Richard, Sorry.
1) I knew about the separate memory for the firmware. I've reloaded it often enough :-). I was more interested in publishing that thinking deeply about how the XO works. 2) Again, sorry about my loose use of language. I should know better, and try to be more precise. However, my understanding of the OF V2 is that it incorporates the legacy behavior of the underlying BIOS of a MS/DOS-Win machine, which is it's critical (at least for this issue) difference from OF V1. But my point stands; the MS demo machine is single boot, and ignores the flash and its contents. This would be a very bad thing to let out of the lab. >> I just saw the Microsoft video of an XO running XP. In it the XO >> single boots from an 'insyde' BIOS.
