uEFI Shell Scripting
6.6.1.
Startup Scripting
If the <ESC> key is not pressed and the timeout has run out, then the uEFI Shell automatically tries to execute some
startup scripts. The UEFI shell searches for scripts and executes them in the following order:
1.
Initially searches for Kontron flash-stored startup script.
2.
If there is no Kontron flash-stored startup script present, then the uEFI-specified startup.nsh script is used. This
script must be located on the root of any of the attached FAT formatted disk drive.
3.
If none of the startup scripts are present or the startup script terminates then the default boot order is continued.
6.6.2.
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 the root of any FAT-formatted drive attached to the
system. To copy the startup script to the flash, use the kBootScript 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 SPI
boot flash using the kRamdisk uEFI Shell command.
6.6.3.
Example of Startup Scripts
6.6.3.1.
Execute Shell Script on other Harddrive
This example (startup.nsh) executes the shell script named bootme.nsh located in the root of the first detected disc
drive (fs0).
fs0:
bootme.nsh
