Hi @ all,
is there a Coroboot for the Lenovo T410 Laptop?

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.
I have successfully ported coreboot to the relatively modern ASUS
KGPE-D16 server board (dual AMD socket G34, 16 DDR3 DIMMs,
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!
CPU: Dual AMD G34 Magny-Cours (Family 10h)
RAM: 16 DDR3 DIMM slots with ECC support (tested with x4 4G DDR3-1333
PCIe slots: all functional
PCI slot: functional
PS/2: expected to function, not tested (on SuperIO)
ASpeed VGA device: functional (text mode, see below)
On-board USB: functional
On-board NICs: functional
ASUS PIKE SAS controller: functional
PCIe ROMs: functional
DDR3 voltage set: functional
cbmem console: partial support (log truncated)
cbmem timestamps: functional
BIOS recovery jumper: functional
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!

I am new to this list.
I am trying to learn how to compile coreboot. My host has these:
---cpu: AMD64 3 cores
---OS: linux (BLFS) linux-3.10.32, ( pure 64-bit ), gcc-4.8.1. IASL (
downloaded as tbb41_201305160ss )
A ) I fetched coreboot fron the git repository
B ) I unpacked the downloaded in /usr/src
C ) I ran 'make menuconfig' and selected 'build with any toolchain'
D ) I then ran 'make' which ended as follows:-

i am trying to build coreboot according to
make crossgcc worked fine.
after running "make" im getting the following error and the building
process is stopped:
/coreboot/util/cbfstool/cbfs_image.c:451:59: error: comparison between
signed and unsigned integer expressions [-Werror=sign-compare]
assert((char*)CBFS_SUBHEADER(entry) - image->buffer.data ==
cc1: all warnings being treated as errors
make: *** [build/util/cbfstool/cbfs_image.o] Fehler 1
any ideas what is causing this error and how to fix it?
thanks in advance
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!! Can we see a video clip of that boot?

> The ME firmware that ships with Panther is 126.96.36.1996. I've also tested 188.8.131.524 (what I'm using in the firmware referenced above) and 184.108.40.2062 (which I just came across today) - all display the same behavior in terms of time needed to report MBP cleared. The 9.6 series ME firmware is also for Haswell/Lynxpoint, but I'm unsure if it's compatible with systems shipped with ME 9.5. Since I have an external programmer, I suppose I could always give it a try :) The 10.0 series ME firmware is for Broadwell and is more likely to contain the fix, but less likely to be compatible with Haswell/LP.
