Yeah, it can get even worse: in my case, the BIOS update was supposed to fix a problem - which it didn't. Instead, it broke suspend-to-ram and I couldn't replay the old BIOS because the stupid version check said that you cannot update to an older version. Dumb idiots - David is as every bit as right when saying that BIOS programmers smoke crack!
And it can get even more worse: you don't get a BIOS update because the "product has reached end of life... " and all you dumb board buyers should shove it.
Yours is yet another of the gazillion BIOS nightmares people post all over the net. Maybe we should put all those stories along with dmidecode info et al for proper identification on wiki.kernel.org, for people who want to buy a board. The problem with a b0rked BIOS is that you don't always notice it right after you buy the board but after some time of using it and maybe then it is too late to return it.
