Speedstep/Hyperthread with SCO

UNIX SCO
1

Hello,

I am running SCO Operserver 5.0.7 on a computer that has a Intel Duo core processor. The BIOS supports Intel Speedstep which is similar to Intel Hyperthreading and it is enabled.

In the boot file I added

ENABLE_HT=Y
ENABLE_JT=Y
HYPERTHREAD=Y

and in the space.c file I added

int crllry_multicore_enable = 1;
in crllry_hyperthread_enable =1;

I then run link_unix to rebuild everything and reboot, but still only see 2 CPUs and not 4. :cool:

Any help would be greatly appreciated. :slight_smile:

Thanks,

Ernie
