841 This option supports all of the Octeon reference boards from Cavium
842 Networks. It builds a kernel that dynamically determines the Octeon
843 CPU type and supports all known board reference implementations.
844 Some of the supported boards are:
845 EBT3000
846 EBH3000
847 EBH3100
848 Thunder
849 Kodama
850 Hikari
851 Say Y here for most Octeon reference boards.

1431 Please make sure to pick the right CPU type. Linux/MIPS is not
1432 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1433 *not* work on R4000 machines and vice versa. However, since most
1434 of the supported machines have an R4000 (or similar) CPU, R4x00
1435 might be a safe bet. If the resulting kernel does not work,
1436 try to recompile with R3000.

2704 Find out whether you have a PCI motherboard. PCI is the name of a
2705 bus system, i.e. the way the CPU talks to the other stuff inside
2706 your box. Other bus systems are ISA, EISA, or VESA. If you have PCI,
2707 say Y, otherwise N.

2740 ---help---
2741 The Extended Industry Standard Architecture (EISA) bus was
2742 developed as an open alternative to the IBM MicroChannel bus.
2743
2744 The EISA bus provided some of the features of the IBM MicroChannel
2745 bus while maintaining backward compatibility with cards made for
2746 the older ISA bus. The EISA bus saw limited use between 1988 and
2747 1995 when it was made obsolete by the PCI bus.
2748
2749 Say Y here if you are building a kernel for an EISA-based machine.
2750
2751 Otherwise, say N.
