    Abstract: A system, computer program product and method for booting to a partition in a non-volatile storage unit without a local operator. In one embodiment, one or more bits in a BOOT register may be set by an operating system indicating if the BIOS should boot to the partition. The BIOS may then read the BOOT register to determine if the BIOS is to boot to the partition as well as any activities to perform if the BIOS is to boot to the partition. In another embodiment, a network interface card may insert directive information received from a packet in a register within the network interface card. The BIOS may then read the register within the network interface card to determine if the BIOS is to boot to the partition as well as any activities to perform if the BIOS is to boot to the partition.

    Abstract: During power up initialization, security data such as passwords and other sensitive data which are stored in a lockable memory device are read and copied to protected system management interrupt (SMI) memory space, subject to verification by code running in the SMI memory space that the call to write the security data originates with a trusted entity. Once copied to SMI memory space, the security data is erased from regular system memory and the lockable storage device is hard locked (requiring a reset to unlock) against direct access prior to starting the operating system. The copy of the security data within the SMI memory space is invisible to the operating system. However, the operating system may initiate a call to code running in the SMI memory space to check a password entered by the user, with the SMI code returning a “match” or “no match” indication. The security data may thus be employed after the lockable memory device is hard locked and the operating system is started.

    Abstract translation: 在上电初始化期间，存储在可锁定存储器设备中的安全数据（例如密码和其他敏感数据）被读取并复制到受保护的系统管理中断（SMI）存储器空间，经由在SMI存储器空间中运行的代码进行验证， 调用写入安全数据来源于受信任的实体。 一旦复制到SMI内存空间，安全数据将从常规系统内存中擦除，锁定的存储设备在启动操作系统之前就被硬锁定（需要重新启动）以防止直接访问。 SMI内存空间中的安全数据的副本对于操作系统是不可见的。 然而，操作系统可以启动对在SMI存储器空间中运行的代码的调用，以检查由用户输入的密码，SMI代码返回“匹配”或“不匹配”指示。 因此，在可锁定存储器件被硬锁定并且操作系统启动之后可以采用安全数据。

    Abstract: A computer system processor incorporates a special S-latch which may only be set by secure signals. One state of the S-latch sets the processor into a secure mode where it only executes instructions and not commands from an In Circuit Emulator (ICE) unit. A second state of the S-latch sets the processor into a non-secure mode. A non-volatile random access memory (NVRAM) is written with secure data which can only be read by boot block code stored in a BIOS storage device. The boot block code is operable to read the secure data in the NVRAM and set the S-latch to an appropriate security state. If the boot block code cannot set the S-latch, then remaining boot up with BIOS data is stopped. On boot up the boot block code reads the NVRAM and sets the S-latch into the appropriate security state.

    Abstract translation: 计算机系统处理器包括只能由安全信号设置的特殊S-锁存器。 S锁存器的一个状态将处理器设置为安全模式，其中它只执行指令而不是来自In Circuit Emulator（ICE）单元的命令。 S锁存器的第二状态将处理器设置为非安全模式。 用非易失性随机存取存储器（NVRAM）写入只能由存储在BIOS存储设备中的引导块代码读取的安全数据。 引导块代码可操作以读取NVRAM中的安全数据并将S锁存器设置为适当的安全状态。 如果引导块代码无法设置S锁存器，则停止使用BIOS数据进行剩余引导。 启动引导块代码读取NVRAM并将S锁存器设置为适当的安全状态。

    Abstract: A method for remotely powering up a computer, includes: receiving a telephone call by a device coupled to a powered down computer; determining an originator's telephone number for the telephone call; determining if the originator's telephone number matches one of a plurality of authorized telephone numbers; and powering up the computer if the originator's telephone number matches one of the plurality of authorized telephone numbers. The method and system utilizes the well known “Caller-ID” technology to determine the originator's telephone number for a telephone call received by a modem coupled to the computer. If there is no match, the computer remains in a powered down state. In this manner, the system discriminates between the received telephone calls, and avoids powering up the computer when the received call is not for this purpose. This avoids wasting power.

    Abstract: A periodic system “wake-up” is implemented during S1, S2 or S3 states utilizing a hardware timer. A memory scrubbing routine is initiated that reads out all memory locations and writes back any memory locations that have single bit (correctable) Error Correction Code errors. This procedure minimizes the chances of a multiple bit error build up over time that may cause an unrecoverable error. The scrubbing routine is invoked whenever the system is brought out of S1, S2, or S3 state to insure that there are no single bit errors present when full system operation is resumed.

    Abstract translation: 在使用硬件定时器的S1，S2或S3状态期间实现周期性系统“唤醒”。 启动内存清理例程，读取所有存储器位置并写入具有单个位（可校正）错误更正代码错误的任何存储器位置。 此过程可以最大程度地减少可能导致不可恢复错误的多个位错误累积的可能性。 每当系统从S1，S2或S3状态退出时，将调用擦除程序，以确保在完全系统操作恢复时不存在单个位错误。

    Abstract: A computer program product and system for reducing the boot time of a TCPA based computing system. A flash memory in the TCPA based computing system may include a register comprising bits configured to indicate whether the segments of the flash memory have been updated. The flash memory may further include a table configured to store measurements of the segments of the flash memory. The flash memory may further include a boot block code that includes a Core Root of Trust for Measurement (CRTM). The CRTM may read the bits in the register to determine if any of the segments of the flash memory have been updated. The CRTM may further obtain the measurement values in the table for those segments that store the POST BIOS code that have not been updated thereby saving time from measuring the POST BIOS code and consequently reducing the boot time.
