Another poster has sent me a memory testing program which I will try tonight in the early hours. With 1 CPU enabled the box is completely stable. There are no memory errors of any kind and all is fine. Tonight I will enable the second CPU again and see if I can find out more infomation... Could it be that a memory fault only occurr when the second CPU is enabled (ie: when Option SMP and option APIC_IO is enabled in the kernel)?
