Alexander - I would guess your referring to this line: # groups of related archs %define all_x86 i586 i686 so either i586 or i686 would be the correct choice for a pentium M processor? I've found lot's of refrences that explain that you need to cosse one but nothing that explains the criterion on which that decision should be made. i should copy the patch into sources before the rpm build? thanks, Jeff
