My experience with Linux hasn't been favorable. I am working with Scientific Linux, based on RedHat Enterprise
It is true that you can boot into Windows and start DES and then let it run in Stealth mode.
When you first boot into Linux, DES will be active, and that is a good thing.
However, at some point in the shutdown process DES is disabled. This is a double problem, because at the next boot the BIOS will complain that DES has been disabled and the boot process will wait for user acknowledgement (keyboard entry). This means that when running with DES you cannot remotely reboot a Linux box -- somebody will have to walk over to the keyboard during the boot process.
This is unacceptable to me, so I have to run Linux with DES turned off.
