SYSTEM MANAGEMENT MODE (SMM) ERROR HANDLER - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 17724811 Titled 'SYSTEM MANAGEMENT MODE (SMM) ERROR HANDLER'
Simplified Explanation
This technology involves a processor entering a mode that is not visible to the operating system (OS). When this happens, a flag is set to indicate the entry into this mode, and an identifier (ID) of the error causing the entry is saved. If a system reset is initiated while in this mode, the basic input/output system (BIOS) is booted. During this booting process, an error record is created, which can be accessed by the OS after booting. This error record includes the flag and the error ID. Finally, the OS is booted.
