Before being merged with the commitdc6e1f32c1("Import website-build to build the GNU Boot website."), website-build was a separate git repository. And so, even after the merge, until the commit20d122e94a("website-build: use website from local git repository."), it still worked in the same way and still downloaded the website from git. This prevented merging the website and website-build directories together as the GNU Boot repository also needed to be a valid Untitled website repository as well. Now after this commit, the website is built from the same git tree, so we can simply adjust the build scripts to be able to move things around. In addition of making things more clear for contributors, it also simplify the migration to haunt as with haunt we typically have the haunt.cfg (and the autotools build code if needed) code in the top directory and the markdown files in a subdirectory.

title: How to install NetBSD on x86 GNU GRUB payload
|
|
x-unreviewed: true
|
|
...
|
|
|
|
GRUB supports booting NetBSD kernels directly. However, you're better off
|
|
simply using the SeaBIOS payload; BSD works well with BIOS or UEFI setups.
|
|
|
|
GRUB is acceptable for booting unencrypted BSD installations. However,
|
|
encrypted BSD installations will probably require the use of SeaBIOS/Tianocore.
|
|
|
|
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.
|
|
|
|
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. You can also use the same
|
|
instructions with a NetBSD ISO image.
|
|
|
|
Prepare the USB drive (in OpenBSD or NetBSD)
|
|
-----------------------------------------------
|
|
|
|
If you downloaded your ISO on a OpenBSD or NetBSD system, here is how
|
|
to create the bootable NetBSD 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
|
|
NetBSD installer to it with dd. For example:
|
|
|
|
doas netbsd.iso 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 NetBSD 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=install60.fs of=/dev/sdX bs=8M; sync
|
|
dd if=netbsd.iso 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 NetBSD without full disk encryption
|
|
----------------------------------------------
|
|
|
|
You might have to use an external USB keyboard during the installation.
|
|
Press C to access the GRUB terminal.
|
|
|
|
grub> knetbsd -r sd0a (usb0,netbsd1)/netbsd
|
|
grub> boot
|
|
|
|
It will start booting into the NetBSD installer. Follow the normal
|
|
process for installing NetBSD.

|
|
Booting
|
|
-------
|
|
|
|
Press C in GRUB to access the command line:
|
|
|
|
grub> knetbsd -r wd0a (ahci0,netbsd1)/netbsd
|
|
grub> boot
|
|
|
|
NetBSD will start booting. Yay!
|
|
|
|
Configuring Grub
|
|
----------------
|
|
|
|
If you don't want to drop to the GRUB command line and type in a
|
|
command to boot NetBSD every time, you can create a GRUB configuration
|
|
that's aware of your NetBSD installation and that will automatically be
|
|
used by libreboot.
|
|
|
|
On your NetBSD root partition, create the `/grub` directory and add
|
|
the file `libreboot_grub.cfg` to it. Inside the
|
|
`libreboot_grub.cfg` add these lines:
|
|
|
|
default=0
|
|
timeout=3
|
|
|
|
menuentry "NetBSD" {
|
|
knetbsd -r wd0a (ahci0,netbsd1)/netbsd
|
|
}
|
|
|
|
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 NetBSD on the list. After 3
|
|
seconds NetBSD will boot, or you can hit enter to boot.
|
|
|
|
Troubleshooting
|
|
===============
|
|
|
|
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 NetBSD
|
|
it can be problematic when they are trying to switch to a framebuffer
|
|
because it doesn't exist.
|
|
|
|
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.
