Hi all, Tossed this question up on twitter, but it might get additional audience here... How does one ascertain a host's serial number with FreeBSD sans hint.smbios.0.mem (stable/10 or 11, for example) on a system in pure UEFI mode? hint.smbios.0.mem [ in -CURRENT ] stores the address of the smbios table. dmidecode uses this as it's entry point to the smbios table where the host's serial number can be found. Variants of `dd if=/dev/mem ... | strings | grep ''` worked, but also rebooted the hardware on occasion. Not ideal. -- Take care Rick Miller
