Abstract: A system and method that allows debugging data to be stored without slowing down initialization is disclosed. The system includes a processor, a firmware read only memory (ROM), and a first memory device coupled to the firmware ROM. The firmware ROM can be a BIOS ROM. The first memory device is configured to store debug information from the firmware ROM prior to running an operating system on the processor. Having the firmware ROM store the debug information on the first memory device allows debug information associated with the firmware to be easily accessible without needing a debug firmware or a cable to receive outputs of the debug firmware.

Abstract: A system and method for storing data associated with a system management interrupt (SMI) in a computer system. Notification of a system management interrupt is received on a central processing unit. The central processing unit enters a system management mode. A system management handler of a basic input output system (BIOS) is executed by a bootstrap processor of the central processing unit. The system management interrupt is initiated via the bootstrap processor. The system management interrupt data is stored in a register of the bootstrap processor. The SMI data is converted to an accessible format. The converted SMI data is stored in a memory.
