用于安全恢复主机系统代码的系统和方法
摘要：
管理控制器可以被配置为根据多种操作模式控制主机系统处理器、主ROM和恢复ROM之间的连接，所述多种操作模式包括至少一个正常模式，所述正常模式响应于没有ROM代码损坏而发生，在该模式下，所述管理控制器使所述主机系统处理器通信地联结到所述主ROM并且与所述恢复ROM通信地分离，使得所述主机系统处理器在所述主机系统的启动期间加载和执行所述ROM代码，以及所述主ROM响应于存在所述ROM代码的损坏而发生的主ROM恢复模式，在该模式中，所述管理控制器使所述主机系统处理器联结到所述主ROM和所述恢复ROM，使得所述主机系统处理器在所述主机系统启动期间加载并执行所述恢复代码。
摘要（英）：

A management controller may be configured to control connectivity among a host system processor, a primary ROM, and a recovery ROM in accordance with a plurality of modes of operation including at least a normal mode that occurs in response to absence of a corruption of the ROM code in which the management controller causes the host system processor to be communicatively coupled to the primary ROMand communicatively decoupled from the recovery ROM, such that the host system processor loads and executes the ROM code during boot of the host system, and a primary ROM recovery mode that occurs inresponse to presence of the corruption of the ROM code in which the management controller causes the host system processor to be coupled to the primary ROM and the recovery ROM, such that the host system processor loads and executes the recovery code during boot of the host system.
