+Storing `display.ini` is the preferred method to configure the descriptor file. If this is not possible or if the device has no filesystem, use one of the alternative methods:
 
 1. A `display.ini` file present in the flash file system. ***preferred option***
 2. A special `>d` section in scripting. Copy the file to the `>d` script section and place a `->displayreinit` cmd into `>B` section
