If you _are_ changing processor types (like from a 486/Cyrix MediaGX to a Pentium/K6/K6-2/Cyrix, or a Pentium/K6/K6-2 to a Pentium II/Pentium III/Xeon), then you need to make sure you have one of the lines: cpu "I586_CPU" cpu "I686_CPU" You could just recompile a kernel with both of those lines (and a line for a 486, if that's what you have now). It doesn't hurt to have the lines and not have the CPU (except maybe that the kernel eats up a bit more disk and RAM). But if you don't have the proper cpu line, then your kernel won't boot. --Ludwig Pummer <ludwigp@bigfoot.com> To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
