ABSTRACT:
A data processing system and method of password protecting the boot of a data processing system are disclosed. According to the method, in response to an attempt to boot the data processing system utilizing a boot device, the boot device is interrogated for a password. If the boot device supplies password information corresponding to that of a trusted boot device, the data processing system boots utilizing the boot device. If, however, the boot device does not supply password information corresponding to that of a trusted boot device, booting from the boot device is inhibited. In a preferred embodiment, the password information comprises a unique combination of the boot device's manufacturer-supplied model and serial numbers.
