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.
855 Some of the supported boards are:
856 EBT3000
857 EBH3000
858 EBH3100
859 Thunder
860 Kodama
861 Hikari

2798 The Extended Industry Standard Architecture (EISA) bus was
2799 developed as an open alternative to the IBM MicroChannel bus.
2800
2801 The EISA bus provided some of the features of the IBM MicroChannel
2802 bus while maintaining backward compatibility with cards made for
2803 the older ISA bus. The EISA bus saw limited use between 1988 and
2804 1995 when it was made obsolete by the PCI bus.
2805
2806 Say Y here if you are building a kernel for an EISA-based machine.
