Hi,
I have just noticed a little mistake on http://wiki.archlinux.org/index.php/Official_Arch_Linux_Install_Guide#Archit...
It is written : "A Pentium II or AMD K6-2 processor or higher is required."
In fact, AMD K6 series (1, 2 & 3) are i586 CPUs (lack of cmov instruction to be qualified as i686). Arch is only installable on K7 (Athlon) or higher.
FWIW this is completely wrong. The i686 spec indicates cmov as an _optional_ instruction. It is GCC that fails here and makes it mandatory when it emits i686 optimized code. AMD K6 and Via C3 processors do NOT have the cmov instruction, but they're still i686 processors. GCC is the one at fault for this one
So in practice, do our binaries run on k6 and c3 cpus or not? I should probably add a note at the bottom that elaborates a bit on this subject. Dieter
