uEFI Shell Scripting
6.3.1
Startup Scripting
If the ESC key is not pressed and the timeout is run out, the uEFI Shell tries to execute some
startup scripts automatically. It searches for scripts and executes them in the following order:
1. Kontron flash-stored startup script
2. If there is no Kontron flash-stored startup script present, the uEFI-specified startup.nsh
script is used. This script must be located on any of the attached FAT formatted disk drives
under \efi\boot\startup.nsh.
3. If none of the startup scripts is present or the startup script terminates, the default boot
order is continued.
6.3.2
Create a Startup Script
Startup scripts can be created using the uEFI Shell built-in editor edit or under any OS with a
plain text editor of your choice. To create a startup shell script, simply save the script on any
FAT-formatted drive attached to the system under the file name \efi\boot\startup.nsh.
To copy the startup script to the flash use the kbootnsh uEFI Shell command.
In case there is no mass storage device attached, the startup script can be generated in a RAM
disk and stored in the flash bank.

Automatic Booting from USB Flash Drive
Automatic booting is made from a USB flash drive, if present, otherwise the boot is made from
the harddrive.
If neither a USB flash drive nor a harddrive is present, the boot order is continued.
