<h1>How to install LibertyBSD or OpenBSD on a libreboot system</h1>
<p>
NOTE: This guide was written for OpenBSD by the person who contributed
it, but the libreboot project recommends LibertyBSD.
LibertyBSD is a version of OpenBSD without proprietary software
in the repositories (OpenBSD distributes firmware blobs for
devices inside its kernel).
Go to the <a href="http://libertybsd.net/">LibertyBSD website</a>
-- TODO: test on LibertyBSD and prioritise that in this guide.
</p>
<p>
This section relates to preparing, booting and installing
OpenBSD on your libreboot system, using nothing more than a USB flash drive (and <i>dd</i>). They've only been tested on a Lenovo ThinkPad x200.

<p>
<b>This section is only for the GRUB payload. For depthcharge (used on CrOS devices in libreboot), instructions
have yet to be written in the libreboot documentation.</b>
</p>
</div>
<div id="prepare" class="section">
<p>
install60.fs is the installation image for OpenBSD 6.0. Adapt
the filename accordingly, for a different OpenBSD version or
LibertyBSD.
</p>
<h2>Prepare the USB drive (in LibertyBSD or OpenBSD)</h2>
<p>
If you downloaded your ISO on a LibertyBSD or OpenBSD system,
here is how to create the bootable LibertyBSD/OpenBSD USB drive:
</p>
<p>
Connect the USB drive. Check dmesg:<br/>
<b>$ dmesg | tail</b><br/>
Check to confirm which drive it is, for example, if you think its sd3:<br/>
<b>$ disklabel sd3</b>
</p>
<p>
Check that it wasn't automatically mounted. If it was, unmount it. For example:<br/>
<b>$ doas umount /dev/sd3i</b><br/>
</p>
<p>
dmesg told you what device it is. Overwrite the drive, writing the OpenBSD installer to it with dd. For example:<br/>
<b>$ doas dd if=install60.fs of=/dev/rsdXc bs=1M; sync</b><br/>
</p>
<p>
You should now be able to boot the installer from your USB drive. Continue reading, for
information about how to do that.
</p>
<p>

</p>
<h2>Prepare the USB drive (in NetBSD)</h2>
<p>
<a href="https://wiki.netbsd.org/tutorials/how_to_install_netbsd_from_an_usb_memory_stick/">This page</a>
on the NetBSD website shows how to create a NetBSD bootable USB drive
from within NetBSD itself. You should use the <em>dd</em> method
documented there. This will also work with the OpenBSD image.
</p>
<h2>Prepare the USB drive (in FreeBSD)</h2>
<p>
<a href="https://www.freebsd.org/doc/handbook/bsdinstall-pre.html">This page</a>
on the FreeBSD website shows how to create a bootable USB drive
for installing FreeBSD. Use the <em>dd</em> on that page. You can
also use the same instructions with a OpenBSD ISO image.
</p>
<h2>Prepare the USB drive (in GNU/Linux)</h2>
<p>
If you downloaded your ISO on a GNU/Linux system,
here is how to create the bootable OpenBSD USB drive:
</p>
<p>
Connect the USB drive. Check dmesg:<br/>
<b>$ dmesg</b><br/>
Check lsblk to confirm which drive it is:<br/>
<b>$ lsblk</b>
</p>
<p>
Check that it wasn't automatically mounted. If it was, unmount it. For example:<br/>
<b>$ sudo umount /dev/sdX*</b><br/>
<b># umount /dev/sdX*</b>
</p>
<p>
dmesg told you what device it is. Overwrite the drive, writing your distro ISO to it with dd. For example:<br/>
<b>$ sudo dd if=install60.fs of=/dev/sdX bs=8M; sync</b><br/>
<b># dd if=install60.fs of=/dev/sdX bs=8M; sync</b>
</p>
<p>
You should now be able to boot the installer from your USB drive. Continue reading, for
information about how to do that.

</div>
<div id="noencryption" class="section">
<h2>Installing OpenBSD without full disk encryption</h2>
<p>
Press C in GRUB to access the command line:
</p>
<p>
grub> <b>kopenbsd (usb0,openbsd1)/6.0/amd64/bsd.rd</b><br/>
grub> <b>boot</b>
</p>
<p>
It will start booting into the OpenBSD installer. Follow the normal process for installing OpenBSD.
</p>
<p>
<a href="#pagetop">Back to top of page</a>.
</p>
</div>
<div id="encryption" class="section">
<h2>Installing OpenBSD with full disk encryption</h2>
<p>
Not working. You can modify the above procedure (installation w/o encryption) to install OpenBSD using full disk encryption, and it appears to work, except that its not yet clear how to actually <i>boot</i> an OpenBSD+FDE installation using libreboot+Grub2. If you get it working, please let us know.

<p>
<a href="#pagetop">Back to top of page</a>.
</p>
</div>
<div id="booting" class="section">
<h2 id="booting">Booting</h2>
<p>
Press C in GRUB to access the command line:
</p>
<p>
grub> <b>kopenbsd -r sd0a (ahci0,openbsd1)/bsd</b>
</p>
<p>
OpenBSD will start booting. Yay!
</p>
<p>
<a href="#pagetop">Back to top of page</a>.
</p>
</div>
<div id="configuring_grub" class="section">
<h2>Configuring Grub</h2>
<p>
If you don't want to drop to the GRUB command line and type in a command to boot OpenBSD every time, you can create a GRUB configuration that's aware of your OpenBSD installation and that will automatically be used by libreboot.
</p>
<p>
On your OpenBSD root partition, create the <b>/grub</b> directory and add the file <b>libreboot_grub.cfg</b> to it. Inside the <b>libreboot_grub.cfg</b> add these lines:
<p><b>
default=0
timeout=3
menuentry "OpenBSD" {<br>
kopenbsd -r sd0a (ahci0,openbsd1)/bsd<br>
}<br>
</b></p>
<p>The next time you boot, you'll see the old Grub menu for a few seconds, then you'll see the a new menu with only OpenBSD on the list. After 3 seconds OpenBSD will boot, or you can hit enter to boot.
<p>

</p>
</div>
<div id="troubleshooting" class="section">
<h1>Troubleshooting</h1>
<p>
Most of these issues occur when using libreboot with coreboot's 'text mode' instead of the coreboot framebuffer.
This mode is useful for booting payloads like memtest86+ which expect text-mode, but for OpenBSD
it can be problematic when they are trying to switch to a framebuffer because it doesn't exist.
</p>
<p>
In most cases, you should use the vesafb ROM images. Example filename: libreboot_ukdvorak_vesafb.rom.
</p>
<h2>won't boot...something about file not found</h2>
<p>
Your device names (i.e. usb0, usb1, sd0, sd1, wd0, ahci0, hd0, etc) and numbers may differ. Use TAB completion.
