Same here. So much less that can go wrong imo. I mean, I have experienced extremely sudden shut downs during gaming because windows update decided to reboot the pc all of the sudden. Not cool while flashing to say the least. If you have no alternative way of displaying if the bios flash goes wrong (dual bios like at least some ati cards have, alternatively pci video card available) then there is some risk involved.
In other words, do it with USB for now. The linked tutorial is very precise and easy to follow.Edited by Chris Ihao - 1/4/11 at 8:42pm
