Two quick one for kernel and/or compiler wizards: first, is a 400Mz processor considered a 586 (for my KERNELCONF file)? Second, is it safe to do a buildworld with -O3? If there are stability concerns, I'll go with the default when I rebuild my 6.2 systems. thanks in advance, gary -- Gary Kline kline at thought.org www.thought.org Public Service Unix
