A security device for a personal computer that interrupts the normal boot sequence to execute a secure operating system. The secure operating system may be stored and executed from configurable memory means on the security device. Alternatively, the configurable memory means may store executable code for creating a RAM drive and the secure operating system may be executed in the RAM drive from an image on a storage device.
