And it was all a bogus trail.. It's *timer* related! I made start_rtc_timer() fail (return -1) unconditionally, and voila it boots first time every time, and any Image I throw at it.. So something in the win2k loader appears to be timing sensitive. I did try the -win2k-hack for a lark, but that only had random results.. So there is an issue with the RTC handler on this machine by the looks.. RTC max freq is 1024, so it's not that.. further debugging required Regards, Brad -- "Human beings, who are almost unique in having the ability to learn from the experience of others, are also remarkable for their apparent disinclination to do so." -- Douglas Adams
