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.

1212 Choose this option to build a kernel for release 2 or later of the
1213 MIPS64 architecture. Many modern embedded systems with a 64-bit
1214 MIPS processor are based on a MIPS64 processor. If you know the
1215 specific type of processor in your system, choose those that one
1216 otherwise CPU_MIPS64_R1 is a safe bet for any MIPS64 system.

1225 Please make sure to pick the right CPU type. Linux/MIPS is not
1226 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1227 *not* work on R4000 machines and vice versa. However, since most
1228 of the supported machines have an R4000 (or similar) CPU, R4x00
1229 might be a safe bet. If the resulting kernel does not work,
1230 try to recompile with R3000.

1778 Virtual SMP uses the processor's VPEs to implement virtual
1779 processors. In currently available configuration of the 34K processor
1780 this allows for a dual processor. Both processors will share the same
1781 primary caches; each will obtain the half of the TLB for it's own
1782 exclusive use. For a layman this model can be described as similar to
1783 what Intel calls Hyperthreading.

2280 Find out whether you have a PCI motherboard. PCI is the name of a
2281 bus system, i.e. the way the CPU talks to the other stuff inside
2282 your box. Other bus systems are ISA, EISA, or VESA. If you have PCI,
2283 say Y, otherwise N.

2304 The Extended Industry Standard Architecture (EISA) bus was
2305 developed as an open alternative to the IBM MicroChannel bus.
2306
2307 The EISA bus provided some of the features of the IBM MicroChannel
2308 bus while maintaining backward compatibility with cards made for
2309 the older ISA bus. The EISA bus saw limited use between 1988 and
2310 1995 when it was made obsolete by the PCI bus.
2311
2312 Say Y here if you are building a kernel for an EISA-based machine.
