Not all i586-CPUs have MMX, so I'm not sure if the kernel would use MMX in i586-mode (despite for runtime-mmx-detection, but this option you can have without march=i586). And you are always free to a) compile a kernel with march=i586 b) use mmx in your favorite userland application Dirk. -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
