When I run aflash2 it tells me, "Your current BIOS is too old to be supported." I tried flashing with Asus EZ Flash through the BIOS too, still SLIC 2.0.
Still SLIC 2.0, I'm on the 0803 BIOS now. I suppose I should mention I'm flashing a P5E Deluxe with the Rampage BIOS, they're the same motherboard though, so I don't think it makes a difference.
