Abstract
A system and method for implementing a fast reset of a computer system is described. In one implementation, the fast reset is implemented by adding a new ResetType to the EFIResetSystem( ) function. In particular, a third ResetType, i.e., “EfiResetFast” (FAST option), is added, which is passed as a parameter when calling the EFIResetSystem( ) function. In another implementation, the fast reset is implemented using a new EFI function, referred to herein as “EFIResetFast( )”. In either implementation, in response to a fast reset, the firmware skips several steps typically performed, including some of the core firmware construction, single cell initialization, memory testing, memory re-initialization, and partition creation, and proceeds directly to transfer of control of the platform to a software interface disposed between an OS and firmware.
