i was reading locore.s and noticed that the T_CPEXCEPTION and T_CPDISABLED traps are in the wrong place in the trap table. T_CPDISABLED is in the slot for trap 0x36 (should be 0x24 (decimal 36)) T_CPEXCEPTION is in the slot for trap 0x40 (should be 0x28 (decimal 40)) -- matt@rme.com http://www.rme.com/
