All,
After reviewing some of the comments on the ASUS KGPE-D16 being
essentially too large of a system and too expensive for many people, and
the fact that modern, blob-free systems are not really available in the
mid-range arena, Raptor Engineering would like to offer to create a
native initalization blob-free port for the ASUS KCMA-D8, which is
essentially the KGPE-D16's ATX-compatible "little brother".
We would be asking $15,000 for the port, including upstreaming to the
master coreboot tree. We already have extensive experience with these
Family 10h/15h boards, and would be able to create a port of similar
quality to the existing KGPE-D16 source in terms of both code quality
and overall functionality.
If this is something you might be interested in please let me know. We
are able to accept multiple payments from various sources for the same
project (within limits), so if this is something your local Linux groups
or similar might be interested in we should be able to keep the cost on
any one individual or organization to a reasonable level.
Thank you for your consideration,
- --

Hi John,

Thank you for the hint. I inspected that, but the PCI-IDs actually look the same:
00:01.0 VGA compatible controller [0300]: Advanced Micro Devices, Inc. [AMD/ATI] Trinity [Radeon HD 7480D] [1002:9993]
(A4-5300)
and
00:01.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Richland [Radeon HD 8670D] (prog-if 00 [VGA controller])
(A10-6700)
Looks like the VGA BIOS is really different:
# diff vgabios_a4-5300.bin vgabios_a10_6700.bin
Binary files vgabios_a4-5300.bin and vgabios_a10_6700.bin differ
Guess I will have to to "update" the VGA BIOS then.
Cheers, Daniel

However, I did not get any video output when trying to boot after the upgrade, so I replaced the flash chip with a backup with the vendor BIOS that works.

The Linux 4.7 kernel payload crashes early in the boot process
with CoreBoot 4.4. I traced it to these instructions that are
finding a safe spot to decompress the rest of the kernel and
patched around it with a hard coded location:

It seems that the Linux kernel bzImage is supposed to set this value,
rather than coreboot, so my comment is likely incorrect.
Dumping linux-4.7/arch/x86/boot/header.o, it looks like init_siez
is supposed to be 0xcf5000, so I wonder if %rsi is pointing to the
wrong location.
In 4.6.4 the computed address was hardcoded:

Hi,
FOSDEM 2017 deadlines are soon.
Do we want to have a full developer room, a talk or just a stand?
Unfortunately I won't be able to attend, so someone else will have to be
the formal contact for organizing our stand/devroom/talk. I will help
with submitting proposals if this is desired by the person organizing
our stand/devroom/...
Who is willing to take care of our FOSDEM 2017 presence?
https://fosdem.org/2017/news/2016-07-20-call-for-participation/
Deadlines:
Developer Rooms: 9 September
Main Track Talks: 10 October
Stands: 31 October
Lightning talks: 25 November

How stable is the i7-3720qm CPU Upgrade in the t420? You guys have it listed under the tested portion. I want to grab myself one, but would want to see if it's worth my time to upgrade the CPU, or just go with something more powerful.
> If you have any other reading material on the entire process I would love

I will be not able to comply to entire process, but here is a bit more... I
guess, important below:
(finding CPUID [CPUID 0x306A9 (SR0MM)] on the following www page):
http://www.cpu-world.com/CPUs/Core_i7/Intel-Core%20i7-3720QM%20(BGA)%20Mobi…
Then, please, read this, in order to determine the latest MCU (seems
microcode-m12306a9_00000019):

Good Luck! :-)

Hello Mayuri,
I am not mistaken, RMT stands for Rank Margin Tool (related to DDR3/DDR4):
http://www.freepatentsonline.com/7689879.pdf
I am afraid, actually, the fastest/only way for you is to contact INTEL
support.
Good luck with that. You'll certainly need it!? ;-)

Hi Team
I am exploring usage of Intel memory related tools with coreboot for Intel BayTrail processors.
As per their guide, it works on Valley View BIOS with some MRC settings.
Has anybody explored on this?
