In fact, www.Powerleap.com will sell you an accellerator for your UP P-Pro machine using a coppermine celeron processor past 700 MHz, and a PPGA celeron up to 533 MHz for Dual processor systems. So, as long as i686 optimization doesn't include MMX, etc, I think making the SMP kernels i686 optimized is a good move. I think i486 had better SMP support than classic Pentium, and none of the Pentium clones had any. Best Regards, Chuck Shirley
