I've had no bother with it on Asus boards up until my current one, a striker II extreme.

I don't know if it differs between manufacturers but I've been using Gigabytes @BIOS for years without a single problem, it downloads from the Internet and does a checksum and won't let you flash if it is the incorrect one for the motherboard. There are also some pretty good failsafes on the board to if you do hose it.
& you're right, I have never had a problem with flashing BIOS in Windows on a P5W, but the P5Ks, well all P35's and above have serious problems, I'm telling you through first hand experience.
