Introduction
The Ubox is a system configuration agent organized as a number of modular utilities.
Some of the different utilities include Intel SMI, scratch registers, test and set
registers, Flash ROM interface, CSR bridge, interval timer, VLW, Lock, exception, and
interrupts. It receives and sends Intel QuickPath Interconnect transactions to the rest
of the local Intel Xeon Processor E7-8800/4800/2800 Product Families and through the
Rbox port shared with a Bbox.
