   i found a strange case, i have tested the three machines(PIII 800 & 
P4-1.6G & FreeBSD4.8-release, P4-2.0G & FreeBSD5.2.1).
   I use "sysctl -a | grep machdep.tsc.freq" to get the CUP speed. But, I 
failed on the P4-1.6G machine. Nothing appears.
  Should I set some additional stuff on the P4-1.6G machine? I have do 
nothing specailly for the other two machines, but it works.

Best Regards
