1Low-LevelTMSystem Configuration Module (cnfgdata) MICROWAREDirect Modification ProceduresTo modify the stand-alone module, complete the following steps:Step 1. Change to the CMDS/BOOTOBJS/ROM directory (see Figure 1-1).Step 2. Use EditMod to edit the module:$EditMod -e -dc_all cnfgdataTo modify the module as part of a merged module group, complete thefollowing steps:Step 1.Step 2.Step 3.Step 4.Step 5.Step 6.Step 7.Change to the BOOTS/SYSTEMS/PORTBOOT directory (see Figure1-2).Use EditMod to edit the module:$EditMod -e -dc_all cnfgdata -f=Use the menu selections provided in the EditMod LABELS section ofthe field reference later in this chapter to locate the fields you want toedit.Select a new value for the field from the AVAILABLE VALUES section ofthe field reference. Enter that value at the EditMod prompt to modify thefield.If you want to make additional modifications, use the p command(previous) to step backward through the EditMod menus. Repeat Steps3 and 4 until you have made all desired modifications to the cnfgdatamodule.Select the w command (write) to save the changes.Select the q command (quit) to exit EditMod.12 OS-9 Device Descriptor and Configuration Module Reference
