we are trying to do a rather off-the-wall thing. the big picture: we have classified data that we want to encrypt on all writable partitions on our hard drive(s). we need to store the encryption/decryption "keys" - two redundant 32 byte entries - for this data external to these drives. one place we thought of was in bios. these keys will be used for every read/write from/to the hard drives, so we would like them be be accessible in the lower part of ram like all other bios data is after bootup (if possible). the keys may need to be changed sometimes at boot-up by a third party application and NOT by entering the standard bios menus, which may be the trickiest part. is any of this at all possible? thanks! t.
