Abstract: Error data is read from error registers and written into a buffer. A computing node uses a BIOS to read the error data, rearm the error register and write the data into a memory mapped buffer. A hub chip supports creation of a shared memory system of computing nodes. A management controller in the computing node extracts error data from the buffer. The error data preferably consists essentially of the error register identifiers and the contents of the error registers. A system management node receives the error data from the management controllers in the computing nodes. The system management node may be coupled to but separate from the computing nodes.
