1214 Please make sure to pick the right CPU type. Linux/MIPS is not
1215 designed to be generic, i.e. Kernels compiled for R3000 CPUs will
1216 *not* work on R4000 machines and vice versa. However, since most
1217 of the supported machines have an R4000 (or similar) CPU, R4x00
1218 might be a safe bet. If the resulting kernel does not work,
1219 try to recompile with R3000.

1767 Virtual SMP uses the processor's VPEs to implement virtual
1768 processors. In currently available configuration of the 34K processor
1769 this allows for a dual processor. Both processors will share the same
1770 primary caches; each will obtain the half of the TLB for it's own

1772 what Intel calls Hyperthreading.

1922 SmartMIPS is a extension of the MIPS32 architecture aimed at
1923 increased security at both hardware and software level for
1924 smartcards. Enabling this option will allow proper use of the
1925 SmartMIPS instructions by Linux applications. However a kernel with
1926 this option will not work on a MIPS core without SmartMIPS core. If
1927 you don't know you probably don't have SmartMIPS and should say N

2293 The Extended Industry Standard Architecture (EISA) bus was
2294 developed as an open alternative to the IBM MicroChannel bus.
2295
2296 The EISA bus provided some of the features of the IBM MicroChannel
2297 bus while maintaining backward compatibility with cards made for
2298 the older ISA bus. The EISA bus saw limited use between 1988 and
2299 1995 when it was made obsolete by the PCI bus.
2300
2301 Say Y here if you are building a kernel for an EISA-based machine.
2302
2303 Otherwise, say N.
