[SeaBIOS] Chromebook doesn't boot BSD

[Ronny Schneider]

Hello there,

i have a Toshiba Chromebook 2 (CB30-B-104) with a flashed on SeaBIOS by the script from John Lewis: https://johnlewis.ie/custom-chromebook-firmware/rom-download/

Linux is running very well but i want to see OpenBSD 5.8 on this laptop. But it’s not working, neither do FreeBSD 10.2, NetBSD 7.0 or DragonFly 4.2. The boot stops at the point where the kernel wants to mount the root-filesystem. I even copied an installed OpenBSD-System from an usb-stick onto the emmc-flash of the chromebook but it’s not working.

I googled arround and found out the problem is not unknown among the Chromebook Pixel. So i thought i could help a little by providing my cbmem-bootlog for my machine: http://pastebin.com/asLqar5q
If i can do more to see OpenBSD booting on this laptop, please let me know :-)

Thank you very much!
Greetings,
