Security system for a stand-alone computer |
摘要 |
A security system for stand alone and portable computer hosts which utilizes both a hardware key and a password key to enable-access to the computer host. The entry of the password key and the hardware key is monitored by the keyboard controller. The keyboard controller alters a status bit during the POST portion of the host code if access is granted. The host security is divided into two levels of security, a first administrative level and a second user level. The administrative level is accessible by the entry of a first password or by the hardware key and enables access to all levels of the host SET-UP configuration. The user level is accessible by the entry of a second password and only enables access to a limited portion of the setup configuration.
