Method and apparatus for selectively locking a system password of a computer system

A machine-executed method for securing a personal computer system, said computer system undergoing an initiation process whenever said computer system is powered on from a powered off state or re-initiated from a powered on state, comprising:

• (a) storing within said computer system a system password for controlling access to said computer system, said system password capable of being selectively enabled and disabled by a user;
• (b) storing within said computer system a setup password for controlling access to administrator functions of said computer system, said setup password capable of being selectively enabled and disabled by a system administrator;
• (c) storing within said computer system a system password status associated with said system password, said system password status being in either a "locked" or "unlocked" state;
• (d) during said initiation process, receiving a request from said user of said personal computer system to disable said system password;
• (e) if said system password status is in the "locked" state, then ignoring said request of said user to disable said system password;
• (f) if said system password status is in the "unlocked" state, then disabling said system password;
• and
• (g) completing said initiation process.

A machine-executed method for securing a personal computer system, said computer system having an executable setup utility program that is executed upon request of a user, comprising:

• (a) storing within said computer system a system password for controlling access to said computer system, said system password capable of being selectively enabled and disabled by a user;
• (b) storing within said computer system a setup password for controlling access to administrator functions of said computer system, said setup password capable of being selectively enabled and disabled by a system administrator;
• (c) storing within said computer system a system password status associated with said system password, said system password status being in either a "locked" or "unlocked" state;
• (d) during said execution of said setup program utility, receiving a request from said user of said personal computer system to change said system password;
• (e) if said setup password is disabled, then permitting said user to change said system password;
• (f) if said setup password is enabled, then performing the following steps:
• (1) if said user correctly entered said setup password, then permitting said user to change said system password;
• and
• (2) if said user incorrectly entered said setup password, then prohibiting said user from changing said system password;
• and
• (g) continuing with execution of said setup program utility.

A machine-executed method for selectively permitting a personal computer user to change or disable access to a personal computer system, access to one or more general functions of said personal computer system being controlled by a system password if said system password is enabled, and access to one or more administrative functions of said personal computer system being controlled by a setup password is said setup password is enabled, said system password, if enabled, required to be entered by said user during initiation of said computer system as a condition to allowing said user to utilize said one or more general functions of said computer system, and said setup password, if enabled, required to be entered by said user during execution of a setup program as a condition to allowing said user to utilize said one or more administrative functions of said computer system, comprising:

• (a) storing within said computer system a system password status associated with said system password, said system password status being in either a "locked" or "unlocked" state;
• (b) receiving a request from said user to change or disable access to said personal computer system;
• (c) determining whether said request is a request to disable said system password or a request to change said system password;
• (d) if said request is a request to disable said system password, then disabling said system password only if said system password status is "unlocked";
• and
• (e) if said request is a request to change said system password, then permitting said user to change said system password if said setup password is disabled, or if said setup password is enabled and said user correctly entered said setup password.

An apparatus for securing a personal computer system, said personal computer system having a system password for controlling access to one or more general functions of said personal computer system, and a setup password for controlling access to one or more administrator functions of said personal computer system, comprising:

• (a) means for detecting a user request to disable or change said system password;
• (b) means for determining whether said user request to disable or change said system password is permitted, wherein said means for determining comprises:
• (i) means for storing a system password status in a memory device associated with said personal computer system, said system password status being associated with said system password, and said system password status being in either a "locked" or "unlocked" state;
• (ii) means for determining whether said system password status is "locked" or "unlocked";
• and
• (iii) means for indicating that said user request to disable or change said system password is permitted, if said system password status is "locked";
• and
• (c) means for permitting said user request to disable or change said system password, if said user request to disable or change said system password is permitted.
