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] 'power on after fail' on Panther (Haswell/Lynxpoint)

Currently, the box will power on if AC power is lost and the device was powered on, but not if powered off. I have a use case where it would be convenient to be able to power on the boxes by toggling AC power (eg, the boxes are not within physical reach). I modified the CMOS default setting for 'power_on_after_fail' to be enabled and verified its status with nvramtool. I also tried modifying lpc.c/smihandler.c in the southbridge code to force MAINBOARD_POWER_ON (rather than MAINBOARD_POWER_KEEP) in all cases, to no avail. > > Am I approaching this from the wrong angle, or is it perhaps not possible with these boxes? > > > > This might be due to the SuperIO instead of the Southbridge. Panther does call it8772f_ac_resume_southbridge() which *should* be making the southbridge the one responsible for the power behavior when AC is applied, but as a first test you could try removing that call to see if the default SuperIO behavior is closer to what you want. Hi Duncan, I tried removing the call as suggested, but it didn't change the behavior at all. Any thoughts as to where to look next? thanks! -Matt > > -duncan >

memtest86 reading 0k memory

by Timothy Pearson

All, I have a board here that loads memtest86 but won't actually test memory. This is the output: Memtest86+ v2.11 AMD K10 CPU @ 2312 MHz L1 Cache: 64K 35028 MB/s L2 Cache: 512K 6963 MB/s L3 Cache: 2048K 6052 MB/s Memory : 0K |------------------------------------------------- Chipset : 0K LinuxBIOS I'm guessing memtest86 doesn't understand coreboot's memory tables/structure, but I have no idea why that would be. The e820 map is valid: e820: BIOS-provided physical RAM map: BIOS-e820: [mem 0x0000000000000000-0x000000000009fbff] usable BIOS-e820: [mem 0x000000000009fc00-0x000000000009ffff] reserved BIOS-e820: [mem 0x00000000000f0000-0x00000000000fffff] reserved BIOS-e820: [mem 0x0000000000100000-0x000000003ffacfff] usable BIOS-e820: [mem 0x000000003ffad000-0x000000003fffffff] reserved BIOS-e820: [mem 0x00000000e0000000-0x00000000efffffff] reserved Any ideas?

Re: [coreboot] Coreboot reproducible builds

by Alexander Couzens

Hi Emilian, I chatted today with Holger from reproducible.debian.net and couldn't resist doing reproducible builds ;). These patches need additonal work, but they are working when the git tree is clean. You can test coreboot reproducible when building without payload. Or a more advanced way integrate my seabios git-tree into coreboot's payload target. coreboot needs 2 patches (one is very dirty ;) to build reproducible. http://review.coreboot.org/#/c/8611/ http://review.coreboot.org/#/c/8612/ SeaBIOS requires one patch. https://github.com/lynxis/seabios/commit/487ef74fc6cb1b1020fb25c9bb3f166602… Best, lynxis

Re: [coreboot] VGA doesn't work on Mohon Peak

by Kuzmichev Viktor

I tried not to include any VBIOS file in coreboot ROM much earlier, in my first tests. With 'Run VGA Option ROMs' option checked the board just hung. And as I mentioned in my previous email VGA works fine with vendor's BIOS. So the card itself should be fine. Sadly, I don't have another card to try. Even if I had, I still would need to make this one work somehow as Mohon Peak is just a reference board and the target board will have a similar VGA controller. So please, let me know if there are some other things I could try or if I am mistaken somewhere. -Viktor On 03/19/2015 09:20 PM, Marc Jones wrote: > > Hi Viktor, > > On Thu, Mar 19, 2015 at 4:23 AM Kuzmichev Viktor > <kuzmichevviktorv(a)gmail.com <mailto:kuzmichevviktorv@gmail.com>> wrote: > > Hello, > > I'm using coreboot + SeaBIOS on Mohon Peak CRB.

Re: [coreboot] Question on VGA BIOS extraction

by WANG FEI

TP X220 suppose to have a UEFI compatible BIOS, is it possible it has a UEFI DXE VGA driver (not sure what's the proper name of it) except a legacy video? Maybe you should boot up system with original BIOS and check the content in 0xC000 segment, is it a legacy VBIOS or it's empty...

Question on VGA BIOS extraction

by Iru Cai

Hi, I'm trying to build Coreboot for ThinkPad X220. I first backup the vendor BIOS, then use UEFITool to extract a VBIOS. The romheader program detects the ROM's PCI data structure and reports the device id is 8086:0106, but the VGA controller's device id is 8086:0126. I extracted the video ROM from a running X220 memory and use romheader to test it, the result is still 8086:0106. How could this happen? Iru
