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.

#95: Run coreboot in VirtualBox

by coreboot

#95: Run coreboot in VirtualBox ---------------------------------+------------------------------------------ Reporter: uwe | Owner: somebody Type: defect | Status: new Priority: minor | Milestone: Component: misc | Version: Keywords: | Dependencies: Patchstatus: there is no patch | ---------------------------------+------------------------------------------ It would be nice if we could test coreboot images in VirtualBox, see http://virtualbox.org/. VirtualBox does not (yet) provide a simple mechanism to use a different BIOS in their emulated machines (something like "-L" in qemu). Instead the BIOS image (a custom bochs BIOS + LGPL'g VGABIOS) is converted to C code (an array of bytes, or the like) and merged into the VirtualBox executable. The relevant files are {{{ src/VBox/Devices/PC/DevPcBios.cpp bldprogs/bin2c.c }}} if someone want to hack VirtualBox to easily support using coreboot images instead of their usual BIOS. -- Ticket URL: <http://tracker.coreboot.org/trac/coreboot/ticket/95> coreboot <http://www.coreboot.org/>

Not true. Just do the same changes to the corresponding *.asl files in coreboot repo and send the patch to gerrit. Other than a layer of preprocessing, it's exactly the same code as you got from disassembly.

Re: [coreboot] coreboot Prague meeting - details

Hi Rudolf. Do you know from which time the hotel is accessible on Thursday? I just need to know if I can arrive at the hotel directly and leave my car there or if I should go to the university first.

I know the board comes with a socketed W25Q64FVAIG, although I'm having some trouble finding a distributor who carries that chip or equivalent chips. I assume the 80BV ones I have won't work, because they use a slightly different supply voltage range? -- Patrick "P. J."

ASUS F2A85-M questions

by Patrick 'P. J.' McDermott

Hi, I'm interested in running coreboot on the ASUS F2A85-M, and I have a few questions. The wiki page for the board says that hardware virtualization is untested. Has anyone tested this since the page was created in 2012? Or could someone with this board please test this? How reliable is the hack for supporting Richland CPUs? Are other variants of the F2A85-M (e.g. F2A85-M2) supported? -- Patrick "P. J." McDermott http://www.pehjota.net/ Lead Developer, ProteanOS http://www.proteanos.com/

AFAICS it's for FWH flash, a totally different beast. Or put another way, why would that register restrict SPI flash size in any way? Regards, Carl-Daniel

Re: [coreboot] sourcing 128MB flash chips for an X60 with coreboot

by ron minnich

FYI, at the coreboot workshop, thanks to the efforts of several people including peter, stefanct, and another person named "Ron's memory sucks", we got the u-root stuff working! This is a kernel and and an initramfs containing a full go toolchain and source to all programs that you run. They are compiled on demand. https://docs.google.com/presentation/d/1ji5hprsNFXmMBaYwLw0hphTItdSQs2chTq7… ron

Re: [coreboot] More Fn+key on X60T

Yeah so do you know how to do anything? How did you remapped Fn+Space at least?
