Just buy the same one that's already in your mainboard, that's the
easiest option. The chips should be available from most electronics stores.
An example in Germany: http://www.bios-chip.de/bios-chips,_leer.htm

Some chips supported by 'flashrom' are listed here:

It's not as bad as I probably made it sound :) The risk to damage your
board is very very small, AFAIK. The worst that can usually happen is
that you overwrite your BIOS chip with a bogus image and cannot boot
anymore. Or put it in the socket the wrong way(which I did once), in
which case it'll get pretty hot and will probably be damaged (usually
only the chip though, but not your board).

The solution is to pull a backup image first, and flash it to an empty
chip, test booting with that chip, and if it works put it in your bank
safe :) From there you can mess up if you want, as you can always use
that working backup BIOS chip if things go wrong.

The http://www.bios-chip.de/ website (for example) also offers BIOS
chips which are already flashed with your factory (AMI/AWARD/Phoenix)
BIOS for ca. 10 Euros, that's another easy way to get a backup...
