Sh CreatePersistentImg.sh -> persistence.dat in 1GB size and ext4 filesystem and casper-rw label I have provided a CreatePersistentImg.sh script here.ĭownload it and just run sudo bash CreatePersistentImg.sh in the linux shell, by default a persistence.dat file will be created with size=1GB fs=ext4 label=casper-rw. If you don't want to use the pre-created file and want to create it by yourself.

You can download pre-created image files from Create by yourself You can directly download the pre-created image files or create it by yourself. The backend image file is a disk image with a label. Please refer Multi-Mode Option for details. You can set different configurations for different BIOS mode.

If autosel not exist, it's the same as it set equal to 0. If autosel exist, then the corresponding menu item will be used and the prompt menu will NOT be popped up anymore. Prompt menu will be popped up, the default selected menu item is as described above, no timeout, will wait for user selection all the time. Prompt menu will be popped up, the default selected menu item is as described above, when timeout the corresponding menu item will be selected. Optional, if you set it, the value must be greater than or equal to 0 If not set, default is 1.Ġ: boot without persistence backend image fileġ: boot with the 1st persistence backend image fileĢ: boot with the 2nd persistence backend image fileģ: boot with the 3rd persistence backend image file If you set it, that means you auto select the corresponding option in the prompt menu.
