boot.conf

It's possible to set default boot parameters so you don't need to re-enter them each time the server boots up.

To give yourself more time to choose a different kernel at bootup time:

# echo "set timeout 30" >> /etc/boot.conf

To set the default boot image:

# echo "set image /bsd.mp" >> /etc/boot.conf

To set a specific disk to boot from:

boot> set device hd2a
boot> ls
stat(hd2a:/.): Invalid argument
(not valid disk)
boot> set device hd1a
boot> ls
... files ...

boot> boot -s hd1a:/bsd
