Aaaaaand... #systemrescuecd can also #webboot \o/

This time I've sped up the video instead of cutting out the lengthy bits. It's still horribly slow in QEMU, so just wait the one minute for it. :)

I am slowly getting behind mkinitcpio's hooks. So #Manjaro, you're next! :)

Here is the recording of my talk on the #IntelME:

Amd sorry, my timing was bad, so this was mostly focusing on platform basics to get into the field. I will do better again at @fosdem in the Open Source #Firmware devroom, I promise!

Big thanks to @west for the great stage! \o/

The recordings of this year's #Open Source #Firmware Conference are now online, finally. :) Playlists are available. \o/

My #preferences in a nutshell.

Finally, here is the #demo I had hacked into #coreboot + #SeaBIOS and released at Revision 2019. \o/

This is nice. :-)

Do you see the unpopulated solder joints next to the red marker?

This is another board. I measured 1kOhm on the resistors that are on the board in the first picture. I can just bridge the joints to get the UART here as well. :)

This board actually has the components soldered for the UART. :-)

I am only getting output from U-Boot though.

This doesn't even look suspicious after reassembly.

Quite some time later now, Intel have published their whitepaper: https://www.intel.com/content/dam/www/public/us/en/security-advisory/documents/intel-csme-security-white-paper.pdf

Such a simple idea, though it took a while for me to have it: If you have no #password to log into an #embedded #Linux, but you do have UART and U-Boot access, add "single" to the kernel command line.
The SPI programmer couldn't read the flash in-system. Dumping /dev/mtd* to an SD card is easy.
In the next step, I will copy out the modules for wi-fi and build a u-root image ready to chroot into. That is something for next week though. I am already satisfied and happy with this achievement. \o/
