------------------------------------------- model name : Pentium II (Deschutes) stepping : 2 $ ./syse Segmentation fault ------------------------------------------- model name : Celeron (Mendocino) stepping : 0 cpu MHz : 334.097 $ ./syse Segmentation fault ------------------------------------------- CPU: Pentium II/Pentium II Xeon/Celeron (299.94-MHz 686-class CPU) Origin = "GenuineIntel" Id = 0x651 Stepping = 1 $ ./syse Bus error (core dumped) -------------------------------------------
