Instead of manually running +cbfstool to manipulate these configuration files, this script will handle the +work for you so you can focus on actually modifying your GRUB configuration +files to your setup's needs. + +At the time of this writing, grubeditor.sh supports extracting and editing +either the grub.cfg or grubtest.cfg file in any cbfstool-compatible Libreboot +ROM image that contains these files, even ones that have been previously +modified. It can also swap these configuration files in an existing ROM image, +handy if you have a working grubtest.cfg and want to make it the default or if +you broke the main grub.cfg and know that your grubtest.cfg still works. Lastly, +it can also run diff on these two configuration files to show you how they +differ. + +## Requirements + +grubeditor.sh requires an x86, x86\_64, or armv7l environment, since these are +the environments for which cbfstools binaries are provided. Additionally, +grubeditor.sh needs a Bash environment with extended getopt functionality that +can run the **diff** command and write to /tmp. Lastly, the script expects to +live in the top directory of the Libreboot utilities package so it can properly +call cbfstool. + +Chances are that you already meet these requirements if you are on a Linux +environment of the listed architectures and downloaded the Libreboot utilities +package from an official source. If not, it shouldn't be too hard to use a +Linux LiveCD of your choice which provides these essentials. + +Optionally, you should make sure your EDITOR variable is set. Otherwise, +grubeditor.sh will default to using vi, which may not exist on your system. You +can override this default or the contents of your EDITOR variable using the +**-e** or **--editor** command. + +## Usage help + +grubeditor.sh takes a number of options, the only one which is required being a +valid Libreboot ROM image that uses the GRUB2 payload and contains both +_grub.cfg_ and _grubtest.cfg_ files. Additional options should come _before_ the +ROM image file on the command line. + +grubeditor.sh supports combining several short options with a single hyphen +like **-ris**, but you can also list them separately like **-r -i -s**. Long +options must always be written as standalone arguments. + +You can use the **-h** or **--help** option to view a brief summary of the +options available. Consider this guide a more extensive version of this screen. + +Lastly, you can check which version of grubeditor.sh you are using with the +**-v** or **--version** option. + +## Editing configuration files + +Invoked without any arguments except for the ROM image, grubeditor.sh will +attempt to extract the _grubtest.cfg_ file from the provided ROM image and +launch it in your editor of choice. If you make changes to the file, +grubeditor.sh will incorporate your changes into a new ROM image with the same +name in the same directory, except that the new ROM file will end with +".modified". You can then flash this ROM image to your platform's BIOS chip. + +If you would prefer to edit the actual _grub.cfg_ configuration file, use the +**-r** or the **--realcfg** option. Everything else will work the same except +that your editor will open the _grub.cfg_ instead. + +If you would prefer to overwrite your existing ROM image instead of creating a +new one ending in ".modified" use the **-i** or **--inplace** option. +Naturally, you can combine this option with the **-r/--realcfg** option +described above. + +## Swapping grub.cfg and grubtest.cfg + +grubeditor.sh supports swapping the _grub.cfg_ and _grubtest.cfg_ configuration +files with the **-s** or **--swap** option. This will create a new ROM image +alongside the existing ROM image ending with ".modified" which has these files +swapped. Naturally, you can request this operation overwrite the existing file +instead using the **-i/--inplace** option. + +Note that the script will automatically modify the "Load test configuration +(grubtest.cfg)" menu entry in both configuration files during this operation. +If this was not done, these entries would end up being self-referential after +the rename, breaking their intended functionality of changing between the +configuration files. + +For best results, please do not modify this section without studying the source +code of _grubeditor.sh_ and making sure your edits do not impact the script's +ability to perform this modification + +## Swapping grub.cfg and grubtest.cfg + +grubeditor.sh supports comparing _grub.cfg_ and _grubtest.cfg_ files for +differences with the **-d** or **--diffcfg** option. This uses the diff command +by default, but if you want to use another program (e.g. vimdiff), you can +specify it with the **-D** or **--differ** option. Note that this mode is only +intended to show differences in the files and does not support updating the +configs themselves, so any changes you make in an interactive differ will be +ignored. + +## Extracting a configuration file + +You can simply extract a configuration file using the **-x** or **--extract** +option. This option is responsive to the **-r/--realcfg** option for choosing +between grubtest.cfg and grub.cfg. + +## Pending development + +TODO: +- allow injecting configuration files to complement the extractor. +- detect potentially devastating corner cases, however rare they may actually be +- i can't specify a quoted command line with arguments to -e or -D, why? +- support editing both config files if using an interactive differ +- work with other types of files besides the grub configuration files. + +## Conclusion + +I hope that grubeditor.sh will significantly ease modifying your configuration +files in your Libreboot ROM files. + +Should you find any bugs or want any feature requests, please don't hesitate to +email me or bug me on IRC. diff --git a/i18n/fr_FR/docs/grub/index.md b/i18n/fr_FR/docs/grub/index.md new file mode 100644 index 00000000..65d4863f --- /dev/null +++ b/i18n/fr_FR/docs/grub/index.md @@ -0,0 +1,103 @@ +--- +title: GRUB payload +x-toc-enable: true +... + +This section relates to the GRUB payload used in libreboot. + +Changing the background image in GRUB +===================================== + +Use cbfstool from libreboot\_util, or +libreboot\_src/coreboot/util/cbfstool/ if you want to build from source. + + $ ./cbfstool yourrom.rom remove background.png -n background.png + $ ./cbfstool yourrom.rom add -f background.png -n background.png -t raw + +When you've done this, re-flash your ROM and you should have a new +background at boot time. + +Setting font in GRUB (for reference) +==================================== + +You don't need to do this unless you would like to change the default +font yourself.
