Abstract
The BIOS of a multiple processor system passes partial control to the operating system following an abbreviated power-on initialization. The BIOS program retains control of one or more processors and any memory that was untested during power-on. While the operating system is loaded and the system is operational, the BIOS program tests the retained memory. The BIOS program then relinquishes control of the retained memory and processor(s) during runtime to the operating system.
