    • A data processing system and method including a docking station and a portable computer capable of being coupled to the docking station are disclosed for securing the docking station, the portable computer, and for securing the attachment of the docking station to the portable computer. The portable computer is coupled to the docking station. A disconnection password is established. When the portable computer is disconnected from the docking station, a user is prompted for the disconnection password. The portable computer is disabled in response to a failure to correctly enter the disconnection password, wherein the portable computer is inoperable without a correct entry of the disconnection password. When a portable computer is connected to the docking station, a correct entry of a connection password is required. In response to a failure to correctly enter the connection password, access to the docking station is prohibited. When the docking station is physically removed from its stationary support, correct entry of a relocation password is required. In response to a failure to correctly enter the password, access to the docking station is prohibited.
    • 公开了一种数据处理系统和方法,其包括对接站和能够连接到对接站的便携式计算机,用于固定对接站,便携式计算机,以及用于将对接站的连接固定到便携式计算机。 便携式计算机耦合到对接站。 断开密码建立。 当便携式计算机与对接站断开连接时,提示用户断开连接密码。 响应于无法正确输入断开密码,便携式计算机被禁用,其中便携式计算机在不正确输入断开密码的情况下是不可操作的。 当便携式计算机连接到扩展坞时,需要正确输入连接密码。 响应于无法正确输入连接密码,禁止访问扩展坞。 当对接站从其固定支架物理上移除时,需要正确输入重新定位密码。 为了不正确输入密码,禁止访问扩展坞。

    • A data processing system and method are described for remotely rendering a client computer system inoperable. The client computer system is coupled, to a server computer system utilizing a network. The client computer system is initially powered off. The server computer system transmits a signal to the client computer system utilizing the network to prohibit the client computer system from becoming operable. In response to a receipt of the signal by the client computer system, the client computer system is prohibited from becoming operable. The server computer system remotely renders the client computer system inoperable. Alternatively, the client computer system is capable of receiving wireless signals transmitted by the server computer system. The server computer transmits a wireless signal to the client computer system to prohibit the client computer system from becoming operable. In response to a receipt of the wireless signal by the client computer system, the client computer system is prohibited from becoming operable. The server computer system remotely renders the client computer system inoperable utilizing a wireless signal.
    • 描述了用于远程呈现客户端计算机系统不可操作的数据处理系统和方法。 客户端计算机系统耦合到利用网络的服务器计算机系统。 客户端计算机系统最初关闭电源。 服务器计算机系统利用网络将信号发送到客户端计算机系统,以禁止客户端计算机系统变得可操作。 响应于客户端计算机系统接收到信号,客户端计算机系统被禁止变得可操作。 服务器计算机系统远程呈现客户端计算机系统不可操作。 或者,客户端计算机系统能够接收由服务器计算机系统发送的无线信号。 服务器计算机向客户端计算机系统发送无线信号以禁止客户端计算机系统变得可操作。 响应于客户端计算机系统接收到无线信号,客户端计算机系统被禁止变得可操作。 服务器计算机系统使用无线信号远程呈现客户端计算机系统不可操作。

    • Disclosed is a personal computer system which includes a central processing unit (CPU) coupled to a direct access storage device (DASD), a random access memory (RAM), and a LAN controller. A flash memory module is coupled to the CPU and an input/output (IO) bus and includes a basic input output system (BIOS) stored therein. The BIOS is effective for responding to the energization of the computer system by initiating a power on self test (POST). The BIOS is further operative on completion of the POST for transferring a portion of BIOS from the module to the RAM and for transferring control of the of the computer system to the BIOS portion. The portion of BIOS is operative to load a protected mode operating system (OS) into RAM and transfer control to the OS. The system further includes a logic circuit coupled to the flash memory module and the IO bus. A communication subsystem is coupled to the IO bus, the logic circuit and the flash memory for allowing the remote computer to access the BIOS in flash memory while the protected mode OS is running.
    • 公开了一种个人计算机系统,其包括耦合到直接存取存储设备(DASD),随机存取存储器(RAM)和LAN控制器的中央处理单元(CPU)。 闪存模块耦合到CPU和输入/输出(IO)总线,并且包括存储在其中的基本输入输出系统(BIOS)。 BIOS通过启动电源自检(POST)来响应计算机系统的通电。 在完成POST以将BIOS的一部分从模块传送到RAM并用于将计算机系统的控制传送到BIOS部分的同时,BIOS进一步操作。 BIOS的部分操作是将保护模式操作系统(OS)加载到RAM中,并将控制传输到OS。 该系统还包括耦合到闪存模块和IO总线的逻辑电路。 通信子系统耦合到IO总线,逻辑电路和闪存,用于允许远程计算机在保护模式OS正在运行时访问闪存中的BIOS。
