摘要: Firmware of a system is configured to allow secondary devices, such as a smart card, to be used for authentication. In an example embodiment, the secondary device is a CCID smart card in compliance with the ISO 7816 specification. The smart card is inserted into a card reader coupled to the system prior to booting the system. The firmware comprises an emulator and driver configured to allow authentication information from the smart card to be utilized to allow execution of the boot process. In an example embodiment, the smart card comprises external keys for use with BITLOCKER™. The secondary device is compatible with systems implementing a BIOS and with systems implementing EFI. Authentication also can be accomplished via devices that do not provide data storage, such as a biometric device or the like.

摘要: A determination is made whether information scheduled to be broadcast is utilizing all bandwidth previous allocated to broadcasting the information, and if not, additional information is broadcast using an unused portion of the previously allocated bandwidth.
摘要翻译: 确定要广播的信息是否正在利用先前分配给广播信息的所有带宽,如果不是,则使用先前分配的带宽的未使用部分来广播附加信息。
