1217 Please make sure to pick the right CPU type. Linux/MIPS is not
1218 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1219 *not* work on R4000 machines and vice versa. However, since most
1220 of the supported machines have an R4000 (or similar) CPU, R4x00
1221 might be a safe bet. If the resulting kernel does not work,
1222 try to recompile with R3000.

1770 Virtual SMP uses the processor's VPEs to implement virtual
1771 processors. In currently available configuration of the 34K processor
1772 this allows for a dual processor. Both processors will share the same
1773 primary caches; each will obtain the half of the TLB for it's own
1774 exclusive use. For a layman this model can be described as similar to
1775 what Intel calls Hyperthreading.

1925 SmartMIPS is a extension of the MIPS32 architecture aimed at
1926 increased security at both hardware and software level for
1927 smartcards. Enabling this option will allow proper use of the
1928 SmartMIPS instructions by Linux applications. However a kernel with
1929 this option will not work on a MIPS core without SmartMIPS core. If

2296 The Extended Industry Standard Architecture (EISA) bus was
2297 developed as an open alternative to the IBM MicroChannel bus.
2298
2299 The EISA bus provided some of the features of the IBM MicroChannel
2300 bus while maintaining backward compatibility with cards made for
2301 the older ISA bus. The EISA bus saw limited use between 1988 and
2302 1995 when it was made obsolete by the PCI bus.
2303
2304 Say Y here if you are building a kernel for an EISA-based machine.
2305
2306 Otherwise, say N.
