Abstract
Monitoring of boot progress for a multiprocessor information handling system is performed with a test module running on a CPLD. RAM integrated in the CPLD stores boot progress information passed through an I/O buffer located between the processors and the firmware that boots the processors. Downloading of the boot progress from the RAM to an external device, such as through a serial port, provides a processor trace that is analysis and debugging of the firmware by recording processor operations through the boot progress.
