852 This option supports all of the Octeon reference boards from Cavium
853 Networks. It builds a kernel that dynamically determines the Octeon
854 CPU type and supports all known board reference implementations.

2796 The Extended Industry Standard Architecture (EISA) bus was
2797 developed as an open alternative to the IBM MicroChannel bus.
2798
2799 The EISA bus provided some of the features of the IBM MicroChannel
2800 bus while maintaining backward compatibility with cards made for
2801 the older ISA bus. The EISA bus saw limited use between 1988 and
2802 1995 when it was made obsolete by the PCI bus.
