All K7 CPUs most emphatically *are* 686 CPUs, since they execute all the relevant Pentium Pro opcodes. > Also, > the k7 kernel is for 32 bit Athlon CPUs (which the amd64 is not). The K8 (in 32-bit mode) most assuredly *is* a K7. (What, you think AMD would break backward compatibility? That's the big draw of AMD64.) So, the AMD64 (in 32-bit mode) is a K7, and the K7 "is" 686, either kernel will work. > You > need a k8 kernel, specifically.

To get a 0.5% speed boost, use a k7-SMP kernel. - -- Ron Johnson, Jr. Jefferson LA USA Is "common sense" really valid? For example, it is "common sense" to white-power racists that whites are superior to blacks, and that those with brown skins are mud people. However, that "common sense" is obviously wrong. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.5 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFE9Uv2S9HxQb37XmcRAjR0AJ9PzEyKUjRNq+Y4RccGfWV3Wm0RXQCg7QxG DR0dHLoTs3UYbAnaj9kKIrw= =GXZ4 -----END PGP SIGNATURE----- -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
