727 Networks. It builds a kernel that dynamically determines the Octeon
728 CPU type and supports all known board reference implementations.
729 Some of the supported boards are:
730 EBT3000
731 EBH3000
732 EBH3100
733 Thunder
734 Kodama
735 Hikari
736 Say Y here for most Octeon reference boards.

1205 Choose this option to build a kernel for release 2 or later of the
1206 MIPS64 architecture. Many modern embedded systems with a 64-bit
1207 MIPS processor are based on a MIPS64 processor. If you know the
1208 specific type of processor in your system, choose those that one
1209 otherwise CPU_MIPS64_R1 is a safe bet for any MIPS64 system.

1218 Please make sure to pick the right CPU type. Linux/MIPS is not
1219 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1220 *not* work on R4000 machines and vice versa. However, since most
1221 of the supported machines have an R4000 (or similar) CPU, R4x00
1222 might be a safe bet. If the resulting kernel does not work,
1223 try to recompile with R3000.

1771 Virtual SMP uses the processor's VPEs to implement virtual
1772 processors. In currently available configuration of the 34K processor
1773 this allows for a dual processor. Both processors will share the same
1774 primary caches; each will obtain the half of the TLB for it's own
1775 exclusive use. For a layman this model can be described as similar to
1776 what Intel calls Hyperthreading.

1927 increased security at both hardware and software level for

2297 The Extended Industry Standard Architecture (EISA) bus was
2298 developed as an open alternative to the IBM MicroChannel bus.
2299
2300 The EISA bus provided some of the features of the IBM MicroChannel
2301 bus while maintaining backward compatibility with cards made for
2302 the older ISA bus. The EISA bus saw limited use between 1988 and
2303 1995 when it was made obsolete by the PCI bus.
2304
2305 Say Y here if you are building a kernel for an EISA-based machine.
2306
2307 Otherwise, say N.
