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] 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. Cheers, lynxis -- Alexander Couzens mail: lynxis(a)fe80.eu jabber: lynxis(a)jabber.ccc.de mobile: +4915123277221

coreboot ported to the ASUS KGPE-D16 (Libreboot: blobless, fully functional!)
by Timothy Pearson 17 Oct '15

17 Oct '15

All, I have successfully ported coreboot to the relatively modern ASUS KGPE-D16 server board (dual AMD socket G34, 16 DDR3 DIMMs, https://www.asus.com/us/Commercial_Servers_Workstations/KGPED16/)! This port uses native Family 10h initialization (_not_ AGESA or CIMX). The Libreboot folks will be interested to know that this board can run blob-free and still retain full functionality! Port specifications: CPU: Dual AMD G34 Magny-Cours (Family 10h) RAM: 16 DDR3 DIMM slots with ECC support (tested with x4 4G DDR3-1333 unbuffered DIMMs) Peripherals: PCIe slots: all functional PCI slot: functional RS-232: functional PS/2: expected to function, not tested (on SuperIO) ASpeed VGA device: functional (text mode, see below) IEEE1394: functional On-board USB: functional On-board NICs: functional ASUS PIKE SAS controller: functional PCIe ROMs: functional Power management: DDR3 voltage set: functional ACPI/APIC: functional Suspend/resume: broken Other: cbmem console: partial support (log truncated) cbmem timestamps: functional nvram: functional BIOS recovery jumper: functional ASpeed VGA: The ASpeed VGA device initialises in text mode via its (new) coreboot driver, however this initialisation is incomplete, leading to distorted but quite usable VGA output. When Linux boots and engages the graphical framebuffer all distortion disappears. This port was not trivial. Almost every device used was broken and required debugging/repair, with the notable exception of the SuperIO chip. The AMD DDR3 controller was severely broken to the point where large rewrites were needed in order to bring it in line with the BKDG. Even after the various component drivers were repaired Due to the labor-intensive nature of the port and the extensive changes throughout the entire source tree, it is not economically feasible to merge this port upstream at this time (I estimate upward of 30 independent patches would be required just to get the board booting!). Raptor Engineering will, however, be continuing to maintain this port internally, and I am currently looking into adding native Family 15h support on top of this internal tree. Additionally, while it was not a priority for the initial port, I will be attempting to enable suspend/resume functionality as I have time. If there is sufficient interest from the community in adding this board to coreboot I would consider merging the changes in exchange for a one-time contract payment in the vicinity of $35,000 USD. When considering this offer please bear in mind that this is a fully functional blobless board with a wide range of peripherals and expansion options available, and that once these large changes are merged I will continue to enhance coreboot functionality as before (e.g. with the KFSN4-DRE and the T400). I would also be willing to add this board to the test stand as the only fully supported 4-way Opteron board (socket G34 Magny-Cours CPUs contain two separate CPUs in one package, making this 2-socket board a 4-way system from a HyperTransport perspective). Please let me know if you have any questions! -- Timothy Pearson Raptor Engineering +1 (415) 727-8645 http://www.raptorengineeringinc.com

[Mohon Peak] Memtest86+

Hello, I try to perform some memory test on the Mohon Peak CRB with memtest86+. I downloaded memtest86+ v5.01 and compile it. So far, so good.

Re: [coreboot] Google Panther: coreboot has to wait for Intel’s ME (Management Engine)

That’s truly amazing! So the FSP + coreboot part only takes a quarter of a second? Intel FSP must be on steroids!! The total boot time is the sum of components time, so if you fix that problem you will have close to a quarter of second boot time!!
