SCO Openserver System Release 5.0.7 

          The SCO OpenServer 5.0.7 Maintenance Pack 5 Release Notes 
          claim support for Hyper-Threading and Dual Core at:

          but I am unable to find the man pages online for "hyperthreading" or
          "dual-core".

          To make use of MuitiCore/Dual Core or Hyper-Threading on an 
          OpenServer 5.0.7 system you will need to: 
           
          1) Install the SCO OpenServer Symmetrical Multiprocessing 
          product from the OpenServer 5.0.7 Base Operating System 
          Installation CD. 
           
          Please Note: If you only have a single physical CPU on your 
          machine you can defer licensing. An SMP License is only 
          required for each additional physical CPU on your system. 
          Logical (Hyper threaded) CPUs do not require an SMP 
          License. 
           
          2) Install the SCO OpenServer 5.0.7 Maintenance Pack 5
          Images. You can get these images from: 
           
          http://www.sco.com/support/update/download/release.php?rid=186
           
          3) MultiCore and DualCore are enabled by default whereas Hyper-
             Threading is disabled by default. 
 
          To enable it, you can either edit your boot defbootstr with:

           "smp.ht=yes|no"
           "smp.mc=yes|no"
          
          or install without this functionality and add post-installtion in:
          
          /etc/default/boot  
           
          and add for HyperThreading:
           
          smp.ht=yes  
           
          to this file. 

          Multicore/Dual Core can be disabled with:

          smp.mc=no
           
          4) Reboot your system for the changes to take effect. 
           
          If you want to check on the status of your logical CPUs 
          once the  system has been rebooted type: 
           
          cpuonoff -c
