Using CPUTYPE=i686/pentium2 resulted in the bootloader and the kernel containing instructions which the CPU couldn't handle (ie, the system halted and panic'ed) when I tried. I believe you could use CPUTYPE=pentiumpro or pentium-mmx OK, but there didn't seem to be any performance difference, and I'm leery of chasing the compiler optimizer too far when it doesn't change the system performance by a noticable amount. -- -Chuck
