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

1452 might be a safe bet. If the resulting kernel does not work,

2668 Although binutils currently supports use of this flag the details
2669 concerning its effect upon the O32 ABI in userland are still being
2670 worked on. In order to avoid userland becoming dependant upon current
2671 behaviour before the details have been finalised, this option should
2672 be considered experimental and only enabled by those working upon
2673 said details.

2800 The Extended Industry Standard Architecture (EISA) bus was
2801 developed as an open alternative to the IBM MicroChannel bus.
2802
2803 The EISA bus provided some of the features of the IBM MicroChannel
2804 bus while maintaining backward compatibility with cards made for
2805 the older ISA bus. The EISA bus saw limited use between 1988 and
2806 1995 when it was made obsolete by the PCI bus.
2807
2808 Say Y here if you are building a kernel for an EISA-based machine.
