Well 1. $prefix must be set correctly (normally is done for you by grub-install & Co.; I do not know how you created your image) 2. Device which is part of $prefix must of course exist. You may need to explicitly load partition driver (not autoloaded) and/or virtual storage drivers (Linux MD, LVM2, LUKS, etc) 3. You need filesystem driver for this device (normally autoloaded). 4. Most vendors build images for use with Secure Boot that disable module load. Unless module is included in the image by vendor, it is flat unavailable. If you are using such image (you most likely do if you enabled secure boot support in your OS configuration) - check how image is built. You are using openSUSE, are not you? All of this is basic stuff and has nothing to do with your problem with serial port. _______________________________________________ Help-grub mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-grub
