title: How to install FreeBSD on x86 GNU GRUB payload
|
|
...
|
|
|
|
This guide was written for FreeBSD at a time where Libreboot was still
|
|
fully free.
|
|
|
|
FreeBSD is not a fully free softrware operating system / distribution
|
|
and so the GNU Boot project can't force its contributors to test GNU
|
|
Boot with FreeBSD.
|
|
|
|
Because of that this page is only meant for people already Using
|
|
FreeBSD. See the [BSD index page](index.md) for more details about how
|
|
GNU Boot deals with this issue and the way forward to a better support
|
|
for BSD systems in GNU Boot.
|
|
|
|
According to the Libreboot project at the time, FreeBSD might show
|
|
graphical corruption during bootup. They also advised that you could
|
|
fix this by altering the order in which kernel modules/drivers were
|
|
loaded. First, by trying to move video to an earlier stage on the boot
|
|
process, or by trying to move it to a later stage instead. They
|
|
advised that with this, you should have been able to get a working
|
|
display.
|
|
|
|
They also told that freebsd.img was the installation image for
|
|
FreeBSD. And that you might have to adapt the filename accordingly,
|
|
for whatever FreeBSD version you used.

Prepare the USB drive (in FreeBSD)
|
|
----------------------------------
|
|
|
|
[This page](https://www.freebsd.org/doc/handbook/bsdinstall-pre.html) on
|
|
the FreeBSD website shows how to create a bootable USB drive for
|
|
installing FreeBSD. Use the *dd* on that page.
|
|
|
|
Prepare the USB drive (in NetBSD)
|
|
---------------------------------
|
|
|
|
[This
|
|
page](https://wiki.netbsd.org/tutorials/how_to_install_netbsd_from_an_usb_memory_stick/)
|
|
on the NetBSD website shows how to create a NetBSD bootable USB drive
|
|
from within NetBSD itself. You should use the *dd* method documented
|
|
there; you can use this with any ISO, including FreeBSD.
|
|
|
|
Prepare the USB drive (in LibertyBSD or OpenBSD)
|
|
------------------------------------------------
|
|
|
|
If you downloaded your ISO on a LibertyBSD or OpenBSD system, here is
|
|
how to create the bootable FreeBSD USB drive:
|
|
|
|
Connect the USB drive. Check dmesg:
|
|
|
|
dmesg | tail
|
|
|
|
Check to confirm which drive it is, for example, if you think its sd3:
|
|
|
|
disklabel sd3
|
|
|
|
Check that it wasn't automatically mounted. If it was, unmount it. For
|
|
example:
|
|
|
|
doas umount /dev/sd3i
|
|
|
|
dmesg told you what device it is. Overwrite the drive, writing the
|
|
FreeBSD installer to it with dd. For example:
|
|
|
|
doas dd if=freebsd.img of=/dev/rsdXc bs=1M; sync
|
|
|
|
You should now be able to boot the installer from your USB drive.
|
|
Continue reading, for information about how to do that.
|
|
|
|
Prepare the USB drive (in GNU+Linux)
|
|
------------------------------------
|
|
|
|
If you downloaded your ISO on a GNU+Linux system, here is how to create
|
|
the bootable FreeBSD USB drive:
|
|
|
|
Connect the USB drive. Check dmesg:
|
|
|
|
dmesg
|
|
|
|
Check lsblk to confirm which drive it is:
|
|
|
|
lsblk
|
|
|
|
Check that it wasn't automatically mounted. If it was, unmount it. For
|
|
example:
|
|
|
|
sudo umount /dev/sdX\*
|
|
umount /dev/sdX\*
|
|
|
|
dmesg told you what device it is. Overwrite the drive, writing your
|
|
distro ISO to it with dd. For example:
|
|
|
|
sudo dd if=freebsd.img of=/dev/sdX bs=8M; sync
|
|
dd if=freebsd.img of=/dev/sdX bs=8M; sync
|
|
|
|
You should now be able to boot the installer from your USB drive.
|
|
Continue reading, for information about how to do that.

|
Installing FreeBSD without full disk encryption
|
|
-----------------------------------------------
|
|
|
|
Press C in GRUB to access the command line:
|
|
|
|
grub> kfreebsd (usb0,gpt3)/boot/kernel/kernel
|
|
grub> set FreeBSD.vfs.mountfrom=ufs:/dev/da1p3\
|
|
grub> boot
|
|
|
|
It will start booting into the FreeBSD installer. Follow the normal
|
|
process for installing FreeBSD.

Troubleshooting
|
|
===============
|
|
|
|
According to the Libreboot project at a time when it was still fully
|
|
free, most of the issues occur when using coreboot's 'text mode'
|
|
instead of the coreboot framebuffer. This mode is useful for booting
|
|
payloads like memtest86+ which expect text-mode, but for FreeBSD,
|
|
accodring to Libreboot at the time, it can be problematic when they
|
|
are trying to switch to a framebuffer because it doesn't exist.
|
|
|
|
In most cases, you should use the corebootfb ROM images. There ROM images
|
|
have `corebootfb` in the file name, and they start in a high resolution frame
|
|
buffer, provided by coreboot's `libgfxinit` library.
|
|
|
|
won't boot...something about file not found
|
|
---------------------------------------------
|
|
|
|
Your device names (i.e. usb0, usb1, sd0, sd1, wd0, ahci0, hd0, etc) and
|
|
numbers may differ. Use TAB completion.
