Hi Sathvik, Is Speedstep enabled in your BIOS?
I suspect your live CD is OpenSolaris 2008.05? That should have Speedstep support? It looks like Speedstep support integrated in July of 2007: http://opensolaris.org/os/community/on/flag-days/pages/2007071601/ Regards, Bill On 12/19/08 12:38, sathvik L wrote: > Hi Bill , > > Dec 18 01:33:29 belenix unix: [ID 950921 kern.notice] cpu0: x86 > (GenuineIntel F33 family 15 model 3 step 3 clock 2400 MHz) > > This line (or from "kstat -m cpu_info") says that family = 15 (0xF) > and model = 3 So this criterion > > if (!((family == 0xf && model >= 0x3) || > (family == 0x6 && model >= 0xe))) { > return (B_FALSE); > } > > gets satisfied from speedstep.c. > > Was the cpudrv drviver present in the kernel version 5.11 ?
