Yea, both methods get the info from smbios. So back to the original question about reasonable output from kenv, I would expect it to contain all the same basic information that dmidecode fetches. If it is missing something then it is a bug, otherwise that is the data the bios maker has provided and the script will need to handle it. cheers, Andrew _______________________________________________ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "freebsd-hackers-unsubscr...@freebsd.org"
