# OpenBSD FDE Setup This is a condensed version of [OpenBSD FDE FAQ](https://www.openbsd.org/faq/faq14.html#softraid). Boot installer, drop to shell with "s"
# cd /dev && sh MAKEDEV sd0
# dd if=/dev/urandom of=/dev/rsd0c bs=1m
# fdisk -iy -g -b 960 sd0 # GPT / without -g and -b for MBR
# disklabel -E sd0
Note, switch to kbd en before setting the password as this is what you have on the boot prompt.
# bioctl -c C -l sd0a softraid0
# dd if=/dev/zero of=/dev/rsd1c bs=1m count=1
Ctrl+D to restart the installer. Choose sd1 as install target. If sd1 is not present:
# cd /dev && sh MAKEDEV sd1
When the installer later asks about installing with MBR or GPT layout, choose MBR. Even if you boot via UEFI/GPT.
