855 This option supports all of the Octeon reference boards from Cavium
856 Networks. It builds a kernel that dynamically determines the Octeon
857 CPU type and supports all known board reference implementations.
858 Some of the supported boards are:
859 EBT3000
860 EBH3000
861 EBH3100
862 Thunder
863 Kodama
864 Hikari
865 Say Y here for most Octeon reference boards.

2802 The Extended Industry Standard Architecture (EISA) bus was
2803 developed as an open alternative to the IBM MicroChannel bus.
2804
2805 The EISA bus provided some of the features of the IBM MicroChannel
2806 bus while maintaining backward compatibility with cards made for
2807 the older ISA bus. The EISA bus saw limited use between 1988 and
2808 1995 when it was made obsolete by the PCI bus.
