    • 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。

    • Described is a computer system which can be pre-set over a network to boot to a first or second remote boot protocol prior to being powered on over the network. The system is coupled to a remote computer via a data communication link. The system includes a communication subsystem for communicating data with the computer system. The communication subsystem is supplied with auxiliary power and is operative to communicate with the computer system regardless of whether the computer system is in a normal operating state. The remote computer includes a program for sending a first packet to the computer system via the communication link. The first packet contains a boot parameter which is indicative of the first or second remote boot protocol. The computer system is operative to receive the first packet via the communication subsystem and store the boot parameter in a memory thereof without powering on. The memory is accessed by BIOS during a network boot sequence and the system will boot in accordance with the specified boot protocol stored in the memory.
    • 描述了一种计算机系统,其可以在通过网络上电之前通过网络预先设置为引导到第一或第二远程启动协议。 该系统通过数据通信链路耦合到远程计算机。 该系统包括用于与计算机系统通信数据的通信子系统。 通信子系统具有辅助电源,并且可操作以与计算机系统通信,而不管计算机系统是否处于正常操作状态。 远程计算机包括用于经由通信链路向计算机系统发送第一分组的程序。 第一分组包含指示第一或第二远程启动协议的引导参数。 计算机系统可操作以经由通信子系统接收第一分组,并将引导参数存储在其存储器中而不加电。 在网络引导顺序期间,BIOS会访问存储器,系统将根据存储在存储器中的指定引导协议进行引导。

    • A computer system is disclosed that includes a primary processor and a service processor operable regardless of a power state of the computer system. A non-volatile memory device is communicatively coupled to the primary processor and the service processor. The non-volatile memory device stores firmware which includes a first list of patches required for installation on the computer system and a second list of patches previously installed on the computer system. A comparator module is provided to determine whether there are patches included in the first list that are not included in second list. A boot module is provided to boot a maintenance operating system in the event the first list includes patches not included in the second list. The maintenance operating system is configured to install, on the computer system, patches included in the first list but not the second list.
    • 公开了一种包括主处理器和服务处理器的计算机系统,其可操作而不管计算机系统的功率状态如何。 非易失性存储器设备通信地耦合到主处理器和服务处理器。 非易失性存储器设备存储固件,其包括在计算机系统上安装所需的补丁的第一列表以及先前安装在计算机系统上的补丁的第二列表。 提供比较器模块以确定在第一列表中是否包括未包括在第二列表中的补丁。 提供引导模块以在第一列表包括不包括在第二列表中的补丁的情况下引导维护操作系统。 维护操作系统被配置为在计算机系统上安装包括在第一列表中而不是第二列表中的补丁。
