Hi Daniel Thanks for the input. The XO is booting fine after the firmware update.
I was looking for the bootfw.zip online, older released firmware versions have the bootfw.zip in this directory: http://dev.laptop.org/pub/firmware/q2e18/ But you are right, I can just copy the bootfw.zip from a working XO with build 767 installed. The ticket 7607 got fixed with q2e12 so it shouldn't happen with build 767 (q2e18) anymore. But I got the information that 3 XOs with build 767 had the same problem. They got fixed with a clean install, so no way for further diagnosis.
