For instance, one of the lines reads: > sa0 at adv0 bus 0 target 4 lun 0 many (most?) of the items in dmesg are device drivers and have manpages. so first read man man then try things like man -aw sa you'll see: /usr/share/man/cat8/sa.8.gz (source: /usr/share/man/man8/sa.8.gz) /usr/share/man/man4/sa.4.gz which tells you there are two man pages for sa. one is what you are looking for, one is not, so use man 4 sa to see the right one. repeat that for all the things in dmesg and you'll learn a lot of what you're looking for. This can potentially throw you off by some things that have the same name and are not device drivers. eg man 4 fd wil not get you the floppy driver, but man 4 fdc will. hth, Tim To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
