Well, I only had a quick look and this might be a good way to measure the clock speed. BTW, can you please make sure you use our coding style? Are the 2-3 loops based on some calculations or only a guess? There might be a problem with using this instruction. Are clock cycles actually measured after using the "halt" instruction? If not, the use of such instruction might not generally used in GRUB :-/ -- Marco _______________________________________________ Grub-devel mailing list Grub-devel@gnu.org http://lists.gnu.org/mailman/listinfo/grub-devel
