Not to say what happened to me will happen to others, but I had BIOS version 2004 (Yes, one that showed up, and a day later was taken down, which worried me quite a bit when I saw that), that update went fine. Couple of weeks ago, saw 2101 come up. Now of course, Asus, as usual, keeps it simple "Stability improvements" and nobody you call can explain further, it's great. Having issues with remotely waking my PC which used to work fine with no settings changes, I figured to update the Bios. Well, my PC comes back from Asus this weekend, since the BIOS update bricked the PC. Mid-way through in Windows, the progress bar stops and that was that.

Just a heads up for those in the same version upgrade situation.
