Your BIOS should be a set and forget item. I don't even think I've been in any of my BIOS's for 1-2 yrs.
What are your options:
-Flash to a different build
-Live with it
Another revision may or may not act the same. A word of caution though. If your system is working as it should, there is not reason to flash. You shouldn't need to spend any time in the BIOS beyond initial set up or configuration.
