Custom Boot Command

If you select Custom boot command, preconfigured options will be placed on the kernel command line. This allows you for example to investigate and rectify problems with specific hardware components.

The Custom boot command is merely a temporary solution – it is not an everyday booting method. It must therefore be selected manually in the boot menu.

To configure the options for the Custom boot command, proceed as follows:

1. Open a local terminal and log in as root.

2. Enter the following command to bring up the current options:
   bootreg get /dev/igfdisk boot_cmd

3. Save your desired options with the following command:
   bootreg set /dev/igfdisk boot_cmd "<Your Options>"

4. Check the options that you have entered:
   bootreg get /dev/igfdisk boot_cmd

If you would like to delete options for the Custom boot command, leave an empty string of characters in their place: bootreg set /dev/igfdisk boot_cmd ""
