Okay, then it looks like I need to change my firmware version, but there I'm 
stuck. I went to this page:

http://wiki.laptop.org/go/Upgrading_firmware

which points me to this page to download the firmware:

http://dev.laptop.org/pub/firmware/

The latest firmware on that page seems to be q2e22, but there's no bootfw.zip 
file, the file it tells you to download, for that version, or for any version 
after q2d14. So should I downgrade the firmware to q2d14? I tried doing this, 
following the instructions, the the xo seems to ignore the firmware image. 
Looking at the boot information it says "firmware up to date", apparently the 
updgrade instructions don't work for downgrading firmware.

So I need to either downgrade the firmware, which I can't find instructions 
for, or install one of the versions newer than q2e18 which don't have 
bootfw.zip files, to do that I think I need to get a developer key and follow 
the manual firmware install instructions, so I've sent a request for a 
developer key and await the result.

http://wiki.laptop.org/go/Manual_Firmware_Install

Currently those instructions don't work for me, I hold down the escape key 
during boot but nothing happens, it just boots as normal, I guess that's 
because my xo is still secured, so I need to get a developer key and unsecure 
it.
