I recently flashed the BIOS on my P5N32-E SLI from 1404 to 1601, and when it was done, the board would no longer successfully POST with both of my 8800GTS 512s plugged in. Every time it POSTed it would fail either upon listing the CPU speed, or while searching for HDDs and optical drives. Problem disappeared when I removed my second 8800GTS. I wondered if maybe my power supply (460 watt Enermax, 33A +12V) was starting to fail, because it is a little low on juice to power an SLI system. But it powered it just fine for about 4 months. So that led me to believe that this BIOS flash has somehow caused the board to not want to POST anymore when both cards are plugged in. So I'm wondering if it's possible to flash my BIOS back to an older version, one that actually allows SLI to work. EDIT: Fixed, see post 10.
