18. Is it ok to remove the battery for long periods of time?

   No, the battery powers the RTC (Real Time Clock). You shouldn't remove
   the battery except when replacing it or upgrading the memory chips.

Go to the open-boot prompt and set things up again. You lost some
important settings. At least the host id and boot step has been cleared
as you found out.
