摘要:
A method includes detecting a storage device that has a boot file and a relative path name that corresponds to the boot file, determining a hardware path name corresponding to the storage device, obtaining from the storage device the relative path name, combining the hardware path name and the relative path name to generate a full path name to the boot file, and storing the full path name within a persistent memory.
摘要:
An information handling system and a method of using it can allow the information handling system to be started or restarted and have an operating system loaded, even if a boot variable within a persistent memory is currently invalid. The method can detect and determine a hardware path name to a new drive that has an operating system. The new drive can have a relative path name to boot entries that include a pointer to a boot file. The boot file can be executed to run a boot loader that loads the operating system. During loading of the operating system, other boot entries within the drive can provide boot parameters. The boot variable within persistent memory, and potentially the relative path name or boot parameter(s) can be updated on the new drive. In a particular embodiment, the information handling system can include a unified extensible firmware interface (UEFI).

摘要:
An information handling system includes a firmware management infrastructure. The firmware management infrastructure includes a database that identifies a correspondence between members of a set of device paths and members of a set of correlatable identifier strings. A device path represents a platform-specific reference to an object at the information handling system and a correlatable identifier string represents a platform independent reference to the object. Programs can access the database using an application programming interface.
摘要:
A method can include, during a boot flow at an information handling system, receiving an initial device path related to a device that is integrated with or coupled to the information handling system. The method can also include identifying a system-specific device location table based on a node included in the initial device path and receiving a particular alternate location string associated with the node at the system-specific location table. Further, the method can include adding the particular alternate location string to an alternate device path string related to the device and outputting the alternate device path to a user after the alternate device path includes an alternate location string associated with each node of the initial device path.
