If you have already created an OS image and you have to modify-build-download it several times you can use a shortcut to perform those operations as fast as it is possible (if you do not add new components – which implies a sysgen): you can modify reginit.ini (for registry entries) and ce.bib (for files/modules to include in the OS image) then run from the command prompt:
regcomp %_FLATRELEASEDIR%\reginit.ini %_FLATRELEASEDIR%
The first command compresses the reginit.ini file to create some files which are included in the image in ce.bib:
If your OS image includes the hive-based registry the files are:
If your OS image includes the RAM-based registry the files are:
The second step processes ce.bib to create the new OS image. You can create a batch file which run the two commands and put it in your DEVELOPR (*) folder.
Be careful: everytime you run makeimg all your changes will be lost since reginit.ini and ce.bib will be rebuilt.
