XO boot problem

[Philipp Kocher]

Hi,

An other school in Cambodia has the problem that several XOs don't boot 
anymore. Some of the XOs have build 708 and other ones build 767 
installed. All are in secure mode.
With a dignostic startup the following information is last shown on the 
screen:
OLPC C2, 256 MiB memory installed, S/N CSN75001163
OpenFirmware CL1 Q2D16 Q2D

Nothing happens anymore afterwards.

The OFW hardware diagnostic is still working.
After a clean install the XO works fine again but all the data is lost.

Has anyone a solution for that problem or input for further diagnosis?

I wanted to recommend a firmware update, but the file bootfw.zip is 
missing in the directory for the newer firmware releases (e.g. q2e18 for 
build 767):
