? Cheers, Daniel P.S. Hope this time I've set the Reply-To header correctly. > On 03/02/2017 02:17 PM, Paul Menzel wrote: > > Dear Arthur, dear Timothy, > > > > > > Am Donnerstag, den 02.03.2017, 13:38 -0600 schrieb Timothy Pearson: > >> On 03/02/2017 01:30 PM, Arthur Heymans wrote: > >>> Paul Menzel writes: > >>> > >>>> I think most of the time is spent in RAM initialization. > >>>> > >>>> 1.

Where to buy the KCMA-D8? *brand new*

by Taiidan＠gmx.com

Does anyone know? I have checked everywhere I can't find the accessories for the board family either (TPM etc) I would just get another KGPE-D16 but I want to make a router with one of the 35W C32 "EE" opterons and the retail price is a little cheaper. And does anyone know how much longer they are making the KGPE-D16? I wanna buy more before they stop (I could get arm or power, but I still need x86 to play video games) I suppose it is possible to port to another better available similar board like something from supermicro (H8DGI-way, way better specs, first released 2014) but I have no idea how complex that is.

Current, BLOB free laptop available Europe?

by Paul Menzel

Dear coreboot folks, I am looking for a new portable device available in Europe. Is it true, that the Acer Chromebook R 13 [1], is the only current BLOB free device? The device currently costs 400 €. Is MediaTek “a good citizen”, that means, do they provide datasheets and work on drivers? The Samsung Chromebook Plus/Pro with RK3399 [2] are only available in the USA, right? Thanks, Paul [1] https://www.acer.com/ac/en/US/content/series/acerchromebookr13 [2] https://chromeunboxed.com/samsung-chromebook-pros-processor-rk3399-gets-ben…

Seeking developer interviews for the Denver conference presentation

by Marc Jones

Hi coreboot devs, I'm seeking several people that wouldn't mind sharing a little about themselves to interviewed for a fun and informative presentation at the Denver conference. The ideal candidate is someone that has contributed to coreboot and maybe isn't able to attend the conference. Please contact me if you wouldn't mind answering a few questions, sending a selfie, and photo of your development setup. Regards, Marc -- http://marcjonesconsulting.com

Re: [coreboot] What do each of the letters B...? , L...? , O...? , B...? represent in the acronym BLOB ?

(https://en.wikipedia.org/wiki/Blob) I think this definition transfers well to blobs in software, though. Without intrusive tools (a disassembler, etc.) you can't make out the structural details of a blob. Thanks, Jonathan

by John Lewis

I'm surprised anyone answered - you would think someone at a gnu address would already know what a BLOB is, and is therefore being rhetorical. :P On 31/05/17 09:16, Zoran Stojsavljevic wrote: > *BLOB*: *B*inary *L*arge *OB*ject. > > Zoran > > On Wed, May 31, 2017 at 9:57 AM, Don Saklad <dsaklad(a)gnu.org > <mailto:dsaklad@gnu.org>> wrote: > > What do each of the letters B...? , L...? , O...? , B...? represent in > the acronym BLOB ? > > > Paul Menzel <paulepanter(a)users.sourceforge.net > <mailto:paulepanter@users.sourceforge.net>> writes: > > [1:multipart/signed Hide] > > [1/1:text/plain Hide] > > Dear coreboot folks, > > I am looking for a new portable device available in Europe. > > Is it true, that the Acer Chromebook R 13 [1], is the only > current BLOB > > free device?
