Hi, I have 2 of these running dual p2-450 cpus, the problem is on neither machine cat /proc/cpuinfo shows the second cpu, ive swapped the cpu's about and booted with 1 cpu at at time and the server still boots so this suggests the hardware / cpus are fine. anybody know a fix? Im using standard smp debian kernels, eg apt-get install kernel-image-2.4.18-686-smp So im a bit stumped. regards Steven
