Documentation: *major* cleanup.
Cleanup was long overdue. Old structure was messy and inefficient.

+ <h1 id="grub_font">Setting font in GRUB (for reference)</h1>
+
+ <p>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)</p>
+
+ <p>The old font used was Unifont, and this had some missing characters: for instance, the border showed ??? characters instead of lines.</p>
+
+ <p>I tried DeJavu Sans Mono from this website:
+ <a href="http://dejavu-fonts.org/wiki/Download">dejavu-fonts.org</a></p>
+
+ <p>Specifically, the version that I chose was the latest at the time of writing (Saturday 21 June 2014):
+ <a href="http://sourceforge.net/projects/dejavu/files/dejavu/2.34/dejavu-fonts-ttf-2.34.tar.bz2">this one</a></p>
+
+ <p>This is a free font that is also contained in GNU/Linux distributions like Trisquel or Parabola.</p>
+
+ <p><b>$ cd libreboot_src/grub</b><br/>
+ compile grub ('build' script has the info on how to do this)<br/>
+ come back out into libreboot_src/resources/grub:<br/>
+ <b>$ cd ../libreboot_src/resources/grub/font</b></p>
+
+ <p>I took Dejavu Sans Mono from dejavu (included in this version of libreboot) and did:<br/>
+ <b>$ ../../../grub/grub-mkfont -o dejavusansmono.pf2 ../../../dejavu-fonts-ttf-2.34/ttf/DejaVuSansMono.ttf</b></p>
+
+ <p>I then added the instructions to 'build' script to include resources/grub/dejavusansmono.pf2 in all of the ROM's in root of cbfs.<br/>
+ I then added that instructions to the grub.cfg files (to load the font):<br/>
+ <b>loadfont (cbfsdisk)/dejavusansmono.pf2</b></p>

+
+ <p>
+ Keymaps are stored in resources/utilities/grub-assemble/keymap/.
+ </p>
+
+ <p>
+ Example (French Azerty):<br/>
+ <b>$ ckbcomp fr &gt; frazerty</b><br/><br/>
+ Go in grub directory:<br/>
+ <b>cat frazerty | ./grub/grub-mklayout -o frazerty.gkb</b>
+ </p>
+
+ <p>
+ You must make sure that the files are named keymap and keymap.gkb (where 'keymap' can be whatever you want).
+ </p>
+
+ <p>
+ Then from the above example, you would put <b>frazerty</b> in <b>resources/utilities/grub-assemble/keymap/original/</b> and
+ the <b>frazerty.gkb</b> file goes under <b>resources/utilities/grub-assemble/keymap/</b>
+ </p>
+
+ <p>
+ The scripts <b>build</b> and <b>buildrom-withgrub</b> will automatically see this, and automatically build
+ ROM's with your custom layout (given the name) and include them under bin. Example: <b>libreboot_frazerty.rom</b>.

+
+ <h2 id="grub_ukdvorak_keyboard">UK Dvorak keyboard layout in GRUB (for reference)</h2>
+
+ <p>
+ 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
+ </p>
+
+ <p><b>$ cat ukdvorak | ./grub/grub-mklayout -o ukdvorak.gkb</b></p>
