1. Create  the $IOC_DATA directory for your cpu and iocs  as follows:
1. cd $IOC_DATA
2. mkdir cpu-<area>-<subsystem-prefix><2-digit#>
3. mkdir  sioc-<area>-<subsystem-prefix><2-digit#>
1. cd sioc-<area>-<subsystem-prefix><2-digit#>
2. mkdir autossave autosave-req iocInfor archive restore
   
2.  Create the $EPICS_IOCS cpu and ioc boot directories
1. cd $EPICS_IOCS
2. mkdir cpu-<area>-<subsystem-prefix><2-digit#>  
   1. cd cpu-<area>-<subsystem-prefix><2-digit#>
   2. Setup relative symbolic links to the common startup script and EPICS version:.
      1. ln -s ../common/st.cmd.linuxRT.cpu startup.cmd
      2. ln -s ../common/bin/<epics base version> epicsSpecificRelease
   3. Generate a Generate the file kernel-module.cmd. This file load kernels modules and drivers: kernel-modules.cmd file
      1. for examples click  here.
3. mkdir  sioc-<area>-<subsystem-prefix><2-digit#>
   1. cd sioc-<area>-<subsystem-prefix><2-digit#>
   2. cp ../template/st.cmd.linuxRT startup.cmd
   3. edit startup.cmd and replace <ioc> with your ioc name.
   4. cp ../template/screenrc and replace <ioc> with your ioc name.
   5. edit screenrc and replace <ioc> with your ioc name.
   6. Please note that if the location of your IOC Application st.cmd file is non-standard then change EPICS_IOC_APP path in startup.cmd
   7. Setup a relative symbolic link to the TOP of the IOC Application release
      1. ln -s ../../iocTop/<app>/<version> iocSpecificRelease
4. Add cpu and IOC to $EPICS_IOCS/screeniocs   
1. Please note that the  $EPICS file is a symbolic link, so cd to the appropriate directory and edit this file
2. add line for cpu
   format:  cpu-<area>-<subsystem-prefix><2-digit #>      <ts>   <ts port #t>   <screen  host>   [ # comment]
3. add line for each ioc
   format:  sioc-<area>-<subsystem prefix><2-digit #>  cpu-<area>-<subsystem-prefix><2-digit #>    <account>   [ # comment]
4. The "comment" field in screeeniocsis optional and must be precede but  "#".
   

3. IOC Applications with RT constraints:

1. Create script <app>/iocBoot/<ioc>/rtPriortiesSetup.cmd  to set real-time priorities for threads
2. Load rtPriortiesSetup.cmd from <app>/iocBoot/<ioc>/st.cmd
