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.

Re: [coreboot] Mohon Peak, Memtest86+ does not start
by Kuzmichev Viktor 20 Feb '15

Thank you very much, this helped a lot! Now memtest is loading and it successfully performs RAM tests. But there is another issue. Somehow, input via serial console does not work. And it seems like the problem is not in memtest, rather it's in SeaBIOS or coreboot. There is no any prompt for input in coreboot. But there is in SeaBIOS, and I was not able to enter boot menu since it did not respond to F12. Although, SeaBIOS responds to the keyboard that is directly connected to the board while memtest does not seem to respond at all (at least, I tried to hit Esc which should reboot the board). I've tried to search for this but so far found nothing. Will appreciate any help.

If harassment is the most common problem, that definitely warrants listing harassment first (which is not the case in the current CoC). > Defining > every other term would not make this policy any more robust. Is the term "harassment" so unclear it warrants explanation? I thought there was universal agreement that harassment is bad, but having to define harassment implies that there is no such universal agreement (you can't agree on something undefined). I argue that creating our own homegrown definition of harassment (or copying someone else's homegrown definition) makes this policy less robust because this current homegrown definition is woefully incomplete. >> Please define "community organizers".

[SOLVED] Read the Coreboot version in the .rom binary

Hi Patrick, Thanks for the tip and the related code snippet. It works like a charm. Best regards, Patrick Agrain Am 2015-01-28 15:39, schrieb Patrick Agrain: > Is there a way to read the coreboot version (as a string or as binary > chain) from inside the build coreboot.rom file. On x86, it's stored through src/arch/x86/lib/id.inc It's a somewhat arcane format (historically grown), and is typically ends 0x80 bytes before the end of the image. The last 4 qwords are the .long values from which you can calculate the address of the version field http://review.coreboot.org/gitweb?p=filo.git;a=blob;f=flashupdate/flashupda… test_id_section() and its caller provide an example for parsing that.
