ERROR LOGGING DURING SYSTEM BOOT AND SHUTDOWN

Systems and methods are described for improved error logging during system boot and shutdown. A hardware initialization firmware on a computing device can include a logging module. When errors occur during early system booting or late system shutdown, the firmware can create error logs. The logging module can receive the error logs and prioritize them according to a set of rules. The logging module can select error logs of the highest priority up to a predetermined maximum amount. The logging module can modify the error logs using a shorthand form and write them to nonvolatile random-access memory. The firmware can initialize runtime services and launch an operating system. A system logger on the operating system can retrieve the error logs, save them to a file, and erase them from the memory.
