hi, under 3.4: # sysctl -a |grep freq kern.acct_chkfreq: 15 machdep.i8254_freq: 1193182 machdep.tsc_freq: 551252612 under 4.3: # sysctl -a |grep freq kern.acct_chkfreq: 15 machdep.i8254_freq: 1193182 i guess it's out. if it's renamed i'll appreciate if someone share that info ;-) here. alex p.s. my english sux. sry for spelling and stuff On Mon, 30 Jul 2001, Jim Freeze wrote: > On Mon, 30 Jul 2001, Alexander V P wrote: > > > hi, > > i've compiled and it didn't work. error:sysctlbyname(): Operation not > > supported > > any idea? > > tia, > > alex > > > > I have not tried to compile this on 4.3.
