You should see how the system booted, i.e.,  EFI
 by using dmesg:
   dmesg | grep -i efi
If this is empty, then this was a BIOS boot (assuming you are not
booting on some virtual machine.)


You can also check the logs created by syslogd under: /var/svc/log
Do something like grep -i whatever /var/svc/log/*log

Also check /var/adm/messages. Scroll down to the current date/boot time
and read though how your system was initiated.
