摘要:
A mechanism via which system state changes can be detected and corrected automatically prior to a customer initiated boot. The mechanism is extensible to address newly added or discovered system state changes that result in a locked condition. The mechanism detects and corrects adverse events before booting into the operating system.

摘要:
A method for registering and initiating a pre-boot environment for enabling partitions. The method provides a basic input output system (CIOS) with an application program interface (API) that accesses a Logical Clock Address (LCA) sector number when a boot configuration flag is set, the LCA sector number stores an operating environment manager which then boots the information handling system to an appropriate partition.

摘要:
An information handling system which supports Pre-Boot Authentication (PBA) and which provides the ability for each authorized user of the system to have a unique ID and key at the BIOS level. In these systems, a user only needs knowledge of the traditional BIOS password only at the time the user is enrolled in the PBA feature. Later changes to the password do not have the effect of denying access to enrolled users.

A system for source language module interaction using an event mechanism includes one or more subsystems to detect a producer event, detect a consumer event, generate a new source language method for the producer event and a new source language method for the consumer event, and link the producer event and the consumer event using the new source language method. In an embodiment, the source language may be ASL.

摘要:
In a Uniform Extensible Firmware Interface (UEFI) environment, a system management mode (SMM) driver and a non-SMM driver may be installed for the same hardware device. Until the SMM driver is available, the non-SMM driver is configured to conduct input/output (IO) transactions directly with the hardware device. The non-SMM driver can utilize native UEFI services to receive a notification that the SMM driver is available. Upon receiving such notification, (or if the SMM driver was already available before the non-SMM driver), the non-SMM driver is reconfigured to redirect all IO requests to the SMM driver, which then conducts the corresponding IO transactions directly with the hardware device. Redirecting all non-SMM IO requests for a hardware device to the SMM driver for the hardware device limits direct access to the hardware device to only one driver, the SMM driver, thereby facilitating the integrity or atomicity of IO transactions.
