UEFI Shell Script Auto-Start configuration in the System Utilities

The startup script enables you to create a RAM disk, download files from the network, collect data, upload results back to network, and then boot to the OS without rebooting the system. You can store the script file on local media, or access it from a network location.

By default, UEFI Shell Script Auto-Start is enabled in the System Utilities and is configured so that the Shell looks for the startup.nsh file in any FAT16 or FAT32 file systems available. You can modify these settings so that the Shell looks for the startup script in a specific file system on attached media, or in a specific network location. When configured for a network location, you can specify the URL in HTTP or FTP format of the startup.nsh file location.
