title: How to install NetBSD on x86 GNU GRUB payload
|
|
x-toc-enable: 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.
