## Install an OpenBSD image
### Getting the OpenBSD image
The list of the mirrors is here: https://www.openbsd.org/ftp.html
Get the last version, here 6.5
~~~
wget ftp://ftp.irisa.fr/pub/mirrors/OpenBSD/6.5/amd64/install65.fs
~~~
### Write the image to an USB Key
My usb key is on /dev/sde
~~~
dd if=install65.fs of=/dev/sde bs=1M
~~~
### Boot USB & install
Select the tty output in 115200 on com0

Welcome to the OpenBSD/amd64 6.5 installation program.
(I)nstall, (U)pgrade, (A)utoinstall or (S)hell? I
Terminal type? [vt220]
System hostname? (short form, e.g. 'foo') cerbere
Password for root account? (will not echo)
Password for root account? (again)
Start sshd(8) by default? [yes]
Change the default console to com0? [yes]
Available speeds are: 9600 19200 38400 57600 115200.
Which speed should com0 use? (or 'done') [115200]
Setup a user? (enter a lower-case loginname, or 'no') [no]
Since no user was setup, root logins via sshd(8) might be useful.
WARNING: root is targeted by password guessing attacks, pubkeys are safer.
Allow root ssh login? (yes, no, prohibit-password) [no] yes
Available disks are: sd0 sd1.
Which disk is the root disk? ('?' for details) [sd0]
No valid MBR or GPT.
Use (W)hole disk MBR, whole disk (G)PT or (E)dit? [whole]
