You can get the serial number of scsi disks with "camcontrol inq da0
-S", once for each drive.  I don't have any cpus with serial numbers,
but if you have a P4 with it enabled, I think the cpuid command in
ports can print it.  As for the motherboard serial number, you'll
probably need to open the case to get that, but try the "dmidecode"
port.  My Asus board prints a serial number of "xxxxxxxxxxx", but other
boards might actually put a real value in there.
