Abstract: Authentication of an entity remotely managing a data processing system is enabled to allow changes by the remote entity to hard-locked critical security information normally accessible only during the POST and only to trusted entities such as the system BIOS. The remote entity builds a change request and generates a hash from the change request with a current password appended. The change request and the hash are stored in a lockable non-volatile buffer which, once locked, requires a system reset to access. During the next POST, a trusted entity such as the system BIOS reads the change request, generates an authentication hash from the change request and the current password within the hard-locked security information, and compares the buffered hash with the generated hash. If a match is determined, the security information is updated; otherwise a tamper error is reported.

Abstract translation: 允许远程管理数据处理系统的实体的认证允许远程实体更改硬锁定通常只能在POST期间可访问的关键安全性信息，并且只允许受信任的实体（如系统BIOS）。 远程实体构建更改请求，并从附加当前密码的更改请求生成哈希值。 更改请求和哈希存储在可锁定的非易失性缓冲区中，该缓冲区一旦被锁定就需要系统重置才能访问。 在下一个POST期间，诸如系统BIOS的受信任的实体读取更改请求，从改变请求中生成认证散列，并在硬锁定的安全信息内生成当前密码，并将缓冲的散列与生成的散列进行比较。 如果确定匹配，则更新安全信息; 否则报告篡改错误。

Abstract: A data processing system and method are described for controlling power supplied to the system. The system includes an internal power supply for receiving energy from an external source and supplying the energy to the system. The energy is full system power and is required for the system to be fully operable. The system is initially powered-off such that the energy is not initially supplied to the system. A power-on password is established. The internal power supply supplies the energy to the system only in response to a correct entry of the power-on password, wherein the system is inoperable prior to the correct entry of the power-on password.

Abstract: Disclosed is a method for reducing power-up time and avoiding customer-induced failures of computer systems during power-up. An intrusion switch, which is connected to the inside frame of the computer system is utilized. The intrusion switch signals the BIOS of the computer system whenever the cover of the computer's system unit is opened. The BIOS controls the POST operation during power-up of the computer system. During an initial power-up of the computer system, the POST configuration code examines and configures the hardware and sets the applicable registers, etc. At the end of the POST configuration code, the register values are stored in non-volatile storage. During a subsequent power-up of the computer system, a check is made to see if the cover of the system had been opened. When the cover has not been opened, the BIOS assumes that no changed has occurred in the hardware configuration and the BIOS restores the register values from non-volatile storage without completing the POST operation. When the cover has been opened, the BIOS discards the register values and initiates the POST operation, i.e., a full configuration operation is performed and new values stored in the registers and non-volatile storage element.

Abstract translation: 公开了一种在上电期间减少上电时间并避免客户导致的计算机系统故障的方法。 使用连接到计算机系统的内部框架的入侵开关。 每当打开计算机系统单元的盖子时，入侵开关就会通知计算机系统的BIOS。 BIOS在电脑系统启动期间控制POST操作。 在计算机系统的初始上电期间，POST配置代码检查和配置硬件并设置适用的寄存器等。在POST配置代码结束时，寄存器值存储在非易失性存储器中。 在计算机系统的随后上电期间，检查系统的盖是否已打开。 当盖子尚未打开时，BIOS假定在硬件配置中没有发生任何变化，BIOS会从非易失性存储器中恢复寄存器值，而无需完成POST操作。 当盖子打开时，BIOS将丢弃寄存器值并启动POST操作，即执行完整配置操作，并将新值存储在寄存器和非易失性存储元件中。
