Launched in 2004, dmesgd aims to provide a user-submitted repository of searchable *BSD dmesgs. The dmesg(8) command displays the system message buffer's content, and during boot a copy is saved to /var/run/dmesg.boot. This buffer contains the operating system release, name and version, a list of devices identified, plus a whole host of other useful information. We hope others find this resource useful and further contribute to its growth. Contact us at [ admin at lists dot nycbug dot org ].

bo [ -abdfrnsux ] [ -o <switch> ] [ <devspec> [ <file> [ <args> ... ]]]

Boot the operating system from device given as <devspec>. If <devspec> is
omitted, value of ROM variable "bootdev" is used as a name of boot device.
And if ROM variable is not set, "scsi(0,0)" is used.

Optional argument <args> will be passed to the operating system through
bootstrapping program.

To boot from "bfs" file system constructed on <bootdev>, use -b flag and
specify name of file to be loaded as <file>. And to boot from "ufs" file
system constructed on <bootdev>, use -u flag and specify name of file to be
loaded as <file>. In these cases, bo with -f flag loads <file> as COFF or ELF
object file, otherwise bo loads <file> as absolute binary starting from

bo -x flag does not execute loaded file, returns you to ROM monitor
immediately after loading

-a flag asks you name of the operating system kernel file. -s flag boot the
operating system up with single user mode. -o flag sets the boot switch to
<switch>. Meaning of <switch> is described in the operating system's manual.
