			Elphel 393 series cameras can be equipped with m.2 SSD drive used for images and video recording. The camera equipped with a drive should be configured in a way that the drive can be accessible from Linux operating system. This is normally done with a configuration script which is executed during system boot. The script is located in the /etc/elphel393 directory and called ''init_elphel393.py''.

	Make sure this parameter is set to 1 if your camera is equipped with SSD drive.
