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

1213 Choose this option to build a kernel for release 2 or later of the
1214 MIPS64 architecture. Many modern embedded systems with a 64-bit
1215 MIPS processor are based on a MIPS64 processor. If you know the
1216 specific type of processor in your system, choose those that one
1217 otherwise CPU_MIPS64_R1 is a safe bet for any MIPS64 system.

1226 Please make sure to pick the right CPU type. Linux/MIPS is not
1227 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1228 *not* work on R4000 machines and vice versa. However, since most
1229 of the supported machines have an R4000 (or similar) CPU, R4x00
1230 might be a safe bet. If the resulting kernel does not work,
1231 try to recompile with R3000.

1779 Virtual SMP uses the processor's VPEs to implement virtual
1780 processors. In currently available configuration of the 34K processor
1781 this allows for a dual processor. Both processors will share the same
1782 primary caches; each will obtain the half of the TLB for it's own

1784 what Intel calls Hyperthreading.

2281 Find out whether you have a PCI motherboard. PCI is the name of a
2282 bus system, i.e. the way the CPU talks to the other stuff inside
2283 your box. Other bus systems are ISA, EISA, or VESA. If you have PCI,
2284 say Y, otherwise N.

2305 The Extended Industry Standard Architecture (EISA) bus was
2306 developed as an open alternative to the IBM MicroChannel bus.
2307
2308 The EISA bus provided some of the features of the IBM MicroChannel
2309 bus while maintaining backward compatibility with cards made for
2310 the older ISA bus. The EISA bus saw limited use between 1988 and
2311 1995 when it was made obsolete by the PCI bus.
2312
2313 Say Y here if you are building a kernel for an EISA-based machine.
