LUKS works on all machines, with or without cryptographic chipsets (e.g. Intel Trusted Platform Module, TPM). I believe it can make use of microprocessor cryptographic acceleration instructions (e.g. Intel Advanced Encryption Standard Instructions, AES-NI).


The Debian 5 installer can set up a system disk with an unencrypted boot/ partition and all other partitions encrypted. You enter the passphrase when the system boots.


The command-line utility 'cryptsetup' and the file /etc/crypttab can be used to make changes, add and remove drives and partitions, etc..
