At which stage do you want to enables these ports? in the OS? or during
boot? if the latter, which payload do you use?
Zheng: I want to enable these display port during boot. The payload is SeaBIOS.

Do we have any idea what exactly they do to update the firmware internally?
The wiki says once coreboot is flashed you can flash it internally. I
suppose this means the blockade protecting the flash can be switched of
somehow, as the vendor's have to do it to install firmware-updates.

Though I wonder when and how they programmed the firmware. Before or
after soldering?

Hi Philipp,
It is just a wson-8 flash rom, whose soldering plates are compatible
with those for soic-8 chips, often found on thinkpads produced when 8MiB
soic-8 chip are hardly available.
The common way to deal with wson-8 chips is to blow it off with hot air
blower, suck up its content, and fina

in the akaros virtual machine code, we set up a simple 1:1 map and start
linux at the 64-bit entry point, at which point it builds its own page
tables. So entering a payload in long mode is certainly possible and IMHO
ought to be the standard on amd64 -- not that anyone cares what I think
anyway :-

Howdy,
In your config file you have:
# CONFIG_VGA_BIOS is not set
in coreboot, which will mean that coreboot doesn't setup the display,
but in your SeaBIOS config you have:
CONFIG_SEABIOS_VGA_COREBOOT=y
which will try to reuse whatever coreboot has setup. So as you might
understand, this c

I need to clarify my question.
For Broadwell-U, are there internal 3 display ports? Is the first one set

the first (DDI0 or DDI-A) is eDP only. The other two can be used for DP,
HDMI/DVI or both (aka DP++ or dual-mode DP). Wha
