I thought it may be a good idea for future reference to use my favourable Google status to tell the world about my experiences flashing the BIOS on my Asus A8V Deluxe motherboard.
Note: this post is a bit long and windy, but there's an hilarious tech support reply in the end...
A couple of weeks back I bought a new computer. Nice and fast, nice and cheap. In an effort to make the computer as up to date as possible, I decided to upgrade the BIOS. Using Asus (ugly-as-sin) Windows based flash utility, I upgraded to the latest non-beta BIOS. Unfortunately that resulted in a problem with my CPU fan, so I wanted to use the same utility to get me back to my original BIOS version. Turns out that it can't downgrade your bios. So instead I decided to try to see if the fan-problem was fixed in the available beta BIOS. Not only didn't that bios fix the problem, it also made my floppy drive inaccessible. 'A floppy drive?' you would say, 'what do you need that for?'. Well, for flashing your bios outside of windows...
