I do indeed have a Raid BIOS v. 4.84, although I'm using the 704-2 Beta Bios instead of the official BIOS 623-3    I've found the beta bios to be more stable for me.  But don't get me started on how I had to loosen my RAM timings just to get stability when I wasn't even overclocking.  I used to get blue screens a lot, STOP errors or IRQL errors until I adjusted my RAM timings.  I left memtest run for hours and I would only get errors in tests 5 and 8 and I read somewhere that those were do to timings.  But thats all behind me now.    Now that my system is stable I decided I would try for the next experiment: RAID.  The SATAII RAID hardrive  setup has been giving me headaches too, but I look at these things as a challenge. I reinstalled windows over the weekend with my slipstreamed nLite CD following Fernando's instructions to the letter and it worked like a charm.  Thanks, Fernando!  If only that were the end of things, but its not without new problems too, I now have that annoying "safely remove hardware"  icon in the task bar, and I have some unknown devices in device manager that I'm pretty sure weren't there when I used the RAID drivers from the set included posted on DFI's nF4 page.  The one I'm most concerned about is a PCI Bridge device, which I assume is related to SLI.  But I only have one graphics card right now.  Incidently those drivers that I used previsously are the same ones that Reinvented is talking about.  They aren't new, the drivers have dates from 2004, but the .zip file was posted on 2006/1/23.  I'm going to try to fix the issues above tonight and I'll post here with my results.
