I just went through this...not 15-20 minutes ago from this response...ahh, the joys of messing around with new expensive hardware
Anyway, it does not sound like you need to do anything with CMOS...CMOS and BIOS are separate things.
You are focusing on BIOS, which in this case should involve the jumpers. By default they are on the 1/2 position. You do not need to remove the jumper as you are not wanting to recover a bad bios...because it does not look like any BIOS attempt failed. You are wanting to "reconfigure bios" so you should place the jumper to the 2/3 position.
Now I'm saying this assuming you didn't do anything majorly funky after your initial post and assuming your situation is like mine.
