摘要： An example computing device may include a random-access memory, a basic input/output system (BIOS) memory storing a first ordered group of initialization instructions in a first firmware volume of the BIOS memory, and a central processing unit (CPU). The CPU is to store an update for the first ordered group of initialization instructions in a second firmware volume of the BIOS memory, and store a second ordered group of initialization instructions in the second firmware volume, wherein the second ordered group of initialization instructions are different from an update of initialization instructions. The CPU is to copy the update and the second group of initialization instructions to the random-access memory.

摘要： Examples associated with password updates are described. One example method includes receiving a request to modify an administrator password in a basic input/output system (BIOS). The administrator password may be updated. A first password tied to the administrator password may be identified. A first updated password is generated by concatenating a character string to the administrator password. The character string may be generated based on a password policy for the first password. The first password may then be updated to the first updated password.

摘要： A storage may store machine-readable instructions for execution by a processor. Execution of the machine-readable instructions may cause the processor to receive an update capsule via a firmware update interface. The update capsule may include a device identifier and a payload. The payload may include data that is different from a firmware update. Execution of the machine-readable instructions may cause the processor to execute a virtual device handler, based on the device identifier, to process the payload.

摘要： An authentication system is disclosed herein. An example includes a computing device and a port associated with the computing device for connection of an accessory to the computing device. The example also includes an authentication device that generates an accessory response upon receipt of a challenge and a hardware controller. The hardware controller generates both the challenge and an expected response to the challenge. It compares the expected response to the accessory response to ascertain if the accessory response is one of a valid response and an invalid response, and it signals for the port to be enabled for the valid response to allow access to functionality of the accessory by the computing device. Other features and components of the authentication system are also disclosed herein, as is a method of authenticating an accessory for use by a computing device.

摘要： In some examples, a computing device, includes a first hardware device, a first firmware component coupled to the first hardware device, a second hardware device, a bus, and a basic input/output system (BIOS). In some examples, the BIOS is coupled to the first hardware device and to the second hardware device by the bus. In some examples, during a boot sequence, the BIOS is to set the second hardware device to a reset state. In some examples, the BIOS is to update instructions to the first firmware component via the bus while the second hardware device is in the reset state. In some examples, the BIOS is to lock the bus after the instructions are updated.

摘要： A method of protecting basic input/output system (BIOS) code. The method includes, with a relocation information tool executed by a processor, refactoring a number of data sections within a number of handlers of the BIOS code to tag a number of variables within the handlers. The tags indicate which of the variables should be protected at runtime. The method further includes generating a relocation file comprising a number of relocation addresses identifying locations of a number of dynamic variables that change at runtime. The relocation addresses point to a location within the handlers different from an original location. The method further includes, with a loader, loading at runtime the relocation file as part of a BIOS firmware image and adjusting data access to the dynamic variables in handler code to identify the location of the dynamic variables based on the relocation file.
摘要翻译：一种保护基本输入/输出系统（BIOS）代码的方法。该方法包括利用由处理器执行的重定位信息工具来重构BIOS代码的多个处理程序内的多个数据部分以标记处理程序内的多个变量。标签指示哪些变量应在运行时受到保护。该方法还包括生成重定位文件，该重定位文件包括标识在运行时改变的多个动态变量的位置的多个重定位地址。重定位地址指向与原始位置不同的处理程序内的位置。该方法还包括利用加载程序在运行时加载重定位文件作为BIOS固件映像的一部分，并调整对处理程序代码中的动态变量的数据访问以基于重定位文件来识别动态变量的位置。
