A friend who is an avid Linux user, and a prolific programmer, specializing in graphics effects, tried installing FreeBSD in what he describes as “a machine conjured from parts found in my closet” :-)

- Stop the boot process at the boot-loader prompt, “OK”.
- At the loader prompt, type:
- Boot in “verbose” mode:
Then, you can save the “/var/run/dmesg.boot” file, and if anything seems odd or out of the ordinary, you will have enough debugging info to post to FreeBSD developers, to troubleshoot any remaining issues further :-)
