> I remembered that most of the physical access hacks would not be possible if the disk is encrypted..

Only if you have not booted into your system through using a keyfile or a passphrase to decrypt the data, i.e. if your PC is shut down. I have full disk encryption, and when I boot into my system, it uses the keyfile with which it would perform the decryption, and boom, I have my PC ready to be accessed physically.

Would flashing BIOS post-boot really work though?

Also don't see how the article's exploit would be useful pre-decryption.
