GRUB payload

- This section relates to the GRUB payload used in libreboot. -

- Or Back to main index. -

Changing the background image in GRUB
Setting font in GRUB
GRUB keyboard layouts -
- Custom keyboard layout in GRUB
- UK Dvorak keyboard layout in GRUB
-

- -

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. - (this is just for reference. It has already been done for you)

- -

The old font used was Unifont, and this had some missing characters: for instance, the border showed ??? characters instead of lines.

- -

I tried DeJavu Sans Mono from this website: - dejavu-fonts.org

- -

Specifically, the version that I chose was the latest at the time of writing (Saturday 21 June 2014): - this one

- -

This is a free font that is also contained in GNU+Linux distributions like Debian, Devuan or Parabola.

- -

$ cd libreboot_src/grub
- compile grub (the build scripts info on how to do this)
- come back out into libreboot_src/resources/grub:
- $ cd ../libreboot_src/resources/grub/font

- -

I took Dejavu Sans Mono from dejavu (included in this version of libreboot) and did:
- $ ../../../grub/grub-mkfont -o dejavusansmono.pf2 dejavu-fonts-ttf-2.34/ttf/DejaVuSansMono.ttf

- -

I then added the instructions to 'gen.sh' script in grub-assemble to include resources/grub/dejavusansmono.pf2 - in all of the ROM images, at the root of the GRUB memdisk.
- I then added that instructions to the grub.cfg files (to load the font):
- loadfont (memdisk)/dejavusansmono.pf2

- -

GRUB keyboard layouts (for reference)

- -

Custom keyboard layout in GRUB (for reference)

- -

- Keymaps are stored in resources/utilities/grub-assemble/keymap/. -

- -

- Example (French Azerty):
- $ ckbcomp fr > frazerty

- Go in grub directory:
- cat frazerty | ./grub/grub-mklayout -o frazerty.gkb -

- -

- You must make sure that the files are named keymap and keymap.gkb (where 'keymap' can be whatever you want). -

- -

- Then from the above example, you would put frazerty in resources/utilities/grub-assemble/keymap/original/ and - the frazerty.gkb file goes under resources/utilities/grub-assemble/keymap/ -

- -

- The build scripts will automatically see this, and automatically build - ROM images with your custom layout (given the name) and include them under bin. Example: libreboot_frazerty.rom. -

- -

UK Dvorak keyboard layout in GRUB (for reference)

- -

- ukdvorak had to be created manually, based on usdvorak. diff them (under resources/utilities/grub-assemble/keymap/original) - to see how ukdvorak file was created -

- -

$ cat ukdvorak | ./grub/grub-mklayout -o ukdvorak.gkb
