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.

1210 Choose this option to build a kernel for release 2 or later of the
1211 MIPS64 architecture. Many modern embedded systems with a 64-bit
1212 MIPS processor are based on a MIPS64 processor. If you know the
1213 specific type of processor in your system, choose those that one
1214 otherwise CPU_MIPS64_R1 is a safe bet for any MIPS64 system.

1223 Please make sure to pick the right CPU type. Linux/MIPS is not
1224 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1225 *not* work on R4000 machines and vice versa. However, since most
1226 of the supported machines have an R4000 (or similar) CPU, R4x00
1227 might be a safe bet. If the resulting kernel does not work,
1228 try to recompile with R3000.

1774 Virtual SMP uses the processor's VPEs to implement virtual
1775 processors. In currently available configuration of the 34K processor
1776 this allows for a dual processor. Both processors will share the same
1777 primary caches; each will obtain the half of the TLB for it's own
1778 exclusive use. For a layman this model can be described as similar to
1779 what Intel calls Hyperthreading.

2300 The Extended Industry Standard Architecture (EISA) bus was
2301 developed as an open alternative to the IBM MicroChannel bus.
2302
2303 The EISA bus provided some of the features of the IBM MicroChannel
2304 bus while maintaining backward compatibility with cards made for
2305 the older ISA bus. The EISA bus saw limited use between 1988 and
2306 1995 when it was made obsolete by the PCI bus.
2307
2308 Say Y here if you are building a kernel for an EISA-based machine.
