This update may brick your motherboard
There's one good reason why users don't update *and* why vendors don't advertise their updates:
"WARNING! There is a small chance this update may render your motherboard unusable."
I've had boot problems when updating a BIOS that have only been resolved after flashing it again and again over several days with no obvious reason why the problems arose or why they suddenly stopped arising. There are few components whose failure can spoil my day so much. Therefore, I typically only update my BIOS when I'm doing a processor upgrade and need a newer BIOS version to handle it.
Where's the motivation to update if you might be faced with buying new hardware? What is a small chance? One in 1,000? One in a million?
