Is there a way to turn this on? Alt, in what file is this string, so I can try without it. Please teach your mail program to wrap lines around column 70-72. thanks. That string is located in arch/x86/Makefile: # prevent gcc from generating any FP code by mistake KBUILD_CFLAGS += $(call cc-option,-mno-sse -mno-mmx -mno-sse2 -mno-3dnow,) KBUILD_CFLAGS += $(call cc-option,-mno-avx,) -- ~Randy
