I noticed that http://dcs.ex.ac.uk/~aba/percent.html was reporting: Percentage complete PERCENTAGE COMPLETE 4094 / 4096 = 100.6 percent which looked a bit odd to me :-) Do I detect a Pentium at work ?? Anyway, I grabbed a 29 bit address space and got: ffe0000000 29 THATS IT FOLKS! ALL DONE! and now it reports: Percentage complete PERCENTAGE COMPLETE 4096 / 4096 = 100.7 percent
