853 This option supports all of the Octeon reference boards from Cavium
854 Networks. It builds a kernel that dynamically determines the Octeon
855 CPU type and supports all known board reference implementations.
856 Some of the supported boards are:
857 EBT3000

2795 The Extended Industry Standard Architecture (EISA) bus was
2796 developed as an open alternative to the IBM MicroChannel bus.

2798 The EISA bus provided some of the features of the IBM MicroChannel
2799 bus while maintaining backward compatibility with cards made for
2800 the older ISA bus. The EISA bus saw limited use between 1988 and
2801 1995 when it was made obsolete by the PCI bus.
