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 Trisquel 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
