Abstract
Methods and apparatus to facilitate fast restarts in processor systems are disclosed. An example processor restart method disclosed herein includes recording a log of pre-boot initialization actions, and replaying a portion of the log during subsequent processor restarts to shorten pre-boot initialization time. The example processor restart method disclosed herein may further include creating a log index table for easier referral to portions of the log, storing the log and the log index table in non-volatile memory, using the log index table to reorder the replaying of the log, and reordering the replay of the log to initialize the video graphics adapter earlier in a processor restart sequence.
