+Centos4 IS NOT a modern distro. It is a LTS started in 2005 and so it
+maintains 2005's original skeleton of kernel, gcc, glibc and X. That's FIVE
+years old. As example MDV 2007.1, which is 3 years old, was still very
+usable and responsive on my P4/ATI (maybe not as much as stable with 3D
+acceleration), but 2010.0 ISN'T.

+I don't want to deprive the fun of building a router or a firewall from an
+old P133/64 with two ethernet cards, or some mediabox, but often you can't
+(and sometimes you pay of energy power in a year much more than getting some
+30-50E linksys ARM linux based router. And when soemone try such kind of
+attempts in the real world with your distro, will be very disappointed of
+failures. That's why I in some way asked a survey of oldest hardware based
+on own experiences.

+Very interesting, but will such "industrial use" will be target for Mageia
+(BTW, certainly socket 775 CPU will support SSE and SSE2...)? If they have
+an ISA slot, I guess is for maintaning the compatibility with some old fancy
+(and maybe custom) card, certainly not for an ISA ethernet card that can be
+easily replaced with a cheap PCI one or the one on board.

+Not exactly. I'm not talking in just using -march=<something> but in also
+pushing -mfpmath=sse -msse (and maybe -msse2) , which should be much more
+than JUST 1-2% (1-2% is usually the benchmark tolerance)...Indeed the
+original idea was of having real .i586, .k6, .k7.rpm, .viac3, .viac7.rpm RPM
+packages, at least for the core ones: some time ago, when I was fighting
+with having a non-crashing kernel for the dedibox, I had started adding such
+"dialects" to the RPM macros (but problems were on the glibc package), but
+being realistic I think it's a lot of work and there aren't the resources,
+so a choice of the default flags should be done.
+
+Bye
+Giuseppe.
